We're less than a week away from the return of Game of Thrones and the cast is still spending most evenings hitting the talk show circuit, having to carefully avoid revealing any secrets about the events of season eight. The latest to face the test was Nikolaj Coster-Waldau, aka Jaime Lannister, who paid a visit to Jimmy Kimmel Live on Tuesday night, only to be immediately hounded with fan theories. Is Bran the Night King? Will Arya kill Cersei? Will Daenerys turn into a dragon? Coster-Waldau does a pretty good job of hiding his reactions to each theory (despite referring to himself as a "terrible liar") but he does have one he personally loves, and that's the theory that a savior named Bielsa will make an appearance in the final season and make everything right. There's just one problem with his plan, and if you're a soccer fan, you might know what it is. Watch the video to find out for yourself, and to find out why Coster-Waldau believes that the ending of Game of Thrones is totally "Sad-isfying."
