Klaus (Robert Sheehan), along with Number Five, is one of the only members of the Umbrella Academy to have time travelled before the start of season two. In the first season, after stealing a time-travelling briefcase from assassins, Klaus ends up taking part in the Vietnam War. Now that he's back in the '60s, it seems he's taking a different route based on the psychedelic hands seen in his glasses. This, along with his fabulous wardrobe, have us thinking he's very much into the idea of "make love, not war" and avoiding the trauma from his first time in the 1960s.
