Chase prepares Nadia for her dialysis. He mentions her sister, and Nadia says he must think she's being too hard on Elena. Chase says he understands that grudges can be difficult to get past, but Nadia says this isn't a grudge -- it's "common sense." Elena has hurt Nadia more than she's helped her, so Nadia is better off without her. She claims that because she has a perfect memory, she doesn't "edit" her memories like everyone else does to keep from remembering the painful truth. I don't know; it seems to me like Nadia is forgetting one very big part of her relationship with her sister: that she's her sister, and she loves her. And that has nothing to do with whether or not you have a perfect memory and can keep a mental tally of pros and cons. It might make it more difficult to forgive someone when you can remember every thing she said or did to you and how awful it made you feel, but it shouldn't make it impossible. Especially since Nadia should be just as good at remembering the good times as she is the bad ones. And finally, she's had this memory since puberty, so why hasn't she learned how to deal with forgiving people or accepted that not everyone can remember things as well as she does? This is like The Flash challenging mere mortals to a foot race and then getting angry when they aren't very good competition. Chase says if Nadia can never forgive anyone then her life must be pretty lonely. Nadia claims that she does forgive people, but only if they've done more good things for her than bad. And then she stops being able to breathe, so there goes her friendly relationship with her lungs.

Foreman brings Taub to his home. Taub is surprised by Foreman's personal style, saying he always figured Foreman's place would have shag carpeting and a "Mod Squad vibe." Oh, it's probably best that we don't bring up the names of shitty movies this show's cast members were in. I'm sure Peter Jacobson has a few clunkers on his résumé, too. Foreman scowls and tells Taub he's only allowed in the dining room and Marcus's old room, as Marcus moved out to work for their uncle in Florida. Sounds like Foreman and his brother didn't have a very happy reunion after all. Also, I guess Orlando Jones had better things to do than collect a paycheck for appearing on this show again. I can't imagine what those things are, but good for him. Foreman says Taub is only allowed to study and sleep from now until the exam. Taub doesn't think this sounds like fun and has no desire to abide by Foreman's rules. Foreman says if Taub fails his test the second time and House makes Foreman's life miserable, Foreman will kill Taub. Honestly, if Taub loses his job at PPTH because he failed a test twice in a row after everything else he's blown, I think Taub will kill himself and save Foreman the trouble.
