As they started making their way to Kristoff's love experts, they stopped by and grabbed Windshear and Toothless as his tail finally defrosted and he could fly normally again.

Hiccup, Olaf and Anna are flying on Toothless while Heather and Kristoff were riding Windshear with Sven on the dragons tail.

As they're flying, Heather is trying to stay warm as she feels herself getting colder.

"Heather, you sure you're okay to be flying?" Hiccup asks, not wanting her to fall off Windshear.

"I'll be okay, Hiccup." Heather promises and Hiccup moves closer to Windshear.

"Windshear, give us a little heat." Hiccup asks of the dragon and Windshear starts using her fire to warm her scales for Heather and she appreciates him doing that when Kristoff interrupts.

"Drop us down here." Kristoff asks of them and they land the dragons. "It's not much further from here." He promises and they start walking on foot.

"So, about my friends...well, I say friends, they're more like family." Kristoff explains. "Anyway, when I was a kid, it was just me and Sven. Until they, you know, kinda took us in. I don't want to scare anyone. They can be a little inappropriate and loud." He warns them and starts listing a bit more about his family.

"Kristoff, they sound wonderful." Anna states interrupting him as they reach a clearing with rocks everywhere.

"Okay, meet my family." Kristoff says gesturing to all the rocks. "Hey, guys." He greets the rocks and starts talking to them all.

"They're...rocks, right?" Heather asks as it seems even Toothless and Windshear are confused as Toothless is sniffing one of the rocks.

"Yeah, they're rocks." Hiccup confirms to her.

"He's crazy." Olaf whispers to them as Kristoff keeps talking to the rocks. "I'll distract him while you run." He tells them the plan and goes happily to the rocks.

"Hi, Sven's family! It's nice to meet you." Olaf says while petting the rocks. "Because I love you guys, I insist that you run." He whispers to them. "I understand you're love experts!" He goes back to happily speaking. "Why aren't you running?" Olaf asks seeing they're not leaving.

"Okay, you keep doing that. We're gonna start walking away." Heather says as Anna and Heather agree and begin walking away when all of the rocks start rolling towards Kristoff and Toothless follows them. To keep them safe, Windshear drops Hiccup and Heather onto her back away from the stampeding rocks

"Kristoff's home!" One of the trolls says and they all begin cheering.

"Kristoff's home!" Olaf also cheers when he realizes he's been calling him Sven this whole time. "Wait, Kristoff?" He asks the trolls.

"Let me look at you." One troll says and pulls Kristoff down to their level.

"Take off your clothes, I wash them." Another troll says.

"What? No, I'm going to keep my clothes on." Kristoff informs her. "Look, it's great to see you all, but where's grandpabbie?" He asks them.

"He's napping." One of the children trolls informs Kristoff.

"Okay, just so were clear, they're trolls, right?" Hiccup asks Heather since they've yet to notice them on Windshear's back.

"I thought I was just seeing things." Heather states just as confused.

"Trolls. They're trolls!" Anna just realized as all the trolls look her way.

"He's brought a girl!" One troll states and they move Anna towards Kristoff.

"What's going on?" Anna asks.

"I've learned to just roll with it." Kristoff tells her.

"Let me see. Bright eyes, working nose, strong teeth. Yes, yes. She.l do nicely for our Kristoff." One of the trolls asusres while looking over Anna.

"Wish, Wait, Wait. No." Anna starts interrupting.

"You've got the wrong idea." Kristoff states. "That's not why I brought them here." He says and they all just now noticed Hiccup and Heather on Windshear.

"Hi there." Hiccup greets them.

"What's the issue, dear?" The troll asks of Anna. "Why are you holding back from such a man?" She wonders.

"Is it the clumpy way he walks?" She asks while singing.

"What?" Kristoff questions.

"Or grumpy way he talks?" Another asks and starts singing.

"Or the pear-shaped, square-shaped weirdness of his feet?" Another comes in while holding Kristoff's foot.

"And though we know he washes well-he always ends up sort of smelly. But you'll never meet a fellow who's as sensitive and sweet!" Another group starts singing.

"That's nice, but..." Anna was trying to explain but they interrupt her with more singing and dragging Kristoff off.

"So, he's a bit of a fixer-upper, so he's got a few flaws. Like his peculiar brain-dear, his thing with the reindeer. That's a little outside of nature's laws!" The children start singing and keep playing with Sven, Olaf and Toothless.

"This isn't about me!" Kristoff tries explaining.

