During the five years, Rose and Firewind done most of the time trying to locate Alexis and her evil dragon trappers. 

Apparently, that Rose discovered her dragon is a species that no one has ever met before, she dubbed her dragon species, "Titan Nightwings", a more advanced version of a Night Fury. 

She knew that would cause a surprising discovery for any viking, and so, she kept the species as a total secret. 

She also knew that being with Firewind would cause some trouble, as that most vikings still has the type of thinking that dragons are fireous creatures and not able to understand that they are not dangerous as they intend to be. 

As she was flying, Firewind's ears twitched as she must've sensed something was completely wrong. 

"What is it, Firewind?" Rose asked, wondering why her dragon was so concerned about something. 

As they landed, it was appeared to be someone was on the island, and there was footprints of a familiar species. It was a footprints of a Nightfury. Rose seems shocked as Firewind looks at his rider for instruction of what to do. 

"It looks like trouble. Can you use your Echo Location, girl?" Rose asked. The dragon did just as she instructed. 

Both dragon and girl followed the way as to their surprise to see a dark Night Fury all muzzled up! 

"What in the name of Thor?!?" She exclaimed, worried about the dragon she has seen in front of her.

She couldn't believe it! As she was staring in awe, her dragon nudged her to take action. 

"Firewind, Plasma blast those chains! We need to find his rider. I think I know who would do this... I don't like it. " Rose commanded. She did as instructed as the black Night Fury seems to be in awe of Firewind.

"We can talk about it later, boy. Right now, let's go find your Rider and get out of here!" I said, in worried, stern expression.

As the group continues on their way to find the dragon's companion, they heard a call. It felt unfamiliar to her, but not to the night fury. He ran as both dragon trainer and dragon followed the dragon's lead. 

As they did, Rose saw the rider. He seems relieved of his dragon's safety, as that he was in awe of seeing her and her dragon. 

"A dragon rider who owns a Night Fury? This is a surprise." He said, as the dragons went into protective mode on their riders. 

There was laughter booming in the air, as Rose knew exactly who it was, the person that raided Berk twenty years ago. 

"Well, well, this is a mid-surprise. I never expected my trap to work so well. " Alexis said, appearing from the shadows with her wild dragons surrounding them. 

Hiccup pulls out his inferno, to take some action, as Rose said, "Well, we meet again at last, Alexis. You seemed busy since I last saw you. You been extremely busy, it was hard to track you, but my search has reached it's end." 

"Indeed I had. Besides, I am more interested in those dragons you have." She said, as Hiccup said, furious rage, "You wouldn't dare of hurting my dragon. Toothless, plasma blast!" 

The dragon did as he was told, as the two of them flew to escape. "Get them!" Alexis demanded, as the two vikings tried to shake them off. 

"What we do? We can't possibly shake them off!" Hiccup said, as that Rose looked at every direction. 

"Down there, there is a gap that those dragons wouldn't go through!" She pointed as Hiccup followed her lead, which it works as it would expected. 

As the dragons landed, both riders exchanged looks at each other. Hiccup was nervous as he said to her, "You were amazing. Coming with an idea that quickly, it sort of like you knew the way of the dragons so easily then I could." 

Rose smiled, "Thanks for the compliment, stranger.  So, what is your name anyway?" 

Hiccup realized how rude he was, as he rubbed his head, "I am such a idiot for not introducing myself. 

My name is Hiccup Horredous Haddock the third, but everyone calls me Hiccup. That night fury with your dragon, he is Toothless. He's my best friend." 

Hearing his name, Rose couldn't believe it. She never inspected that she is meeting her little brother again after all this time. 

The last time that she ever saw of him was when Alexis raided their home, when he was an infant. 

Hiccup titled his head, in concern of her well-being. "Is everything all right? Was it something I've said?"

The rider step back for a moment, as she thought to herself, "I can't believe it. This is my little brother now, five years later?

He's completely different! Why at all places he and dragon came here? C'mon, Rose Rosalie Haddock, you're an adult now, as well he is. I have to rip the bandage off now or else I would regret it for the rest of my life!

She took a deep breath as she said, "I know it's all too sudden for you to grasp, Hiccup, but this isn't the first time we meet. 

The last time I ever saw you was when you were little. I never imagined of how our reunion would be like this.

Don't you see, Hiccup? We're more alike than you think. My name is Rose Rosalie Haddock. I'm your older sister." 

Hiccup was taken aback of what Rose had said. 

"Um, what you mean by that? I don't have any siblings as long I can remember! How could you be my sister?" 

Rose said, "Hiccup, you have to believe me. I will tell you everything."
