The tribes gather at Berk to discuss the dragon rider.
Thuggory ask "so, Astrid. Since when have you been Heir to Berk?"
Astrid answers "since Hiccup gave me the position of heir and I felt it was my fault that he decided to leave and I gave my shield to Stoick to engage myself to Hiccup Haddock."
Thuggory comments "do you have any leads as to who this dragon rider is that raids our tribes?"
Astrid answers "I have a guess that the rider is Hiccup. I don't have proof yet."
Thuggory comments "he has a flame sword."
Astrid raises her eyebrow at that.
Camicazi comments "I did run into Hiccup like two months ago.
Astrid ask "was he okay?"
Camicazi comments "when we met again, he ask if we were friends like someone erased his memories."
A stranger walked upto the group to see Thuggory and says "could you and Camicazi come to the forge?"
They follow the stranger to the forge.
Hiccup closes the door and windows.
Camicazi ask "who are you?"
Hiccup removed the helmet and says "I'm here to get revenge against Snotlout, Tuffnut. His sister Ruffnut and the new heir of Berk."
Thuggory ask "your new betrothed?"
Hiccup turns around and says "she called me worthless and I have no happy memories of my childhood with anyone. I only have memories of how Berk treated me horrible."
Thuggory ask "is that why you burn down their houses?"
Hiccup puts on his helmet and says "yes. Snotlout and the twins would grab me and beat me up. Astrid told me I'm not worth anything. That's why she drop me as a best friend. I took her axe for revenge."
Thuggory ask "could you train me a dragon?"
Hiccup turns around and says "right now I'm working on revenge and I don't trust you unless you promise to stop killing dragons."
Hiccup leaves the forge and walks to the forest and leaves on Toothless.
Three years later.
Hiccup raided the tribes and kept Alvin and Dagur at bay as Ryder.
Astrid walked to Stoick and says "I have a plan to bring the Ryder to justice."
Stoick ask "what is your plan?"
Astrid answers "we take the Terrible Terror to find the dragon nest and lure Ryder down from the nest and I built one of Hiccup's inventions to test."
Stoick sighs and follows Astrid to the forge to look at the invention.
Astrid pulls the machine out.
Stoick looks at the invention and ask "what does it do?"
Astrid answers "it was designed to take down Night Furies. At least the directions listed it."
Stoick ask "does it work?"
Astrid grins "I tested it yesterday and it launched a bola over two hundred feet in two seconds."
In the morning, Berk warriors grabbed rope and cuffs.
Astrid loaded the invention on the ship.
Stoick ask "are you sure about this?"
Astrid answers "yes. Once I disable the Night Fury, you need to knock out Ryder."
Stoick nods his head.
