The Late Show still

The Late Show with Stephen Colbert/YouTube

The brand new "Game of Thrones" Season 8 trailer left us wanting more, and thankfully, Stephen Colbert is on the case.

The "Late Show" host had Kit Harington (Jon Snow) in the hot seat during Tuesday's episode of the late-night series, and he questioned the actor about what happens in the final season of "Game of Thrones." Of course, Harington couldn't reveal much of anything. HBO is notoriously protective of the hit fantasy drama's secrets.

Colbert did manage to find a creative way to try to get information out of Harington. With a camera closely focused on the "GoT" star's face, Colbert peppered him with, er, interesting theories about how the show ends. It was a true test of Harington's poker face -- and to be honest, the actor failed pretty miserably.

Watch Colbert's interview with Harington below. Colbert starts sharing his theories around the 9:55-mark.

The final season of "Game of Thrones" premieres Sunday, April 14 at on HBO.
