Speaking of Dave and Edie, Mrs. McCluskey comes home to find Toby in the chair. She asks him where he's been, but since he's a cat, he doesn't answer. However, the living room window is open again. She walks outside, as Mary Alice says that everyone does appreciate a good neighbor. We get the same montage from earlier, but when Susan helps with Lynette's groceries, she also ignores how moody Porter is -- and that he's not helping with the groceries and instead just stands there glaring; Tom delivers the mail but pretends not to notice Gaby's unhappily throwing things and/or picking them up in the messy house; Parker offers to mow the lawn, but doesn't mention how cold Orson seems. Mrs. McCluskey brings Katherine flowers. When Katherine asks why, she tells her that she needs to use her computer to find out more about Edie's husband. Mary Alice wraps it up: "But if you're not sure the man next door is as nice as he would have you believe, do everything you can to get to know him better." Including, perhaps, having him help with your light bulbs?
Next Sunday: Katherine doesn't want anyone to find out "we're doing this" (spying on Dave? Let's hope!). Lynette's marriage is in trouble. Bree has issues with Danielle, in the form of telling her son to lie. Dave gets even creepier, and Mrs. McCluskey points out to Edie that she knows nothing about him. And Gaby and Susan appear to get into a physical fight over MJ's lack of balls (the figurative kind, I'm sure).
