Three years ago. You and Hiccup went separate ways. Dragon hunters had taken your dragon and you wanted him back. Hiccup needed to go back to Berk. He kissed you one last time and told you to be safe. And then he flew away on Toothless. You hoped you would see him again.

Three years later...

Hiccup missed you. So did the others. He was in his usual spot when Astrid ran up to him. Astrid: "Hiccup! There's someone flying towards us!" He gets up and looks at the sky. Sure enough, there's a dragon with a rider on it. The dragon looks eerily familiar but he can recognize it. They run down to the area the dragon lands on. Tuffnut and Ruffnut are staring in shock at something while Snotlout is cheering. Hiccup: "Everyone move!" They quickly move and what he sees next shocks him.
