As the riders were silent, Trent seems to be lost for words. In front of him was Rose, the person he thought was lost those years ago. 

Rose knew how hard for him to adapt this new revelation, thanks to Hiccup. 

Astrid, however was very concerned about his well-being, as she demands for an answer. "All right, who in the name of Thor are you?!?" 

Hiccup said, trying to calm her down, "Take it easy, m'lady. This is no ordinary stranger for Trent if you're that worried. 

Trent, I know it's a lot to grasp, we just reunited, and she knows everything." He informs the young teen which bewildered him. 

"Wait a second. Did you guys actually met one other?!?  Wait, Rose, I have tons of unanswered questions! How you alive, why you didn't come back home, and does this have to do with that night you left?" 

Rose seems to bothered with the bombarded questions, as she looks at the distance. "This place isn't the place for answers. " 

"You're right. How about the Sanctuary?" Hiccup suggest, but then he changes his mindset. "No, that would be too easy. Alexis might follow us there. Follow me." 

In Hiccup's lead, Trent and Rose was amazed by the isle that he led them to. "Welcome to Dragon's Edge." 

"Dragon's Edge?" She was unfamiliar with that name, as Hiccup reassures her, "Firewind and the other dragons are welcome here. It's old now, it used to be our stop ground from home. It's from one of the adventures us dragon riders had." 

When the group finally landed on Dragon's Edge, it was clear for the young riders to give them some personal distance between them as that they had lot to discuss about. Hiccup pulls Astrid from behind, which left the viking startled and confused. 

"Rose, I think you can take the lead from here. I'm sure that Trent has a lot of questions that need answers to, and Astrid and I will not intervene." 

"Hiccup, wait a second!" Astrid said, as her boyfriend pushed her to give his sister the explanations to her childhood friend.

The two vikings leave the two teens alone, as Astrid was outraged by the way Hiccup was acting. 

"Hic, what was that about? Trent doesn't know her personally! She's a stranger, and you brought her to Dragon's Edge without hesitation! What were you thinking?!?"

Hiccup puts his hand behind his head, as that he kinda knew that she would ask, as that it still makes him worried of how she would react. 

"You're not going to mad if I tell you? " He asked her as Astrid was puzzled by that. "Why would i, is it something important you didn't mention to me?" 

He sighs, "I didn't know about any of this until I met her. She is actually my older sister. Rose Roslyn Haddock. " 

Astrid gasps as Hiccup turns away, "I was just a baby when she disappeared, after all these years I didn't know I had a sister. 

Trent and Rose were childhood friends and that I had a feeling that her disappearance affected him emotionally and mentally. 

When I was little, Alexis raided the village and threaten to kill me. Rose was taken by Firewind, a Titan Nightwing, who protected her from her attacks. 

In some way, I understand Firewind, because it was the same thing with Toothless. I think it was because she was frighten as Rose was that night. She saw through her eyes, and she saw herself." 

Astrid asked, "Do you think they would make up? Because of that raid?" 

Hiccup shrugged, "Honestly, I don't know. I hope they do, because I know they deep down, they want to. " 

Trent and Rose stood side by side, as that it seems uncanny that they would be together after a long time. 

"I guess that you have some questions about that night have you?" She asked. He nods, "Yeah, I just can't believe it. You have time to answer all of my questions." 

"Ok, I deserve it. " Rose said, "It's hard to believe."
