It's fair to say Jon Snow has been quite coy about the information he's willing to reveal during any TV appearances these days.
And for good reason too as revealing Game of Thrones spoilers is something that would be punishable by death if we lived in Westeros. But there is one question we want to know the answer to and that involves the fate of Harrington's character, Jon Snow.
Being a bit of a Game of Thrones fan himself, Jonathan Ross decided he wanted to get to the bottom of it and had a novel way of getting some answers out of Kit. Cue the reveal of his lie detector machine, The Stone of Truth.
Ok we'll admit, as interrogation gizmos go, this one wouldn't be Jack Bauer's tool of choice but it's still a pretty funny segment all in all.