"So, he's a bit of a fixer-upper, but this we're certain of. You can fix this fixer-upper up with a little bit of love!" The trolls say and push Kristoff back towards Anna.

"Can we please just stop talking about this? We've got a real, actual problem here!" Kristoff keeps trying to explain.

"I'll say!" The female troll states. "So tell me, dear. Is it the way that he runs scared?"

"Or that he's socially impaired?" Another asks as a child troll comes up and Kristoff catches him.

"Or that he only likes to tinkle in the woods?" The child troll asks.

"That was something I didn't need to know." Heather comments while chuckling.

"Shouldn't we stop them?" Hiccup asks her.

"Give them a minute." Heather states, loving this.

"Are you holding back your fondness due to his unmanly blondness?" An elderly troll asks Anna and pushes Kristoff onto more trolls.

"Or the way he covers up that he's the honest goods?" They ask before rolling up into a shape of a heart.

"He's just a bit of a fixer-upper, he's got a couple of bugs."

"No, I don't!" Kristoff defends while scratching his head.

"His isolation is confirmation of his desperation for human hugs." They keep singing while hugging him.

"So he's a bit of a fixer-upper, but we know what to do." They keep singing and rope up Kristoff and Anna. "The way to fix up this fixer-upper is to fix him up with you!"

"ENOUGH! She is engaged to someone else, okay?!" Kristoff informs them all and they pull into a group huddle.

"So she's a bit of a fixer-upper." One of them says while the crystals around his neck glows. "That's a minor thing." Another agrees.

"Her quote 'engagement' is a flex arrangement." Another says while his crystals also glow.

"And by the way I don't see no ring!" One of the children states regarding Anna.

"So she's a bit of a fixer-upper, her brain's a bit betwixt! Get the fiance out of the way and the whole thing will be fixed!" The male trolls sing while huddling around Kristoff who's getting annoyed by his family.

With Anna, all the female trolls are doing the same to her just not huddling around her.

"We're not saying you can change her, 'cause people don't really change. We're only saying that love's a force that's powerful and strange. People make bad choices if they're mad, or scared, or stressed." She informs Anna and she starts rethinking some decisions she's made recently.

"But throw a little love their way (throw a little love their way) and you'll bring out their best. True love brings out their best!" They sing as they're dressing Anna up and the men finished with Kristoff.

"Everyone's a bit of a fixer-upper, that's what it's all about! Father! Sister! Brother! We need each other to raise us up and round us out. Everyone's a bit of a fixer-upper, but when push comes to shove." They sing when Olaf's Head onto; of Toothless comes in between the two.

"The only fixer-upper fixer that can fix up a fixer-upper is..." Olaf sings and Toothless moves them out of the way.

"True, true, true, true, true, true, love." The trolls keep singing and dig a pit before tossing them into it.

"Time to interrupt now?" Hiccup asks Heather.

"Yeah, go-" Heather was starting but more pain comes in and the same happened to Anna.

"She's as cold as ice." Kristoff says and Hiccup can concur the same about Heather when an older troll comes rolling through all of them.

"There is strange Magic here." Grandpabbie states. "Come, bring her here to me." He tells Kristoff and he holds Anna's hand. "Your lives are in danger. There is ice in your heart put there by Elsa. If not removed, to solid ice will you freeze, forever." He informs them.

"What?" Heather and Anna asks at the same time.

"But you can remove it, right?" Kristoff asks granpabbie.

"I cannot." He regretfully replies to Kristoff. "I'm sorry, if it was their heads, that would be easy. But only an act of true love can thaw a frozen heart." He explains to them.

"An act of true love?" Heather asks, confused. "Really?"

"A true love's kiss, perhaps?" One of the trolls offers and they all kiss their partner.

Heather looks at Hiccup as another wave of pain consumes her and her hair starts turning completely white.

"What do we have to loose?" Heather questions and pulls Hiccup into a kiss and her body suddenly starts warming back up and her hair turning back from white to raven black.

Hiccup looks over her and sees that it actually worked. "Our lives are complicated." Hiccup informs Heather.

"Yeah, no arguments there." Heather agrees and they look to Anna who's still freezing over.

"Anna, we have to get you back to Hans." Kristoff states and Anna agrees. "Pull is out, Sven." He asks of his reindeer and he does as Kristoff asked. "You guys coming?" He asks Heather and Hiccup.

"You know, maybe we'll try talking with Elsa before returning." Heather says and Hiccup agrees.

