The reunion we've all been waiting for takes place outside the elevator when Addie gets off and runs into Alex. They greet each other awkwardly and then she hugs him, which he returns with one confused arm while pointing out that they're hugging. She cheerfully tells him, "I hug now!" Come to Los Angeles, folks -- we're so ready to hug we'll greet strangers off the plane! It seems he's "her guy" on the surgery and he cracks that he wouldn't let anyone else have a case like this... when who should appear behind her but Ava. This is starting to get a little bit old. He asks if she owns a phone but she doesn't take any notice of the tone and just tells him she needed to speak to him in person. He tells her he's busy so she announces, "I'm pregnant." She then claims to his surprised face that he never has time to talk so she had no real choice but to blurt it out. Just get him in the on-call room -- he's always got time for that and then you can blurt it out not in front of all of the staff. He just asks, "Are you keeping it? Or are you having an abortion?" Ava actually deviates from her normal blank stare to pull back in shock but Alex just reminds her that he's got a big case, and he takes off.
The pertinent staff members, which in this case are most of our regulars, are in a meeting about the big case -- their patient is a baby in utero whose heart is growing outside his body. Very few cases have ever been recorded and even fewer survived, so it's a pretty Big Deal. Addison tells them that she had a case like this ten years earlier where the baby squeezed his own heart in utero and died. They go over some possible complications and Hahn tells her they've got a lot of work ahead, but they have a rah-rah moment when Addie asks if she's up for it and she replies, "Always." Mark tries to get in on that action by reminding them about the skin-growing, but it only makes Alex look at him like he's a doofus. A really hot doofus, but a doofus nonetheless.
George comes into the clinic and as he passes Izzie's interns, the air is thick with inside jokes. Izzie had paged him so that she could make him feel guilty for having a party without inviting her -- she apparently spent her evening googling recipes. (As someone who has gotten caught up for hours reading up on random subjects on Wikipedia, I can't throw stones here. I also don't think it sounds like such a terrible evening.) George points out that he didn't think Izzie would want to spend an evening hanging out with the interns and seems torn between feeling like he has to explain himself and feeling cool and confident with a new group of friends. A new group with a horrible inside joke that involves telling someone they "coded," complete with hand signals. But while I hate most of these interns and the joke is annoying, it's nice to see George not acting like a kicked puppy, and it's also nice to see something annoy Izzie so badly. Lexie bounds up to tell George they're all set for that night, and at Izzie's questioning they admit the interns are having a darts tournament at Joe's. Izzie totally tries to push her way into the plans, so George asks meekly if she'd like to come. She happily agrees and as they walk away, Lexie informs him, "You SO coded."
