Viggo paces outside the room with Toothless and Windshear guarding him so he doesn't try anything.

"I don't trust the guy." Astrid states.

"You know, he'd actually be pretty fun to hang with." Tuffnut says and they all look to him. "I mean, if he weren't trying to kill us all the time."

"You gotta love the way he talks." Ruffnut agrees with him. "Hiccup, I'm afraid our time together has come to an end. I must now kill you, if you have no objections."

"Yeah, like he's not gonna have objections." Tuffnut replies. "Then he'll go, all of your Dragon Riders must also go, with my sincerest apologies."

"I'm with Astrid. This is all just a big game to him." Heather agrees.

"Ryker is coming to try and wipe us out along with his brother. Are we really gonna take chances with Viggo?" Fishlegs asks.

"You guys are right. I got this." Hiccup says and they bring Viggo into a cell.

"Hiccup, you must reconsider." Viggo asks of him.

"Viggo, I'm sorry. There's too much bad blood for us to trust you'll not do anything but try to, well...you know." Hiccup states.

"And the Dragon Eye's return, it did nothing to assuage your concerns?" Viggo asks.

"Not enough." Heather tells him.

"Ryker will attack this island with my Shellfire dragon. I'm afraid he won't stop until all of you are, well...you know." Viggo promises.

"That's encouraging as always, Viggo." Hiccup says.

"You see, that's just it. I could be of considerable assistance in helping you defend your home if you would allow me." Viggo asks of them.

"We'll take that under advisement." Heather promises when the twins come in with Astrid close behind.

"They're here. Well, I mean not here, but very soon." Tuffnut tells them. "I think we might need to start getting ready."

"Translation, Astrid?" Hiccup asks.

"Dragon Hunters. Multiple ships headed this way." Astrid tells them.

"Come on." Hiccup tells Heather as they get their dragons. "Make sure he doesn't go anywhere." He tells the twins and they fly off.

-

"All right, gang, we have until dawn. They'll be in range by then." Hiccup tells the group.

"Hiccup, I've had a thought. Now follow me on this." Snotlout asks of him. "I don't know about you guys, but I'm not completely attached to this place, right? Let it burn to the ground."

The two of them look to him in anger to that he's suggesting they let the place they've called home for over three years just die.

"I mean, it's been fun. Great views. But is it worth dying for? That's what you have to ask yourself." Snotlout tells them. "All right, lets take a vote."

"Snotlout, we're not letting our home just die." Heather states to him, angry he's suggesting that.

"And if we don't stop them here, they're going to go for Berk next." Hiccup adds. "We have to make our stand here and do whatever it takes to stop them. Astrid, you and Stormfly cover the backside of the edge. Snotlout, you and Hookfang get the Gronckle Iron walls up on the huts. Fishlegs, you and the twins be prepared for the first wave of ships." He tells them when the twins come up to them.

"Hey, Hey! There's no crying in Maces Talons!" Tuffnut tells them still on the one liner. "What do you think? It's already got the Viggo stamp of approval."

"That's awesome." Hiccup says sarcastically. "Ruff, Tuff, you're with Fishlegs."

"Don't worry your pretty little head. We're on it." Ruffnut says.

"I'm not worried." Heather says.

"Talking to Hiccup." Ruffnut tells her. "You'll have it before you can say ultimate destruction, my friend." She says and they leave.

-

as morning rises, so does the Shell Fire near the edge as they start firing at them.

"Incoming!" Snotlout warns as they see the attack coming in.

"Everyone to their huts. We have to wait out the initial attack." Hiccup tells them and they take to the skies to their huts.

Hiccup and Heather go into theirs and close the doors.

The twins make it to theirs and finds chicken.

"So,what was wrong with your hut?" Ruffnut asks Snotlout.

"I was so busy with everyone else's, I forgot about mine." He admits.

They wait it out and see most of the Edge has taken a lot of damage after the attack quiets down.

"Okay, I don't know about any of you, It there's no way I'm sitting through that again." Snotlout promises. "We have dragons. You have an arsenal of them. We should be out there sinking those ships."

"The fire isn't coming from the ships, it's coming from the Shell Fire." Hiccup reminds him.

"I hate to be the one to say I told you so, but.." Viggo says as he shows up.

"How did you get out?" Hiccup asks him.

"My friend, Snotlout was good enough to allow me to use the facilities." Viggo explains and gives Snotlout a shoulder hug as he smiles nervously.

"He did, did he?" Heather asks looking at him.

"What? He scares me." Snotlout tells them. "Besides, when you gotta go, you gotta go. And who knows that better than me?'

"Hiccup, you must allow me to assist you, for the sake of us all." Viggo begs of him. "The Shell Fire's range is over a mile. Ryker is using ships. My ships to be exact, to protect it."

"Then we need to get past the ships." Heather says when another hit comes in.

"And we better do it quickly." Hiccup agrees and turns to the twins. "Ruff, Tuff? You're up."

"We're on it." The twins say and run off with Fishlegs and Astrid to do their jobs.

"Hey, what about me?" Snotlout asks.

"Why don't you look after your new best friend." Hiccup offers.