"Alright. Olaf, come on." Kristoff calls for the snowman.

"I'm coming!" Olaf says and runs onto Sven and they ride off to save Anna. "Lets go kiss Hans! Who is this Hans?" He questions since he never met Hans.

"Come on, I think we need to have a talk with Elsa." Heather says and they get on their dragons and take off into the sky.

-

Elsa herself is in her castle, pacing back and forward trying to control her powers. "Control it." She tells herself while looking down at her hands.

"Don't feel. Don't feel. Don't feel!" Elsa keeps saying as she looks around and sees the walls have become blood red and spikes start appearing and sees that she's loosing control.

Hiccup and Heather comes flying in through her balcony and see what's been happening.

"You think she wants to talk?" Hiccup asks Heather.

"I know what she's been feeling now. Feeling outcasted, no one to turn to. You helped me when I thought I was alone. I just need to do the same for her." Heather explains and gets off of Windshear.

"I'd join you, but I'd prefer not to keep slipping every few seconds." Hiccup says referring to the ice.

"Just hang tight." Says Heather before petting Windshear explaining to her to stay put.

Heather walks through the castle looking for Elsa and as she continues through the maze like halls, she starts to hear her talking to herself and finds her pacing.

"You know, ice and heels never really worked well together when you're walking." Heather jokes when Elsa just noticed her.

"How'd you get in here?" Elsa asks Heather while keeping her hands together.

"Me and Hiccup might've left out that we train dragons where we're from." Heather admits and Elsa is still as confused since she's never seen a dragon in Arendelle before.

"What are you doing back here?" Elsa questions her.

"Look, I get that you think you're dangerous. But Anna needs her sister." Heather tries explaining to her. "When you shot that showflake off of you, you sorta..froze our hearts. Literally speaking." She says and sees the look of horror on Elsa's face.

"Hey, no, it's okay." Heather assures her. "We were told that an act of true love will save us, so I'm okay. Anna on the other hand, she's on her way back to Arendelle for Hans."

"Why would she need me then?" Elsa asks her.

Heather takes a minute to figure what to say to her. "Before I met Hiccup, I lived with my family. Then a group called the Berserker tribe invaded, killed or imprisoned. I was able to escape, but I lost my family in the process. I had to run to survive, and I wish every day that I had time to fix my mistakes. You and Anna can still make up for lost time, sometimes all we need is someone who cares for us to understand what we need to do." She explains and Elsa starts to understand when they all hear Marshmallow in a fight.

In the other room, Hiccup and Toothless move to the balcony and they see Hans and everyone else attacking the snowman. "This doesn't look good." Hiccup tells Toothless who growls in agreement,

Downstairs, Elsa and Heather go to the doors to see what's happening when the Duke Of Weaslton's men spot Elsa and fo after her .

"Come on, follow me!" Heather asks of Elsa and she does.

"There She is!" One of them say as they spot the two of them running up the stairs and follows after them.

Heather runs into what she thought was the right room but doesn't see Windshear or Hiccup anywhere. "This castle is a serious maze." Heather mumbles to herself when they reach them and they're holding crossbows.

"We got her." One says as they start aiming at her.

Heather steps in front of Elsa knowing they're after her and takes out her ax. "You want her, you get through me first." Heather states as he shoots and a shield of ice suddenly appears and stops the arrow.

Heather looks and sees Elsa is just as surprised as she was when they keep trying to shoot them.

"Stay away!" Elsa warns and sends another wave of ice at them when a purple blast fires and hits them.

Elsa and Heather look at the doorway to see Hiccup and Toothless. "Hope were not too late." He says as Windshear uses her tail and wraps it around one of the men and throws him at his friend, knocking them both out.

"Thanks for that." Elsa tells the two of them.

"Come on, let's get you home before more of them come in." Heather says as Windshear comes down and Heather helps Elsa get onto the dragon.

As they take off, Hans comes in just in time to see them leave. "Return to Arendelle, fast." He tells them as they all turn back.

-

As for Kristoff's group, Olaf is sliding down the mountain as the others are riding Sven towards the castle.

"I'll meet you guys at the castle!" Olaf says as he starts drifting too far off course.

"Stay out of sight, Olaf." Kristoff tells him since a living snowman is strangest thing yet.

"I will!" Olaf promises as they split off and Olaf runs into a woman. "Hello!" He greets.

She just shrieks seeinga living snowman.

