Episode Title:
Darkest Night.
Episode Description:
Stoick is attacked in one of his routine border checks. He is rescued by the A team but is left in a comatose state as a result of his injuries. Hiccup is pressured to take up the temporary role of being chief in Stoick's absence, but Hiccup blames himself, believing that if he had never shot down Toothless in the first place, his father never would have been injured. Going from this, the others begin theorizing how different their lives and Berk would be had things gone differently. Later, an injured Heather and Windshear return from Vanaheim with dire news.
