Season Four, Episode Seven: A Foggy Day In London Town

Our heros make way for the British capital, and everyone has a rather jolly good time for a short while. But political intrigue and personal vendettas catch up with Ross and Demelza, and a slimy fellow MP leads to familiar familial tensions between our romantic leads. Horace plays a key role in a lovely moment, though, which helps resolve some of the sore feelings.