Back with Kristoff, he's going as fast as he can towards the castle when the guards notices them.

Sven stops and Kristoff carries Anna to the gates.

"Are you going to be okay?" Anna asks Kristoff.

"Don't worry about me." Kristoff says when the servants come and help Anna. "Make sure she's warm, and find prince Hans, immediately." He asks of them.

"We will, and thank you." He says and they bring Anna into the gates.

"Make sure she's safe." Kristoff asks as the doors shut on him and Sven whines as Kristoff walks away.

-

Inside the castle, Hans had beaten Elsa and the others back to the castle because Hiccup and Heather took the slow route to see if Kristoff and Anna didn't make it.

"I'm going back out to look for princess Anna." Hans informs the others,

"You cannot risk going out there again." Someone objects to his decision.

"If anything happens to her..." Hans was saying but was interrupted.

"If anything happens to the princess, you are all Arendelle has left." He tells Hans when the doors open and Anna is brought in.

"Prince Hans." Kai calls out for the prince.

"Anna!" Hans calls out seeing her and holds onto her and feels she's cold.

"Hans, you have to kiss me." Anna tells him and everyone leaves to give them some privacy.

"What happened out there?" Hans asks as he brings Anna to the couch near the fire.

"Elsa strike me with her powers." Anna explains to him.

"You said she'd never hurt you." Hans reminds her what she told him before she left.

"I was wrong." Anna tells him. "She froze my heart, and only an act of true love can save me." She explains.

"A true love's kiss." Hans realizes and smiles. "Oh, Anna. If only there was someone out there who loved you." He says before getting up and walking to the windows.

"What?" Anna asks, completely lost. "What are you doing?" She asks him.

"As thirteen in line in my own kingdom, I didn't stand a chance. I knew I would have to marry into the throne somewhere. As heir, Elsa was preferable, of course. But nobody was getting anywhere with her." Hans explains as he starts putting out the fire. "As for you, you were so desperate for love you were willing to marry me just like that. I figured after we married, I would have to stage a little accident for Elsa. But then she doomed herself, and you were dumb enough to go after her. All that's left now is to find Elsa and her helpers, kill them, and bring back summer." He states and Anna knows he's talking about Heather and Hiccup when asking about her helpers.

"You're no match for them." Anna promises him.

"No, you're no match for them." Hans corrects her. "I on the other hand, am the hero who is going to save Arendelle from destruction." He states and starts walking towards the doors.

"You won't get away with this." Anna states while trying to crawl to the doors.

"I already have." Hans tells her and locks the doors shut.

-

Kristoff and Sven were walking away from Arendelle when Sven starts whining again and runs in front of Kristoff.

"What is it, buddy?" Kristoff asks as Sven keeps snoring at him. "What's going in with you?" He asks the reindeer when all he does is snort angrily as a response.

"I don't understand you when you talk like that." Kristoff says and Sven uses his horns to pick up Kristoff. "Stop! Put me down!" He comands and Sven does.

"No, Sven. We're not going back. She's with her true love." Kristoff says before two shadows come over him and he looks to see Windshear and Toothless coming in to land with Heather, Hiccup and Elsa on their backs.

"Kristoff, good to see we caught up with you." Heather says to him.

"What are you guys doing?" Kristoff asks them.

"We were gonna ask you the same thing." Hiccup states as he gets off of Toothless. "Where's Anna?" He asks seeing she's not with them.

"We just dropped her off with Hans, she's safe." Kristoff promises them.

"Thank you." Elsa thanks The man who saved her sister when a gust of wind hits them and they look to see a snow storm forming around Arendelle.

"Elsa, this you?" Heather asks, even though she should already know the answer.

"No, this isn't me." Elsa says when they realize someone's stuck in the storm and isn't with them.

"Anna." They all say at once and all run on to their dragons or reindeer and they all start racing back to Arendelle.

-

Back at the castle, Anna is laying in the floor and watches as the ceiling starts freezing over and somebody is trying to get in.

But when the door opens, all that's visible is a carrot sticking into the key holder and Olaf comes in and sees Anna on the floor.

Olaf sees the fireplace and grabs as much wood as he could before lighting it.

Anna looks to see Olaf near the now lit fireplace and gets worried for him. "Olaf, get away from there." She warns the snowman.

"Woah. So this is heat. I love it." Olaf says while holding his hand out and it catches fire. "Ooh! But don't touch it." He warns himself and helps move Anna towards the fire.

