Kit Harington stopped by “Late Night with Seth Meyers” on Monday night to talk about Season 5 of “Game of Thrones” and to also ruin a dinner party.

Meyers invited Jon Snow to his dinner party in a funny segment where the brother of the Night’s Watch shared a little too much around a table of Meyers’ friends. Revealing that your ex-girlfriend shot you in the chest with arrows or the dreary fate of the Seven Kingdoms if the White Walkers climb the Wall is not exactly casual small talk.

Jon Snow also recounted the entire history of “Game of Thrones” at the dinner party, Red Wedding, incest and all. He comes this close to revealing who his mother is, but we don’t get that lucky.

“Game of Thrones” returns on Sunday, April 12 at 9:00 p.m. ET on HBO.
