Did Actor Maisie Williams Accidentally Drop a Major Spoiler for Game of Thrones Final Season?!

I'm hoping this was an April Fools prank or the entire planet just heard one of the biggest death spoilers on television before it officially airs.

If it were a prank, Maisie played it well because the audience reacted with shock, whispers and silence.
