Good point! In my mind that scene counts as a "flashback" in the TV show like many of Bran's other visions of the past even though it is meshed with the present. Maybe there is a better way to phrase the qualifier in the description?
Is the book that far yet though? I was under the impression that as of now Hodor's backstory is show-only. It is specified in the quiz description that this quiz is book-only.
