In the end, Cameron just recruits Foreman to help hold Doug steady while she does the LP. I think he's only helping her to stick it to House and to try to find out what she's doing back at her old stomping grounds. Pettiness and curiosity have overcome Foreman's traditional lazy selfishness. Cameron tries to claim that she's just trying to see how House is doing following Kumar's suicide, but Foreman sees right through that, saying that even if the suicide did mess House up, it wouldn't change his already negative outlook on life, and misery only makes his diagnostic skills better. Foreman's guess is that Cameron wants her old job back now that there's an opening, which is fine with Foreman since he needs someone to help him stand up to House. Also, he can copy her journal articles when he isn't trying to infect her with a mystery illness while also convincing himself that being a Cottage is a sound lifelong career goal. I see right through you, Foreman. He then gets all concerned about the damage Cameron is doing to her relationship with Chase, as if he ever cared about that before. Maybe now that he is also involved with a co-worker, he has slightly more empathy. But I doubt it. Cameron decides that the LP is impossible to do with Doug's hiccups even with the mighty Foreman holding him down and goes to get some drug that will stop them.
Chase finds Cuddy in the Clinic and asks about the newly-opened position on House's team. Cuddy thinks he's interested in it, but he suspects Cameron's the interested one. And he's worried enough to risk looking like an unprofessional jealous boyfriend to tattle on Cameron to the Dean of Medicine. Fortunately for him, Cuddy is just as unprofessional and jealous, so she tells Chase that Cameron hasn't expressed an interest in getting back on House's team to her. "Do you think Cameron's in love with House?" Chase asks his boss. "That is a ridiculous question. She's in love with you," his boss says. "Are you in love with House?" Chase asks. Cuddy says that's an even more ridiculous question. Chase says he asked two questions and got zero answers. He also got way too personal with his boss, so, great effort all the way around, Chase!
