Everyone has family trouble on Wisteria Lane, which should come as no surprise. Danielle finally brings Benjamin to visit Bree and Orson. Unfortunately, Danielle and her husband's "nutty liberal politics" irk Bree, who finds out not only that Benjamin's a vegetarian, but also that Danielle's going to home-school him. She sneaks him a hotdog (or two), and when he throws up later, Danielle's pissed. She and her family leave, and now it's Orson's turn to be mad at Bree: for ruining what might have been their only chance to have Benjamin in their lives again. Orson has somehow become the most sympathetic character this season. Gaby sells her car and buys a "piece of crap" from Andrew. He refuses to budge on the price or on fixing it or anything else, but Gaby finally gets her mojo back and at least gets him to pay for the broken radiator. She does this thanks to a talk with Susan, whom she first gets in a physical fight with (it's wacky!) because Gaby's daughter's been bullying Susan's son.

But the most important storylines involve Creepy Dave, who's manipulating everyone he comes into contact with. First there's Katherine and Mrs. McCluskey, who continue to investigate him, and even take Edie out to dinner to ask her what she really knows about her husband. They plant the seed of suspicion so that Edie puts Dave on the spot in front of everyone, asking him where he went to college. When he calls her out for it later, she blames Mrs. McCluskey for making her suspicious, and he plants the seed of Mrs. McCluskey starting to have dementia, just like his "poor grandmother." It's ominous and -- is it possible I'm concerned about the safety of Mrs. McCluskey? Naaaah.

Dave's also there to cause mischief for Tom and Lynette. Lynette wants Tom to clean their garage, which means getting rid of the equipment of all of his deferred dreams: mountain climbing, speaking German, beer brewing, and being in a band. Except that instead of getting rid of his bass, he starts a jam band in the garage with -- you guessed it: Dave! Lynette doesn't like it a bit, so she sabotages by destroying his guitar. But Dave swoops in with a replacement bass, and gives Lynette a lesson in handling her husband. It's as creepy as everything else Dave does, and especially so because Lynette listens and we close the episode with a Mary Alice voiceover that tells us Dave's the kind of bully who gets people to do things they're not even aware they're doing (and it shows Lynette presenting Tom with the guitar). I'm going to go out on a limb and say that Dave's going to cause a lot more trouble before he's through.
