‘Outlander’ stars Sam Heughan, Caitriona Balfe & Sophie Skelton are used to time travel on-screen, but how well do they know each other’s real-life pasts? From being sent to space, to dreaming in black and white, the co-stars try to uncover the truth in "Where Is The Lie?" Watch as Caitriona can’t keep a straight face during her entire interrogation, Sophie shows off a surprising flex, and Sam reveals whether he truly went to the Canadian embassy to demand citizenship.
