Roger runs into a familiar face in Outlander season 7, episode 9, though she doesn’t seem to recognize him. The appearance of Geillis Duncan was a significant surprise in Outlander‘s mid-season premiere since she met a bloody end back in season 3. Of course, when time travel is involved, anything is possible, and this mischievous character has officially made her way back into the story. It’s unclear how much of a help or hindrance Geillis will be to Roger’s journey, but if she recognizes a fellow time traveler in Outlander season 7, it could be a problem.
