The Game of Thrones cast members are pretty much immune to spoiler extraction tactics, but that doesn't stop late-night hosts from the trying their hardest anyways. On Wednesday, Jimmy Kimmel attempted to get some answers from Isaac Hempstead-Wright, who plays Bran Stark on the HBO drama. After Wright admitted he once spilled a major GoT secret during a math class, Kimmel asked about a popular fan theory: Is Bran actually the Night King? Wright tried to play coy and said, "I think he's the Three-Eyed Raven, who is definitely on the side of the living." Welp, that's a dispute against the leader of the undead if I've ever heard one. Watch the clip above to hear Wright's full answer, and find out how he perfected Bran's creepy stare.
