'Desperate Housewives' Sneak Peek: Bree and Karl Caught

One of the several sneak peeks released for the upcoming episode of "Desperate Housewives" reveals that Bree and Karl's affair is caught by one of their friends. A slight opening in the motel curtain allows Susan to peek inside the room and discover the long-kept secret. The synopsis for the episode titled "Would I Think of Suicide?" says that Bree and Susan are literally up in arms with one another.

Meanwhile, Lynette's pregnancy causes a rift with Gaby. In another clip, Carlos is forcing Lynette out of her job by replacing her with a guy and transfers her to Florida. Lynette refuses to budge and therefore is given an office inside a closet space.
