Sexy Mimi offers Bree some tea for her walk of shame, and Bree gets really aggressive with her in return, all butter-wouldn't-melt and so-I-heard-you-fucked-my-poolboy. Mimi is offended, because she never slept with Keith, and Bree's like, "That was just a cunning test to see how you reacted to my wild imaginings." Instead of slapping her across the face, Mimi's like, "Well played, you old bat." They drink their tea and Mimi's like, "He never stops talking about you. Hey, I'm going to leave you alone with our mail so you can get super suspicious and read our mail and discover some troubling facts." Bree's like, "One step ahead of you. Could you hand me that teapot? I've got some letters to steam open."
Keith's on probation for assault, apparently, so instead of talking to him about that like a grownup, Bree heads on over to Renee's house to chat and gossip and generally involve Renee in the relationship she stole from Renee. But since Renee is awesome, she only says one or two mean things before hand-waving the whole thing away: Apparently, the scuttlebutt she got from the bartender -- at that place where Bree put her dress on backwards, speaking of senile dementia -- is that Keith only got nicked because he was defending his girlfriend.
Best line in the episode so far is Renee, on the concept of vetting one's one-night stands: "Don't wanna end up handcuffed to my bed for three days... Again..." And also, let's not throw stones in the crazy house, considering Bree's already sabotaged her own sprinkler system and activated her army of little people in order to get this guy in the first place. Comforted by the Keith part -- and breezily unaware of the serious nature of her own problems -- Bree's like, "Thanks for calling me a 'bony old white lady' and giving me this news, friend." Renee then snottily counsels her to start a fight to see if Keith slugs her, which is such a killer end line that you almost feel bad for Bree having to come up with a rejoinder: "Whoever left you handcuffed to the bed for three days? He has my respect."