"Where's the fun in that?" Snotlout asks.

"It's not supposed to be fun!" Hiccup says as he leaves to find Heather before looking back. "And I don't care how scary he is, do not let him out of your site again." He warns Snotlout and leaves.

-

Hiccup and Heather fly out and see there's a lot of ships protecting the Shell Fire.

"We need to slow them down a little and move on." Hiccup tells Astrid and Heather. "If they fire on us, we fire back."

They start avoiding the arrows and Shellfire blasts and make their way through the ships and Heather goes in and cuts one of their ships as more Shellfire attacks come in and they make their way closer to it.

"Are you guys seeing this?" Hiccup asks as they see the Hunters are beating the dragon with boulders. "Of course it wouldn't fire on its own."

"And we can't take them out without endangering the dragon." Heather adds.

"I'm pretty sure that was their plan." Astrid breaks to them as the Shellfire shoots more blasts at the Edge.

"Split up." Hiccup tells them and they start flying around the ships and Ryker is enjoying the show.

"There's no way to control it without hurting it." Hiccup sees.

"We might not have a choice." Astrid breaks to him.

"No, there's got to be another way." Hiccup says when they see Snotlout heading towards them.

"Aren't you suppose to be watching Viggo?" Heather asks him.

"Is that the stables on fire?" Hiccup adds.

"You said don't let him out no matter what." Snotlout reminds them.

"Snotlout, use your brain!" Hiccup states.

"Good Thor, you're so material." Snotlout tells him. "Viggo taught me that. I don't know what it means."

"Go, we'll be fine." Heather tells Hiccup.

"Let's hope this isn't the biggest mistake of our lives, bud." Hiccup tells Toothless as they fly off to the stalls.

-

Across the island, the Tripple Stryke and several other sea are fighting off the Dragon Hunters to defend their home.

-

Hiccup and Toothless fly in and find Viggo inside his cell.

"Hiccup, you came all the way back to rescue me." Viggo sees while he's coughing from the smoke. "I'm honored."

"Yeah, don't be." Hiccup says as he helps him up and out of the stalls. "If I left you here to die, it would make me no better than you.""

"Well, you'll be glad you returned." Viggo says as he regains his breath. "I can help, if you will allow me."

"How? How can you help?" Hiccup asks.

"I can advise you on defeating and stopping my brother and the Shellfire." Viggo promises.

"You got that all figured out, have you?"

"As luck would have it, I do."

Hiccup thinks and allows to see what he has. And if it goes sideways, he can always just push him off mid flight.

-

"Okay, I'm confused. You said keep him in his cell. You can't toy with my emotions like this, Hiccup. I'm too fragile right now." Snotlout says as they all join back together in the clubhouse.

"He's right. Mostly." Astrid agrees.

"If Viggo can help figure out how to stop this attack-" Hiccup as saying when Heather interrupts.

"What if he can't? Or won't? Or a part of the plan?" She asks him.

"Then, we walk into it." Hiccup tells her. "Viggo and I are going to take this thing down." He says and leaves them behind and they fly off.

-

They fly out towards the Shellfire and Ryker, ready to end this war and battle.

"You know, theses word of a tournament. To be hosted by the Tribe of the Whispering Trees." Viggo tells Hiccup as they have a moment alone.

"Is that right?" Hiccup asks, uninterested.

"Maces and Talons? The winner, apparently, receives a life size game set. Made of solid gold." Viggo tells him.

"Oh, lucky him."

"Poor, dear Hiccup. Relationships can be complicated. Am I right?" Viggo asks him and Hiccup looks at him surprised. "I see the ring on your hand." He says and Hiccup sees his hand and ring out in the open. "And while I can't put myself directly in your shoes, I can mostly surely empathize with your situation."

"You can, huh?" Hiccup is still uninterested in what he's saying.

"Absolutely. Having someone you love this much in the field of battle with you. It can certainly cloud the mind, impair judgement. Make even the simplest decisions vexing."

"You know what's vexing, Viggo? Is why you're rambling on trying to get inside my head. I would think that, by now, you'd have given up." Hiccup states to him. "I'm focused, I'm clear, decisive. What I am not is your friend, your ally, your Maces and Talons buddy, okay? So let's leave our personal lives out of this and get down to business."

"I'm only trying to help." Viggo mumble.

"Well, if you want to help, why don't you tell me where we're going and what we're doing?" Hiccup asks as they see nothing as they fly further from the Edge.

"Stop, Dragon." Viggo asks Toothless and Hiccup has him stop.

"What's going on? There's nothing but ocean." Hiccup says.

Viggo pulls out a sword behind Hiccup's back as he doesn't notice. "Yes. So, it would appear."

"I wouldn't do that if I were you!" Heather warns and Viggo looks to see she followed them.

Hiccup then turns and sees the sword. "Whoa! Whoa! What the Thor?"

"I'm afraid you may have misinterpreted the situation, dear Heather." Viggo tells Heather.

"Nah, I think I've interpreted it pretty well." Heather says. "Drop it."

"Exactly what I planed to do all along." Viggo says and drops the sword into the water and they see the Shellfire raise up to them.

