As Lexie wheels Billy down the hall, she sees Derek and April talking in the next room. Billy catches this and tells her she has to fight back. She gripes that April is just finding her footing but Billy counters that she's found it in Lexie's back. When she asks why he cares, he says that he likes her. He's an incredibly good-natured burglar; it looks like a golf club to the spine hasn't hurt his sunny disposition. He tells Lexie to find April's open window, or her key in a fake rock. So it seems the real lesson here is that fake rocks look fake, and not to hide your keys in one. Well, that's our lesson, while Lexie's is to find April's weakness. Lexie tries to defend that she's not a criminal like he is, so he basically warns her straight up that April is making her look like an idiot.
Derek goes to visit his healing wife, and it's a nice touch that he actually closes the blinds so that they can visit without being in a fishbowl. She wants to know if he talked to any of "them," and he's amused by her attitude and kisses her. She won't be deterred, and tells him she needs to know how Cristina is doing, since she was cardio deprived and depressed earlier. He asks if both of them are in a dark and twisty place, and kisses her again. Mere says that they are, and it's yet another nice sign that they finally let this couple just be a couple that Derek knows that if Cristina is in a bad place, Mere will be there with her in solidarity. And it's a nice nod to Mere's growth in general that she can be there and fully commiserate without actually falling into a wrist-slashing place of her own.
Alex goes back to his patient's room to find Hunt and Reed there, and Hunt reams him out for not noticing that his patient had neurological symptoms. Alex stammers while Reed smirks at him, and Hunt gives Reed the credit for noticing and diagnosing cartotic stenosis. He tells her to book an OR, and when Frank's daughter asks about his other surgery Hunt tells her, without sugarcoating anything, that he has a 90% blockage in his artery and that's the first thing they need to take care of, which is a lot to digest but Reed will be there to keep them updated. Wow, I hope she keeps up the stellar job she's been doing so far. As Hunt walks out Alex lamely tries to tell him since he diagnosed the tumor it's his surgery. Hunt just tells him that he can scrub in on the tumor surgery, then, but for now he's just there to help Reed. I can't decide if Hunt really hasn't picked up on the hospital-wise animosity between the two sets of doctors or if he's just ignoring it as they are all adults and it's not his job to be a babysitter and/or mediator. Alex then growls at Reed that she didn't put the symptoms in the chart, but Reed just questions innocently, "Oh, I didn't? Hmmm." The daughter narrows her eyes at them, but still says nothing.
