Avery and Reed are hanging out, making up a two-person, "We're In Love With Our Merger Buddy" club. When Avery sings Cristina's praises from the surgery, Reed warns him that she's out of his league, so Avery just counters by looking at a sleeping, shirtless Alex and asking if he himself is really the hopeless one. Should one really fall asleep with a preemie casually in their arms? Or any baby, for that matter? I'm guessing no. But then again, there's that torso on full view. Reed berates herself for her feelings on account of Alex being married and an asshole.
Bailey comes in and asks Alex if he was there all night, then tries to dismiss him to get some rest. In addition to everything else, please someone get that tiny baby a hat! She can't waste energy trying to regulate her own temperature at only 30 weeks! Alex is a bit embarrassed as he assures Bailey that he's fine, but she's impressed by his caring, and tells him he'd be good in pediatrics since he gets invested. It's an interesting statement, given that I thought she decided earlier this season that being personally invested was a bad thing. But regardless, she compliments him on his good instincts and repeats that he'd be good in peds. I do appreciate that they finally came back to this point after all the time he spent working with Addison, when he also showed promise with the kiddos.
Cristina is working on Hillary's chart while Hillary chats on the phone, and incredibly she asks her friend for drugs right there, commenting how lame it is that they have her on such a small dose of morphine. Cristina can be reckless but even this is too much, and she grabs the phone and threatens the girl on the other end before hanging up. Hillary is totally indignant, but Cristina just calls her out on how she thinks she can do and handle anything. Hillary rolls her eyes but Cristina reminds her that in fact she fell off a roof because she was high and then almost died in surgery because her system was taxed by her drug use. (First time we've heard that, but it makes for a good argument.) Cristina points out that this in fact makes her an idiot, and informs her that the only reason she's alive is because she's lucky. Cristina pauses a second, as if she's going to give herself credit for Hillary's survival, but she seems to have learned something and doesn't. She then tells Hillary to grow up, though by Hillary's sulking I'm sure she'll do nothing of the sort.
Arizona watches from the walkway as Jennings and Richard deliver the news to the Andersons, and they fall apart. Afterward, she walks to Callie's where she opens the door... to a hoard of people yelling "Surprise!" and blowing plastic horns. She finally falls apart, and as she starts to cry Mark gives a knowing nod about the evil surprise party. Arizona can't speak and eventually walks out, and a horrified Callie takes off her party hat and runs after her. Mark can't help but drop a, "Told ya," and Lexie doesn't contradict him.
