This isn't the first religious patient House has treated; you have to wonder at this point if he isn't collecting them. I'd say he's trying to kill the faith one believer at a time, but if he is, it hasn't been going very well (before tonight he was, what, 0 for 3?). But "Unfaithful" might be a new one—a priest whose already stopped following God even before he walks in the door. Our PoTW, Father Danny, was accused of molesting a teenager a few years back, and while he claims he's innocent, the church has shuttled him from town to town ever since. So he doesn't have much goodwill left towards Jesus, which makes things especially awkward when Jesus comes by to say hello.
Danny checks himself into the ER, and House grabs the case; not because he thinks it's worthy (although surprise, surprise—it is), but because he's looking for a way to screw around with Foreman and Thirteen. While the priest chokes down hospital food and earns the contempt of Taub (has there been a patient this season he's liked?), House lays down an ultimatum: either Foreteen splits up, one of them quits, or he's gonna start a'firin'. Then there's the usual rigmarole that happens whenever House starts playing games. Foreteen debates the nature of the game, decide to bluff him out, he calls their bluff by firing Foreman, and then Thirteen and Foreman's relationship collapse into a bitter heap of acrimony, with both of them still on the job, but neither exactly happy about it.
Actually, they are happy—turns out it was all a con to get House off their backs, and the two are still very much in spit-swapping mode. It's too bad, really. I initially dug the chemistry between Epps and Wilde, because it served as a distraction for the painfully misguided House/Cuddy foolishness, and because I thought it might develop into something interesting. I was hella wrong, no two ways about it; whatever the faults in the writing, Hugh Laurie and Lisa Edelstein are old pros, and I still like them even when I don't like the direction they're headed. With Foreman and Thirteen, things aren't so bright. The most entertaining parts with them in "Unfaithful" were when they appeared to be fighting; given the clunky, too-fast development of their supposed love, it was nice to see that love crash and burn in a sensible way. Knowing it was all a trick means that we'll be treated to more of them next week, and I'm not happy about that.
Also not hugely happy about the brief re-emergence of Chuddy, but at least it was fairly low-key. Cuddy's having a Jewish naming ceremony for her baby, she invites House along, and the games begin—House questions her motives for inviting him, then he questions Wilson, Wilson gives up the game so House realizes that Cuddy's just doing it to keep him away, but it turns out she actually wants him there, and so on. All very rote. House has been fairly well defanged at this point; even Laurie seemed bored kvetching over his boss's supposed "hypocrisy" (has Cuddy's Jewishness been mentioned before?). It did all lead to a nice montage at the end, with House noodling on the piano while Cuddy had her party and Foreteen gave in to their jungle fever. I don't think for a minute that seeing the grumpy doctor sweep the frazzled administrator in his arms would be anything but terrible, but so long as they keep dangling just out of each other's reach, I don't mind quite so much.
