In Outlander season 7 episode 6, titled “Where The Waters Meet,” a surprising twist occurs when Roger (Richard Rankin) comes face-to-face with one of his old enemies. He sees someone outside through the glass who has been polluting his and Brianna’s land as he is dancing in his kitchen and enjoying his contemporary life.
To catch the intruder in the act, Roger dashes outside, where he encounters the enigmatic person. Roger is surprised to discover that the individual is none other than William Buccleigh MacKenzie, often known as Buck, a Scottish ancestor. Graham McTavish first played the part of Buck in season 5 episode 7 “The Ballad of Roger Mac”, but Irish actor Diarmaid Murtagh is currently filling the role for season 7.
In season 5, Buck almost killed Roger by handing him over to the militia, which resulted in a traumatic episode that left Roger without a voice and suffering from flashbacks and PTSD. Naturally annoyed to see Buck, Roger soon escalates their interaction and punches him in the face.
The episode doesn’t explain how Buck got to the year 2099 or how he discovered Roger and Brianna’s house in Lallybroch. It’s unknown whether he did it on purpose or by mistake when he stepped through the time-traveling stones to follow Roger. This shocking turn of events suggests that Roger and Brianna may run into more problems dealing with Buck now, maybe diverging from the story’s original course.
The addition of Buck’s narrative twist to the TV show would usher in fresh, unforeseen plotlines that would increase excitement and fascination for both book readers and viewers learning about the story for the first time.
