The amount of unanswered questions is really bothering Hiccup. Radley seems convinced this isn't the afterlife, yet no one apparently knows where they really are or how they got here or how to get back. So he lets out a frustrated sigh and tries to think.

"Okay so there are gods here. Or... a god? Just one? Who or what is it?"

Of course, being a Viking, he's always been told stories of the Norse gods.
