Cameron tells Derek that after the "treatment" he'll still be able to perform basic tasks such as "walking, talking, and tying [his] shoes." Oh, well, as long as he still knows how to tie his shoes I guess he hasn't lost anything after all. She continues that only Derek's "experiential memories" will be affected, which means he won't remember Amy or his childhood or his mad firefightin' skillz, which, based on those burns over half of his body, won't be too much of a loss. Cameron asks Derek if he's okay with forgetting about his fucking PARENTS along with the rest of his life except for shoe-tying and here is where the sane and logical person would say he'd rather tell his brother and Amy about his feelings and then work through them like everyone else who's experienced unrequited love than have his entire mind erased. In fact, you'd think he'd rather die than have his mind erased. Also, won't the broken heart syndrome stop when the testosterone starts taking effect and making him stoic and manly again? And why am I even asking questions about this when it clearly doesn't make any sense? Of course Derek would rather fry his brain than make family dinners awkward.
It's arts and crafts time at rehab, and House is working on molding clay into a lower intestine with ulcerative colitis. It looks like a plain old lower intestine though, so I guess he hasn't added the ulcerative colitis yet. Can't wait to see the finished product, though! Shitter makes a surprise visit after Cuddy apparently insisted that he see House in rehab for himself. He says he wasn't expecting House to go this far and applauds him for making an effort, before getting all smirky and asking if House expects him to go talk to the DA now. Because if so, House is going to be very disappointed. And he is. He asks Shitter what he's supposed to do if his words mean nothing and his actions mean nothing. Shitter just shrugs in the most infuriating way ever and leaves. House calls out after him: "you son of a bitch!" and everyone in rehab turns and gets ready for awesomeness. "What about your words, your actions?" House asks. Shitter said he was doing all this so House would clean up his act, and then when he finally does (I guess being in rehab for three days is supposed to be enough), it's still not enough because all Shitter really wanted to do in the first place is"bitch-slap" a guy who wouldn't kiss his cop ass. Shitter says he's learned not to trust addicts due to some tragic backstory of his we'll never explore so who cares. Even addicts' actions lie, Shitter says.