Back at the Edge, the dragons have started fighting as they were trained to do and take down the ships with Fishlegs leading them, as the other riders go up and see another Tidal Dragon rise up.

The twins try to avoid a catapult of arrows and dive into the water with Snotlout. When they did, the Shellfire sees them and they take back to the skies.

Astrid goes in and gets knocked off Stormfly.

"Time to finish them off. Do it!" Ryker tells the Shellfire and they start beating the dragon and it gets ready to fire when another dragon rises up and fight it.

"What was that?" Tuffnut asks.

"That, my friend, was a Submaripper." Ruffnut informs her brother.

"Where'd that come from? And why is it helping us?" Snotlout asks.

Hiccup and Heather come flying in and watch the fight.

"So the dagger was to stir up the water and cause our Submaripper to surface?" Hiccup asks.

"Precisely." Viggo confirms.

"How'd you know we had one and it would react this way?" Hiccup asks.

"Hiccup. The Submaripper is the natural and hated enemy of the Shellfire. And I learned you had one when I was building the Shellfire. It was a little fact I kept in my tunic for a day just like this."

"The Dragon Eye." Hiccup sees. "All right, the Shellfire is tied up with the Submaripper. This may be our chance to get the rest of the ships out of here."

The two of them go in and start to destroy the last of the ships as the two Tidal dragons fight it off.

"Viggo, I need to drop you on the beach. You're slowing us down." Hiccup tells him.

"Pity. I was going to enjoy watching Ryker go down with the ship." Ryker admits as they land and let him off. "We may be adversaries, Hiccup, but my respect for you is beyond what I could possibly put to words."

Toothless snarls at the man and they take to the sky.

On their way, they see the Tripple Striker is fighting off the ships along with the others.

"Look at that. Their training is coming in handy." Hiccup says and flies off to help the others.

-

The others finally finish the last of the ships and see the Shellfire and Submaripper fight until the ship on its back gets pushed off and Ryker along with it as he screams his brother's name and gets sucked into a whirlpool made by the Submaripper.

"O.M.Thor. The Submaripper. Submaripper-ama." Tuffnut says watching the destruction.

"Hate the smell. Love the dragon." Ruffnut agrees as the Shellfire leaves and the Submaripper starts eating up the last of the Hunters and boats.

-

Hiccup and Toothless land near the volcano and look at the fight and see happy.

"It looks like the nightmare is finally over, bud." Hiccup tells Toothless.

"Are you sure about that, Hiccup?" Viggo asks and he looks to see he's holding Heather with her axe being healed to her throat.

"Viggo. Let me guess. You want the Dragon Eye in exchange for Heather." Hiccup guesses, ready to end this man by himself if he needs to.

"It sounds much colder when you say it like that. But, yes." Viggo says and Hiccup looks mad at him. "While I do appreciate your assistance in putting my brother in his rightful place, I must insist to where it belongs. With me."

Hiccup take sthe Dragon Eye out of the saddle and has an idea to be rid of everything.

"Hiccup, don't give it to him." Heather tells him.

"Come now. Are you willing going to sacrifice you future...all the wonderful years you have ahead of you for that?" Viggo asks and Hiccup comes to terms with what to do.

"Well, I guess when you put it that way, no, I'm not!" Hiccup agrees and throws the eye towards the volcano and Viggo chases it until it falls into the lava.

Viggo looks angry and turns to Hiccup when the ground underneath him collapsed and he starts falling.

"No! Hiccup!" Viggo shouts and Hiccup runs over to save him only to see a splash in the lava follows by his screams and he sees he's gone.

"It didn't have to end this way." Hiccup says, sorry for how it ended.

Heather walks up to him and pulls him into a hug, Happy they're both okay. "You okay?"

"Yeah, I'm fine." Hiccup says and returns the hug,

"It's finally over. It is over, right?" Heather asks of him.

"Viggo and Ryker are gone, meaning there's no leader for the Hunters and there's nothing left of the Hunters themselves." Hiccup says and breaks the hug and they see their dragons are happy to see the other is okay and start caressing their faces against each other lovingly.

"Yeah, they're definitely together." Heather sees.

"So...is it time I learn what's going on with you recently?" Hiccup asks her, wanting to know what's going on with her.

Heather looks to him with a smile and is ready to tell him. "Hiccup, when we were on Berk, I paid Gothie a visit as I wasn't feeling...myself recently. Let's just say that us getting married isn't the biggest thing that's going to be happening." She says and places Hiccup's hand on her stomach.

Hiccup is confused when he starts putting the pieces together. "Wait, Heather, you're-"

"Pregnant." Heather finishes for him with a smile on her face.

Hiccup looks to her and just smiles before picking her up, spinning around before placing her down and kisses her for a minute with a big smile on his face. "This...changes..."

"Everything." Heather finishes when they turn and see the others also heard the news and are in shock.

-

What the two don't know, even after their wedding that they had held in Arendelle since they wanted it somewhere nice, and after the others returned to Berk, there was still someone out there they didn't know about.

The one who hired Viggo to hunt the dragons for his army.

Drago Bludvist.
