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.
