Chase checks out the husband, Esteban, who wants to know if House is checking out his wife, Marina, right now. Chase says Marina is with Cameron. Esteban protests that they had permission to see House and went through a lot to see him. I'm not exactly sure why they had to raft it to New Jersey if they had permission, but, whatever. Chase says that House doesn't care what they did to see him. "That's who you risked your life to see," Chase says, "and you made the right choice."
Cameron prepares Marina for the MRI of DOOOM! She tries to engage Marina in conversation by saying "it must have been difficult on the boat." No, Cameron, I'm sure it was really easy what with the having to be rescued by the Coast Guard and all. It looked like a fucking picnic. Marina says that her husband can "fix anything" -- except the boat's motor, which conked out after the first night, and Marina. But he was sure that House could fix her. As for the motor, I'm guessing it's going to some boat repairman who doesn't play by the rules or treat people well, but always gets results. Marina says Esteban refuses to "worry or pray," because he says that if you don't worry, you don't need prayer.
Chase runs down Esteban's symptoms with House for three seconds, then says that Foreman's not going to leave PPTH -- he doesn't want to, and House doesn't want him to. Chase predicts that House will cave to keep him, just like he caved to keep Cameron. "Foreman's not as easy as Cameron," House says, "but, of course, who is?" The camera pans over to the heretofore unseen conference table, where Cameron is sitting with the perfect pissed-off expression on her face. "I'm in the room," she says. BRILLIANT! Things like this are why I love this show.
The conversation is cut short when Foreman enters the room and says that Marina has MS. It explains all her symptoms, although Chase points out that some of those symptoms were crossed off because they were consistent with Esteban's. Foreman shrugs that off, saying they might have the same symptoms for different reasons. Chase says they might as well just put all of Marina's symptoms back on the Whiteboard if they're going to go with that. Foreman says they can do something "productive" and put Marina on interferon to see if she improves. If she does, it's MS. Yeah, that treatment-to-prove-a-diagnosis technique works really well. Just ask Lupe. Except that you can't, because she's DEAD. Much to Chase's obvious disgust, House gives Foreman a "well done" and sends him off to give Marina some interferon. Chase is super-jealous that Foreman gets praise while he gets punched in the face, but House just tells him to go do his job. Meanwhile, House seems to be trying to hack into Foreman's email account and see what he thought was so funny.
