If Teri Hatcher has a plan to leave "Desperate Housewives", next week's episode could be the exit story. Susan uses her kidney ailment to garner special treatment in public places. The new condition may gain her some privileges but when the real thing kicked in, Susan is at a very dangerous state. Talking about the episode, Vanessa Williams who plays Renee dished out, "Well Susan is still working on her Kidney issue because she has to get a donor and she's on dialysis. We're about to shoot an episode where I try to make her use her ailment to get us into a fashionable restaurant in town and it kind of backfires."
