Molly's up next. Lee's eyes are barely clear of the eyedrop fluid before she's crying about how he lied to her about their financial situation. She can't give him a break, can she? First, she's all bent out of shape because she thinks he cheated on her, then she finds out he wasn't cheating on her at all and is still mad. Meanwhile, Lee's been punished enough for all of this seeing as how HE CAN'T MOVE and all. Lee defends himself by saying the last time he told her business was slow, she got migraines every day. Molly doesn't seem to remember that, though, so she says "how could you do that to me?" and cries and leaves the room because she probably has a migraine. Lee begs her not to go, but if I were him I'd be relieved she was gone. Unless it means that there's now no one around to put the eye drops in.
Taub walks into House's office and informs him that he wants to keep his job, and thinks his computer idea should be enough for that. House disagrees, only giving credit for that to whoever invented the computer that could read minds in the first place. House wants to know why Taub is fighting for his job now and not before, when he first found out it wasn't secure. Taub says the work they do terrifies him, but "overcoming that is the only way I can matter." I guess he realized that never in all his time as a plastic surgeon did he feel like he did when he saw the cursor move. But it's still not enough for House, who says that Kumar was the one who found the factory and thought of the cadmium diagnosis. "Maybe you don't matter," he says. He lets Taub know that this conversation is finished by turning to his computer.
It's Hadley's turn with the patient. She completely skirts responsibility by closing his eyes so he can sleep. Lee mentions his sore eye again, and Hadley sees something that warrants the introduction of a stain into Lee's eye that she warns is going to sting. I'm just impressed that they have specific eye stains in every hospital room like that. Lee gets a dose of the stain dropped into his right eye and yes, it stings. After she gets the dye nice and in there, she checks his eye out under a black light and finds ulcerative keratitis. That rules out cadmium poisoning, much to everyone's chagrin. With the possible exception of Taub, cause he gets another chance to matter. And Lee's, because he can't actually chagrin right now.
