Kumar, who is looking more and more like the New Chase in every episode he actually gets screen time (which is, like, two episodes), gets right down to business and tosses out a few diagnoses. House, on the other hand, doesn't care that at any moment and without warning, the math teacher could fall down dead and talks about Wilson, wondering what he did for House. I think the bigger question is, what did House ever do for Wilson? Ignoring this, Taub guesses the organs could have had some kind of infection that the screening process missed and lay dormant for five years, but Kumar says for all of those different parts of the body to be affected like that it would have to be five different infections. The chances of five infections slipping through the screening process are pretty slim. At this point, even Hadley is more professional than House, who interrupts his whining about Wilson to say that whatever affected the victims, it didn't come from the organs themselves, which were not affected, so it must have come from the donor's blood. The good news about that is that since corneal transplants are bloodless, the math teacher (I think Hadley calls her Apple? Oh, hold on -- one website is calling her Apple. Apple must have been so pissed when Gwyneth Paltrow stole her unique name and gave it to her daughter) will be fine. As for the old guy, Hadley apparently couldn't care less. Foreman asks her if she's confident enough in her theory to send Apple home. "I guess we could wait 'til we figure out what's wrong with Frank," Hadley mutters, refusing to actually admit she's wrong and has no faith in her abilities, which is good because she doesn't really have any.
