You're going through your post-Game of Thrones week minding your own business casually reading the odd fan theory when all of a sudden. the internet pulls "hey there, Catelyn Stark is a zombie and she was in Sunday's episode" on you.

You can watch the moment in the video above, but there's also a handy GIF:
Fans of George R.R. Martin's book series will remember that Catelyn Stark came back as a zombie, a plot twist that the show seemed to move away from. So this could either be a brief homage, an indication of zombie-like things to come, or literally nothing. Probably nothing. Right?
