Cuddy is, predictably, dubious when she's summoned to the rehab wing. House says erasing Derek's memories is the only way to keep him alive. "This isn't 1940," Cuddy says. I guess 1940 was a time when zapping brains to stop broken heart syndrome was a good idea? What the hell is going on? Is everyone going to find a hole behind a file cabinet and go crawling into John Malkovich's brain next? House explains the hows and whys of his crazy mad genius plan to Cuddy while we see shots of the Cottages looking on in disbelief and/or boredom. House ends by saying that electroshocking Derek's brain will erase his memories of Amy -- and everything else -- so he won't be in love with her anymore and therefore not die. And what an awesome life he'll have to look forward to, what with having no idea who anyone is, including himself. It's like dying, but you have to live through it. "Go ahead," Cuddy says. Cuddy. Cuddy! No. Don't do this. This is insanity. But House sends the Cottages on their merry way and asks Cuddy why she was so quick to accept his treatment option. He thinks Cuddy only said yes because she feels sorry for House, as if his personal problems would have any bearing on Cuddy's decisions regarding patient care. They do, actually, but they shouldn't. No, Cuddy says, House presented her with a clear and reasonable argument as to why they should do something completely insane to poor Derek, so she said yes. See? It's positive reinforcement to keep House in rehab, and the only thing it cost was some guy's mind.
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.
