Re: A Song of Ice and Fire/Game of Thrones Spoiler-Filled Discussion
They've already cast an actress to play one of the Children of the Forest this year, so that's almost certainly part of what it means. I imagine some reference to Dany, her dragons, and her human "children" is also involved. Possibly they'll do the chaining of the dragons in this year's finale.
Egg, I dreamed I was old.
