When Isabel and Jamie return from Peebles, Cat finds out that they have slept together and is furious with Isabel. As Isabel sits at home feeling guilty, Tom comes to visit and says that he doesn't think Angie loves him. Isabel tells him to end the engagement, and, if Angie refuses to give up the chance at Tom's fortune, to pay her off now. Later, Mimi announces that Tom and Angie have split up, but says that Angie refused to take any money. However, after Mimi and Joe return to Texas, someone sets fire to Tom's Dallas house (although Tom is unharmed).
