No spoilers, promise!
Just want to point out that if you blinked the other night you might have missed Chris Stapleton's appearance on Game of Thrones!
He played a Wildling-turned-White-Walker, and there was a brief shot of him on the ground as Jon Snow attempts to charge the Night King outside of Winterfell.
Watch the clip that his wife posted online which is below. Once again, very brief but I'm sure Chris had a blast!
