Callie sings to Mark and her frighteningly tiny baby in the natal ward. Then she fades to the background while Lexie and Avery have an awkward conversation about where he's staying tonight. He tells her he can't be the guy who waits around for the girl who's still in love with someone else. She simply looks him in the face, takes his hand, and says, "Let's go home." I love these two as a couple, but I see dark, Mark-shaped clouds ahead.
Callie's still waiting on a guitar solo, so we peek in on Cristina and Altman. Cristina begins to discuss another case, but Altman cuts right to the chase: "I can't teach you anymore." Cristina is shocked, but Altman persists: "If you refuse to learn, if you won't listen, I can't teach you." And then she stomps out. Really not a good week for Dr. Altman.Back to the song, and I'll tell you this: when Callie gets to the last few moments of the song, when she's belting it out like the goddamn diva she is, it kind of all comes together. Singing Callie thrusts her hands out to grab Real Callie's legs, and Real Callie starts to wake up. Singing Callie fades away as Real Callie opens her eyes. She tries to form a word, which gets Arizona's attention, and at first it seems like there might be some brain damage keeping her from forming actual words. But she pushes through her grogginess and makes out the one she's been waiting to say all episode: "Yes." Arizona's like, "What?" Callie: "I'll marry you." Just as soon as she gets Arizona a list of the songs they're absolutely not having at their wedding.
