Party time! Except that it's a rather sad little party in the lounge, with only Mark, Lexie and Richard there to surprise the departing ladies. Arizona is delighted but Callie is disgusted and just asks ungratefully if this is a party. I get it, I do -- this is the saddest party around -- but the fact that she'd just blurt that out is a little bit disgusting. Lexie meekly says that it was a busy day, so Callie snidely responds that she understands, even though she's been there since residency, that people are busy. Richard manages to stay upbeat and teases her that since they are two attendings down so of course they are busy, but Callie just shoots back at him that she's glad he could take time out of all of his "big plans" to come join them. In real life, this would be burning bridges in a rather spectacular fire, but here everyone seems to just take it. Admittedly, Richard is also being petty but as her former boss, it's kind of interesting that he just lets her be such a snot to his face. After he leaves Arizona tries to smooth things over by saying he's just crabby and trying to mess with Callie's head, but she doesn't mention anything at all about Callie's even worse crabbiness, and she bitches that she'll never know if that's what's up, will she? Everyone is uncomfortable while Callie takes a giant bite of her supermarket cupcake. Arizona seems to have had enough for now, and thanks the others sincerely for the party before leaving to pack. Once she's gone, Callie heaves a martyr's sigh and says she doesn't want to go home, so Mark offers, "You want to see us give a lady a really big ass?" Lexie gestures to prove just how big it's going to be, and Callie happily accepts.

Night has fallen, and it's still pouring rain. Do you ever wonder if the producers regret setting this show in Seattle, where they have to make it rain all the time? That's got to be quite a water bill, though I applaud them for their accuracy. If looks could kill, April would have killed Owen dead by now as she does compressions on her dummy and gripes about the imaginary helicopter that still hasn't arrived. She really seems to be cracking up a bit as she starts maniacally laughing about their situation, but when Owen snaps at Steve for him to bring a new card, April screams and throws herself on her dummy, not wanting it. She then proceeds to guess everything that the card is going to say about all of the bad things her dummy has developed, which impresses Owen. But this seems to have sent her completely over the edge, and she jumps up and grabs her dummy, getting Alex to help her throw it in the ambulance. And I'm not kidding -- she literally tosses it inside. Owen is trying to reiterate that the ambulance was part of the accident and can't be used, but April just jumps in the cab and starts it, screeching gleefully that she's got AAA. She finally turns on Owen and, like she's possessed, yells at him to get out of the way or she'll run him down. She then takes off, and Alex and Owen run inside to meet her at the other doors.
