Back from break, everyone's back in the conference room and Foreman's taking a moment to stare CTB and PS down. I would have stared them down, too, except it would have been their retreating backsides I was looking at as I kicked them out of the hospital for defying my orders like that. Kumar tries to be cute and suggests writing Casey's new symptom on the Whiteboard. Foreman says he can't, since they don't know if it's a symptom or the result of CTB and PS giving her steroids at the same time as the interferon. Apparently, this can fry one's immune system. WOW, nice going CTB and PS. If they really thought it was lupus, they should've disconnected her from the interferon. If they weren't sure enough to do that, then they shouldn't have treated for the lupus at all. Treating her for both at the same time and frying her immune system is not what House would have done. CTB defends herself by saying they did consult an immunologist (who looked at the chart for all of one second and is currently working as an ER doctor and not an immunologist), and Foreman immediately figures out who she's talking about. He's pissed to hear that Cameron told them to undermine him, but 13 says they should get back to the medicine for now and stop watching Foreman "spank" CTB and PS for their mistake. Hey, guys, do you think maybe 13 is into spanking? Or maybe her abusive dad used to spank her. Oh, wait, I don't care.
