Cate is gathering the courage to e-mail an old boyfriend Matt. Jim remembers telling Cate to stay away from the guy. Then C.J. takes the liberty of sending the e-mail. Soon after that, Cate declares that she's taking some time off from taking care of everything and locks herself inside her room. Suddenly, there is a knock on her window. It's Matt (played, thanks to brilliant casting, by none other than Katey Sagal's old cast-mate Ed O'Neill from Married with Children)!
