Sometimes a teaser for a highly anticipated TV show or movie is just that: A tease. In the short preview of Game of Thrones' sixth season, HBO seems largely to be toying with fans. After the viewers are informed that the past has already been written, Bran Stark's (Isaac Hempstead Wright) voice comes on to say that "they have no idea what's going to happen" — and for the teaser's purposes, "they" presumably means "us." After a brief montage of death, the 40-second video mostly features Jon Snow (Kit Harington), who (SPOILER!) died last season. That seems to suggest he's coming back in Season 6 — in some shape or form — despite Harington's insistence that Snow is dead. You can decide for yourself in the clip below.
