Brideshead Revisited - Season 1 Episode 6

Charles returns to Paris to continue his art studies and is surprised with a visit from Rex Mottram. It would seem that he and Sebastian had stopped in Paris enroute to a sanatorium in Zurich but Sebastian has stolen his cash and disappeared, much as he did with Mr. Samgrass during the tour of the Middle East. Charles recounts the tale, learned many years later, of Rex and Julia's relationship. Much to Lady Marchmain's objection, Rex and Julia are engaged and Rex agrees to take instruction in the Roman Catholic faith. Rex very much wants a big society wedding but only a short time before the event, Bridey learns that that Rex was once married and is now divorced. Not realizing the impediment this causes Roman Catholics, Rex has some difficulty understanding why they can't just go ahead. Julia stands her ground however and insists they will be married one way or another.
