Who is Jon Snow's mum? For that matter, who is Jon Snow's dad?
Who is Jon Snow's mum? It's one of the biggest secrets in the Game of Thrones universe. Five books and four seasons of TV into George R.R. Martin's A Song of Ice and Fire, and the author has dropped several hints about Snow's lineage, but hasn't revealed anything definite about who is parents really are.
Fortunately (or unfortunately if you feel like this kind of thing ruins the fun), one fan theory has become very popular in online GoT circles, and after watching this video we're inclined to think it's probably correct. Of course, Martin, being a very savvy plugged-in author, could always come up with something else with the express purpose of subverting the theory, but this video makes a lot of sense. Watch it at your own peril because it feels like a super major spoiler.
