Foreman takes blood from Nate, although not without first shooting him up with a sedative before Nate can make too many gay jokes. Enid sort of has a problem with Foreman unnecessarily knocking her son out, although I think that's mostly jealousy.
Cameron can't take the elevator without having her ride hijacked by a nervous Wilson, who tells her that he's about to be fired by Cuddy for sabotaging Foreman's interview. Cameron sees right through his pathetic lie and even more pathetic acting job and figures out that Wilson was trying to get Cameron to admit that she was the one who sabotaged the interview. Wilson grouses that Cameron would've fallen for it three years ago. Wilson says that he's just using Cuddy's logic that whoever screwed up the interview did it because she cares for House. Which leaves THE WEIRD NIGHT JANITOR WHO WEARS HIS PANTS BACKWARDS! Bring him in for questioning, I say, since Cameron denies having anything to do with it, unconvincingly saying she doesn't care about House. Then she does some smell-the-fart acting, which I guess is supposed to mean "thinking about who could have sabotaged the interview."
Cameron and Chase test Nate's blood. Cameron takes advantage of the opportunity to ask Chase if he's the one who screwed up Foreman's interview, and did so just because he doesn't like Foreman. Chase reacts with outrage and hurt that Cameron would think so low of him. And yet, he still gives Cameron his weekly reminder that he likes her and wants to see more of her, albeit through gritted teeth. "See you next Tuesday!" Cameron says cheerfully. Ha! I bet she's been waiting all week to try that out.