"So, where's Hans? What happened to your kiss?" Olaf asks her.

"I was wrong about him." Anna informs Olaf. "It want true love."

"But we ran all the way here." Olaf tells her.

"Please, Olaf, you cant stay here. You'll melt." Anna begs the snowman.

"I'm not leaving until we find some other act of true love to save you." Olaf promises and drops down next to her on the floor. "Do you happen to have any ideas?" He asks Anna.

"I don't even know what Love is." Anna admits to Olaf.

"That's okay, I do." Olaf assures her. "Love is putting someone else's needs before yours. Like, you know, how Kristoff brought you back here to Hans and left you forever." He tells her and Anna just realizes something.

"Kristoff loves me?" Anna asks Olaf wondering how she missed it herself.

"Wow, you really don't know anything about love, do you?" Olaf asks as he starts melting.

"Olaf, you're melting." Anna informs him.

"Some people are worth melting for." Olaf replies happily when his entire face starts dropping and he holds it up. "Just maybe not right this second." He admits while holding his face when the wind blows the windows open.

"Don't worry, I got it." Olaf says and runs towards the windows. "We're gonna he through...oh, wait." He says as he's noticing something in the distance and breaks off an icicle from the wall and looks to see the gang heading towards them.

"It's Kristoff, Hiccup, Heather, Elsa and Sven with the dragons!" Olaf cheers seeing them all heading towards the town. "They're all heading this way." He tells Anna.

"They are?" Anna asks, happy to hear her sisters with them

"Wow! They're really moving fast." Olaf comments on their speed.

"Help me up, Olaf. Please." Anna asks him as he rushes over to him.

"No, no. You need to stay near the fire and keep warm." Olaf informs her.

"I need to get to them." Anna tells him.

"Why?" Olaf asks when realization finally struck the snowman. "Oh, I know why! There's your act of true love right there! Riding across the fjords like a valiant, pungent reindeer king!" He cheers and helps Anna stand up when the roof becomes full of ice and icicles coming out and they start running into the halls.

Once they make it to the halls, they also begin to fill up with ice and icicles. "We're trapped." Olaf says when Anna looks over to the mirror.

They then broke the window off so they can get out of the castle and slide down the soft snow and Olaf gets covered in snow.

"We made it!" Olaf says and they go back to running, looking for Kristoff. As they're walking, Olaf gets swept up in the storm.

-

The gang makes it to Arendelle and the dragons start having a hard time navigating through the storm.

"Heather, you there?" Hiccup calls out and sees that they've been separated already. "Okay, bud, just get us as far as you can." He asks of his dragon.

"I can't see through this storm." Elsa says trying to see anything that even resembles Arendelle.

"Don't worry, Toothless doesn't need to see." Hiccup says as Toothless uses echo location to see where he's going.

As for the others, Heather is trying to see through the storm and can't see anything except for Kristoff and Sven below her.

"You guys know where we're going?" Heather calls down hoping they can hear her.

"No, not really. Just trying to head straight!" Kristoff admits when Heather sees a ship about to crash into of them.

"Windshear, grab them, quick!" Heather asks her dragon and Windshear does exactly that and Kristoff sees they avoided falling into the ocean.

"Thanks, Heather." Kristoff says.

"Anytime." Heather says before putting them down and they start to faintly hear Anna.

While Hiccup and Elsa, Toothless is trying to find his way back into town when his tail inevitably freezes and they fall before being separated.

Elsa is looking around and sees a manly figure approaching she thought to be Hiccup but it's Hans.

"Elsa! You can't run from this!" Hans tells her.

Elsa tries to find a way to escape, but didn't know where to go. "I just want to make sure my sister's okay." Elsa asks of him.

"Your sister? She returned from the mountain, weak and cold. She said you froze her heart." Hans explains and Elsa is fearing the worse. "I tried to save her, but it was too late. Her skin was ice. Her hair turned white, your sister is dead. Because of you." He states to her.

Elsa can't believe what she did, we came all this way for her sister and now it's too late. She drops down to the ice and the storm clears up, revealing an unconscious Hiccup and Toothless.

Heather and Kristoff were still looking until spotted Anna across the forge. Kristoff ditches Sven and starts running towards her.

Anna looked to see Kristoff and Heather going towards them but then notices Hans drawling a sword over Elsa. Now she knows she has to help her sister, if it's the last thing she can do. She races over to her sister and as she freezes over, Hans tries killing Elsa but Anna stops him and sends him flying.

