Viewing this episode in an H.264 encode is arguably the best way to experience the show’s distinct visual grading.
In the 1743 timeline, this episode is where Randall’s sadism becomes fully clinical. He doesn't just want to hurt Jamie—he wants to break Claire by making her watch. He has Jamie stripped and chained, then brings Claire into the cell. He tells her: "You’re going to watch him die, and then you’re going to watch him burn." The tension is unbearable.
