One of the reasons that Jackson is so bent out of shape is that while he's assisting the Chief with his own clinical trial, all that currently entails is caring for little white mice. He's not thrilled to have "cleaning mouse poop" on his current to-do list and can barely disguise that from Richard. Richard doesn't seem to notice, though -- maybe he is distracted by Jackson's hair, which he appears to be growing out a little. I am a little leery of this look but will reserve judgment for a couple of episodes to see how it comes along.
The adorable orphan baby from Alex's slideshow, Zola, is crying when Derek goes in to see her. A woman from the orphanage hands her over to Derek, who explains how she might have some fluid buildup from her condition and that repositioning of her might make her more comfortable; just like that, Zola stops crying and McKenna, the orphanage worker, almost falls over from shock since Zola basically hasn't stopped crying since she got to the orphanage four months earlier. Derek just grins and coos at her, already smitten, and seriously, something in my brain just misfired on account of all of this preciousness. My feelings on Derek are well documented but if we see him sweetly coo at this baby much longer, I might take back anything bad I've ever said about him in the last five seasons. I'm not exaggerating, that's how powerful this baby's (and McDreamy's) cuteness are right now. See? I just called him McDreamy. What is happening to me??
Teddy, Arizona, Cristina and Lexie are at their patient's bedside along with the kid's older brother, Sefu. Teddy explains that they are going to repair the boy's heart while Mark constructs a new sternum for him. The boy says something to his brother who translates that his brother just asked: if he dies, can they delay telling the family so that he doesn't ruin his sister's birthday? Oh come on, now you're just blatantly pulling on our heartstrings, people. Arizona sits down on the bed and assures the boy that they will take really good care of him, and he won't ruin his sister's birthday. It's unclear if his serious face is because he doesn't necessarily believe that, or if it's because he doesn't understand English and is trying to decipher what Arizona just said by her tone. Teddy then opens the boy's gown so that they can see his chest, and the doctors gape to see the fully detailed outline of his heart beating just under his skin.
Having come the closest anyone could to seeing someone's heart beating outside of their body, Cristina marches down to Owen to try and get him to fix the Teddy situation. Owen is struggling with an unruly patient and Cristina jams a needle of B52 in the guy so that he'll calm down and more importantly, she can rant uninterrupted. It seems she was in the room because she's on Arizona's service but she points out that this just puts her tantalizingly close to this amazing cardiac case, but not actually able to work on it when it's time for surgery. As Owen starts to staple the now-dazed guy's head shut, he finally caves and tells Cristina that she has to apologize. Cristina asks him what she should apologize for: having better judgment than Teddy and saving Callie's life? It's arrogant, but she's totally matter-of-fact about it because she believes it with every fiber of her being. Okay, so she gets a little grandiose when she declares that there will be a wedding tomorrow because of her. Even Owen's patient, in his dreamy drug haze, knows this isn't a good apology. Owen points out that she asked him what to do, and he gave her an answer, implying that the rest is now up to her.
