Ever since Jon Snow (Kit Harington) was stabbed to death "for the Watch" last season on Game of Thrones, fans have been fervently hoping he was not really dead. There were, seriously, so many theories about this. Turns out, those fan theories—or, at least, one of them—might be true. HBO just released a poster for Season 6 of the fantasy show and the only face on it is that of Jon Snow. He looks bloodied and broken, but he’s there. Is he back for real? Is he a ghost? Is this all a cruel joke being played on us by HBO? Twitter is already, well, atwitter over what this could mean. We'll find out for sure when the show returns in April.
