It’s time to add more fuel to the Game of Thrones fan theory fire. Jon Snow actor Kit Harrington has been spotted arriving in Belfast for the first Game of Thrones Season 6 table read. You can even see a few (admittedly blurry) photos of the actor over at Watchers on the Wall and Winter Is Coming. If these were coming from a single source, we’d have our doubts about accuracy, but it seems unlikely that several different sources would misidentify the same actor at the same time.

Some fans will jump to the conclusion that this confirms Jon Snow’s return in Season 6, but its important to remember that Charles Dance arrived in Belfast last year just to film Tywin Lannister’s funeral. If Harrington is there simply to film Jon’s funeral, it would explain why he has kept his hair long up until now.

On the other hand, this is just the latest in a series of news bits that seem to point at a role for Jon in the coming season, mostly revolving around a possible flashback scene. These include a casting call that includes a character that sounds very much like Ser Arthur “Sword of the Morning” Dayne, and a new filming location that could serve as the Tower of Joy.

Game of Thrones Season 6 will air on HBO in 2016.
