And from the obvious-parallel front came a gay soldier who needed brain surgery — you know, ''don't ask, don't tell'' and all that. BTW, did the Grey's Anatomy writers just get a memo that homosexuality exists? Because with all the sex on this show, never once has it come up before (despite the show's having endured a behind-the-scenes gay-slur controversy). And now suddenly we've got lesbians and closeted soldiers? Or is this part of a larger contest among all network shows to suddenly outgay each other? Because it's pretty hard to top Gossip Girl's ''gay bomb'' episode this week. Not that I'm complaining. I'm all about the very gay sweeps! Ugly Betty better ramp it up. Who knew it would ever be behind in this category?

Sloan, meanwhile, did nothing to make straight guys look good. And I say this with love, as I have no problem with man whores as a concept and kinda dig McSteamy at times. But he cannot go around saying stuff like he said to Rose, no matter how much I've irrationally decided to dislike her: ''I hate women like you,'' he snapped when she wouldn't help him smooth things over with the nurses. ''You string guys along like sex is some prize when really you're just afraid that when you give it up, he'll lose interest.'' It's like he took over insensitive-jackass duties from Alex this week. Again, though, I'm emotionally raw today, so maybe it's just me. Or maybe it was just a plot ploy, as a few scenes later, Rose was asking George for a form (in front of Meredith, no less) — the implication being, of course, that there had been some sudden intervening supply-closet action with Derek. Which we can assume was cold and mechanical and not half as good as Mer-Der sex. No panties-left-behind action, to be sure. Rose definitely doesn't seem like the kind of girl who would leave her panties behind. And to be clear, in our crazy dream world, we like girls who leave their panties behind. Though we don't like men who are mean to women who don't (theoretically) leave their panties behind. We do, however, think it's kind of funny that Alex ''forgot'' to list Lexie on his date-and-tell form — and he forgot while she was sitting right there.

Speaking of Alex, he came down with a magical fever — not too severe but just enough to get him off the heart surgery and onto babysitting duty while Cristina took over as Hahn's right hand. That, of course, led to a heart-to-heart about Burke between Cristina and Hahn — or at least a monologue in which Hahn talked at Cristina in a sort of empathetic way: ''You actually helped him with all that research,'' Hahn said. ''He didn't even mention you in the article.'' Perhaps Meredith and Derek should've taken that as some kind of cautionary tale about performing surgeries with people you've slept with, but instead they continued to stare longingly at each other while injecting viruses into people's brains. ''We're standing on the moon, Dr. Grey,'' Derek said in that cute whispery way he has. Of course, the patient kicked it, but whatever.
