Previously on Grey's Anatomy: Season 1. Also, Dr. McDreamy's wife shows up and ruins everything for Meredith; George clocks Alex for giving him the syph via Nurse Olivia; Chief Webber has brain surgery; and Cristina's pregnant with Burke's baby.
We open at the Emerald City Bar across from the hospital. Mere throws back shot after shot of tequila as we hear her voice-over, "To be a good surgeon, you have to think like a surgeon. Emotions are messy. Tuck them neatly away, and step into a clean, sterile room where the procedure is simple: cut, suture, and close." Joe the Bartender tells her she looks familiar, and asks if she's been there before. Mere: "Once. That worked out really well." Joe says it's got to be one of two things: her boss is giving her hell, or her boyfriend is. Mere says it's both, since her boss is her boyfriend, but that's not as big a problem as the fact that her boyfriend has a wife. Joe gives her a shot on the house for that one. MereVO: "But sometimes, we're faced with a cut that won't heal. A cut that rips its stitches." Mere takes her shot, and we cut to...
...McDreamy, icily asking his wife, "Addison, what are you doing here?" Addison blithely avoids the question, and comments on his longer, dreamier hair. McDreamy asks again what she's doing there. Addison: "What are YOU doing here? You left everything -- your house, your wife, your practice. You had a life. And now you have a girlfriend in Seattle. She seems...sweet." Aw, man, Kate Walsh is so fabulously beautiful and evil here that I can't even hate her. McDreamy says if she came out here to try to win him back, she can forget it. Addison assures him she's just here for work -- the Chief asked her to come. McDreamy can't believe he wasn't informed. Addison leans in close to McDreamy and hotly tells him she really does like his new hairstyle. Yow!
Izzie asks Alex to let her see his new George-given black eye. Alex tries to act all hard about it, and says if he had been ready, he would have kicked George's ass. Izzie's all, "Well, why didn't you, big shot?" Alex: "You kiddin'? I'm riding plastics all the way to the bank." I don't even know what that means. Well, I do, but it's still stupid. Izzie tells Alex he had it coming. Alex responds that George punches like his sister. Izzie totally shuts him down with, "Oh, so by that definition, you got beat up by a girl." Heh.
Cut to George entering Joe's bar to cheers and applause. Cristina tells everyone that George knocked Alex down in one punch. George tries to pretend he's not impressed with himself, but he totally is. They sit down next to Mere at the bar. George orders a beer, and Mere asks them to play a game of "Guess Whose Life Sucks The Most." Cristina challenges her, saying she'll definitely win. Mere goes first: "Derek's married." George spit-takes his beer, and Cristina disgustedly tells him to go clean himself up. Then it's her turn; she confesses that she's pregnant. "I win." Yes, I believe she does. Suddenly, there's a crash and a thud behind them. They turn to find that Joe the Bartender has collapsed. Cristina: "Okay, maybe Joe wins." Credits.
