Liam Cunningham went on Conan last night to promote the upcoming season of Game of Thrones, and wouldn't you know it? He brought a clip with him! And it has Jon Snow in it.
Cunningham's Ser Davos appears to have barricaded himself in a room with Jon's body (yep, he's still dead here), Ghost, and still-loyal members of the Night's Watch. The rest of the Night's Watch, now led by Ser Alliser, is outside. When they start bashing down the door to get in, Davos pulls out Longclaw.
If you saw the red band trailer, then you know what happens next.
“I've never been much of a fighter,” Davos says. “Apologies for what you're about to see.”
