Tom is at Julia's bedside. Evelyn is not. Maybe she has an open relationship with her parents and is hanging out with another couple and letting them read her bedtime stories and bake her cookies while her real parents are too busy with their problems to give her everything she needs. None of the latest treatments worked for Julia, so they still don't know what ails her. House takes a second to note that Tom brought a bouquet of lilacs to his wife's bedside. Hadley somehow knows that they're from his garden, which causes House to think about how his mother also used to grow lilacs in her garden, but stopped because they attracted lots of bees and R. Lee Ermey apparently hates the gentle and hardworking honeybee because he was always a jerk. Here comes Epiphany Face! House says they ruled out something called Henoch-Schönlein purpura because there was no respiratory infection that causes it. But apparently bee stings can also, in rare cases, cause HSP. Hadley's not so sure, saying there should also be a rash. House and the Cottages enter Julia's room to check for one, since apparently no one bothered to look at Julia's body before this moment. She admits that she was stung by a bee a month ago, and House starts looking around for the rash while explaining that Julia has HSP, which is also called "systemic vasculitis." Hooray for vasculitis! It causes lesions and inflammation all over the body, which explains all of Julia's symptoms. A quick external exam of Julia reveals no rash, so House says it's time to "check [her] holes." Cut to Tom not looking all that bothered about this, because, you know, he's okay with other men touching his wife. Julia opens her mouth to reveal a rash on the roof of her mouth. House is disappointed that this means he won't get to check her sexier parts, or as he refers to it "get kinky." Do you guys remember when he found a tick inside an underaged girl's vagina? Do you think he thought of that as being "kinky" then? Yuck. Now that they know what's wrong with Julia, they can treat it and she'll be just fine. Julia is so relieved that she tells her husband she loves him. 90% of the time. House can't leave things that happy, so he reminds them that Julia sleeps with other men and Tom sucks with money on his way out. Let us also mention that Julia can't get stung by a bee without almost dying. Wimp.
