Hahn runs into Callie in the hall and the two act really awkward and make excuses about being soooo busy lately. Seriously, it seems they picked this up like, the day after last season's finale and just ignored the complete change of season. They both go and ask Bailey if there's anything else and she explains that there is nothing, and that she's charting because she gave up the clinic and the Chief stole her trauma case. The two other women seem even more at a loss for a response than they were with each other, so Callie takes off as Bailey hands Hahn Billy's x-rays to review. She notes that it's a hemopericardium and after a moment, proudly launches into a textbook definition of what that means. (And yet, it still involves a whole bunch of words I don't know and I don't really get it. Don't worry, it's not going to matter soon.) (Sorry, Billy.) Bailey tells Hahn to quit trying to teach her as Mark walks up and asks if they want to know how he teaches. They don't, but he answers, "Like a guru." I definitely missed Mark. "I gently guide them along the path to truth and wisdom." Lexie runs up to George and starts to stammer that she heard "something" earlier, but he cuts her off to ask Sloane to help Sarabeth. Illustrating his guru-like ways, he asks George if he's a, "Special Moron from the Isle of Complete and Utter Morons?" Clearly even Hahn recognizes this as bad teaching and when that's the case, you know you're atrocious. Everyone leaves but not before Lexie can declare, "He's an ass." And the grass is green. Did you just catch on to that?

Cristina's pissed that their only patients are women in ball gowns, but Mere admires them for both trying to save Billy's life and also for being happy after being with their husbands for years. She thinks if they can do it, she can do it. Cristina opens her mouth and seems about to finally say something to Mere about her relationship but she's cut off by Derek wondering who paged him. Mere tells him both Bailey and Izzie, and advises to see Bailey first since she has the limo driver. That out of the way, she asks Derek if he wants to move in, and he says yes. With over an hour and a half left of this premiere, who wants to bet it won't really be that easy? Derek asks if she's ready and she tells him, "I'm leaning into the fear to get a happy ending." He doesn't know what it means, but he'll take it. They turn the corner to hear the Chief swear and declare Billy dead. He stomps out while having almost a little passive-aggressive tantrum, telling Mere to cancel the OR they booked.