Elsa looks up to see Anna frozen. "Anna!" She screams seeing her sister dead and breaks down.

Heather and Kristoff approach them and Heather wakes up the unconscious Hiccup and he notices Anna.

"Oh, no." Hiccup mumbles seeing they were too late. Even Toothless and Windshear seemed sad by what happened.

After a minute, Anna suddenly starts defrosting and coming back to life. Everyone looked shocked to see her alive.

"Anna?" Elsa asks and pulls her sister into a hug who happily returned it. "You sacrificed yourself for me?" She asks her sister.

"I love you." Anna replies to Elsa.

"An act of true love will thaw a frozen heart." Olaf remembers what granpabbie told them.

"Love will thaw." Elsa repeats and looks at her hands before the snow starts lifting and they all end up on a boat as the ice leaves. All over the town, all the ice gets lifted and Elsa dissolved it.

"Strange world we live in." Heather comments on what just happened.

"Yeah, but it's still ours." Hiccup replies.

"Hands down, this is the best day of my life." Olaf interrupts them and starts melting. "And quite possibly, the last."

"Oh, Olaf. Hang on, little guy." Elsa says and gives him his own snow cloud.

Olaf is happy to still be alive when they look and Hans is getting back up.

Anna interrupts the rest of them before they had the chance to approach him and does it herself.

"Anna?" Hans asks seeing her alive. "But she froze your heart." He states.

"The only frozen heart around here is yours." Anna informs him and turns his back and Toothless takes it as an opportunity to shoot a light plasma blast and sends him over the edge into the ocean.

"Nice shot, Toothless." Hiccup tells his dragon before scratching his chin.

-

Afterwards , Hans was arrested and was sent home to his big brothers to deal with.

Elsa even made it clear to cut all ties with Weaseltown after the Duke tried to kill her and her friends.

"Are you ready?!" Elsa asks everyone in the court area as it seems everyone is enjoying her powers and she turns it all into an ice rink for them to use.

"I like the open gates." Anna tells Elsa as she makes her way to him.

"And were never closing them again." Elsa promises her sister.

But now the time has come, as much as Hiccup and Heather love it here in Arendelle, they need to get back to the Edge.

"I wish you guys could stay longer." Anna says as Heather is fixing Windshear's saddle after adding on a few things she thought were nice.

"Hey, if you ever want to visit us, just travel south, or ask Johann to deliver a message to get us to visit." Heather tells her and Anna quickly hugs her.

"It's nice to have a friend." Anna says and Heather feels the same way since she's only known Hiccup for the past two years. Having a friend like Anna is pretty nice.

"Just know you're always welcome back any time." Elsa says as she approaches them and scratches Windshear under the chin which she enjoys.

"Same goes for you guys and us." Hiccup says as he sees Olaf hugging Toothless' face as Toothless keeps trying to take a nibble out of the carrot.

"Hey, bud, here." Hiccup calls his dragon and passes Toothless some fish he just bought knowing Toothless is just hungry and he starts digging into the fish needing his strength for the journey home.

"Oh, I'm gonna miss you, Toothless." Olaf says as he walks off to explore summer.

"Come on, we better get going if we want to get home before nightfall." Heather tells Hiccup and mounts Windshear.

"Yeah, time for us to return home, bud." Hiccup tells Toothless and mounds his dragon and they both look back to their new friends. "Don't worry, we'll be in touch and be back." He assures them seeing they're sad to see them leave.

"One thing you should know about us; were hard to get rid of." Heather jokes as they take to the sky and make their way back to Dragons Edge.

-

The two of them make their way back home, happy to say they had a good time, if you eliminate the part where Heather and Anna almost froze forever.

"That was good thinking about what you told Elsa back then." Hiccup tells Heather.

"It was just what I tell myself every day. But if I didn't loose my family, I would've never met you. So I guess some good came out of that bad." Heather states and wouldn't change that for the world. "Gotta say, must be nice having a sibling. It's a good thing they have each other."

"I had a sister, once." Hiccup admits and Heather is surprised to hear that. "I don't like to talk about it that much. But when I was little, I had a twin sister who was died the same night that my mom did." He explains and Heather sees why he wouldn't what to talk about it that much.

"What was her name?" Heather asks him.

Hiccup thinks for a minute to trying to remember, he doesn't think of her a lot but wishes he got the chance to know her. "Hala." Hiccup answers, remembering and they continue flying home while having some fun along the way.
