Derek walks past a nurses' station and endures one more dirty look from a white lady before he blows up. He's working up a head of steam for quite the lecture about tolerance and racial harmony when Bailey -- horrified at what's about to occur -- nearly tackles him to get him to shut up. Turns out it's not racism that has been drawing all the negative attention. It's that white-bread daddy doesn't have enough sense or experience to do Zola's hair so she doesn't look like Macy Gray. (I'm sorry, but not looking like Macy Gray is important to a child. It just is!) "Do your baby's hair!" Bailey lectures, then stomps away. Derek stands there and learns a thing or two.
Meredith catches Cristina staring at Emily again, and this time she hauls her into the nearest closet. She's not sure whether Cristina is plotting a murder or a nuclear attack or what -- she's fine getting on board with either one -- but this secretive stuff is starting to freak her out. Cristina comes clean about her suspicions that Owen is having an affair. Mere asks if she or anyone else saw; of course, nobody did. But Cristina just KNOWS it. She knows it sounds crazy. She paces and tries to convince herself she's crazy. Mere rubs her pal's back and says, "I really think he's not cheating." Cristina snaps around at this and is all, "I KNOW THAT!" Being someone's Person must be exhausting.
Sloan joins Avery in the elevator and is all, "What's up? Care to partake in my creepily predatory plans to get you laid, as I am not getting any younger and living vicariously through your youthful, lean, tight body and whatever sexual exploits I can throw in front of it would be pretty great for me." Avery reiterates that he doesn't need a girlfriend. "I had a girlfriend," he says. "Now I just can't." Mark realizes Avery still loves Lexie. Bummer the way that works out, huh, asshole? Of course, Lexie not loving Avery more than Sloan is part of the problem too. That reminds me, that episode where she and Alfre Woodard yell at each other about the Twilight books was one of the best parts of the whole season, right?
Speaking of Lexie, she's bipolar-ing like crazy about this preemie business. Now she's down on it again, since it seems so hopeless, and the babies can't even tell you when they've had enough. So Alex tries to cheer her up by taking her to see their Wall O' Success. He tells the stories of the kids in these photos and how insanely tiny they were at birth. So we all get to "Awww" that Alex has a heart, and Arizona smiles in the distance, knowing she's got a real protégée on her hands. Anyway, "Some of them survive" seems to be the lesson.
