Race To The Edge: Wings Of War Parts 1 & 2

In these episodes, Hiccup and Astrid show some affection to each other.

Part One

When Hiccup is concerned about defeating the Dragon Flyers, Astrid optimistically says that he'll come up with something. When asked how she knows that, she states that it is "Because Hiccup Haddock is the wisest, most talented and brave Dragon Trainer on Earth. And he always comes up with it."

At the end of the episode, Astrid finds Hiccup alone on a sea stack, where she asks him about his problems. After a short conversation, Hiccup accuses Astrid of sounding just like his father. He then prepares to leave to find another solution. When Astrid asks him about what would happen if he can't, Hiccup doesn't answer and takes off on Toothless.

Part Two

Hiccup is relieved to see Astrid again at the end of the battle and tells her that she had him worried.
