In this behind-the-scenes featurette, the cast and crew of How to Train Your Dragon 2 talk about Hiccup's (voiced by Jay Baruchel) reunion with his long-lost mother, Valka (voiced by Cate Blanchett).

Five years after Hiccup and Toothless successfully united dragons and vikings on the island of Berk, the two friends find themselves fighting to protect the peace after they discover a secret ice cave that is home to hundreds of new wild dragons and the mysterious Dragon Rider.

How to Train Your Dragon 2 opens on June 13.
