Our gang of interns enters the testing room. Shockingly, there about twenty people already in the room. Do you think these other interns ever get sick of the constant drama surrounding the fearsome five? I mean, do you think they're ever in the locker room at the end of a long day just hoping and praying that Izzie or George or Meredith doesn't have some kind of freak-out? Or do you think they enjoy the show? Maybe take bets on which of the fearsome five is going to sleep with an attending next? Izzie sits down and seems put out that George doesn't sit near her. And then the test begins.

Addison is about to do an ultrasound on Joe and Walter's baby mama. Joe is freaking out just a bit, noting that he really wouldn't mind waiting outside if it would make the baby mama more comfortable. We finally learn from Addison that baby mama's name is Serena. Good enough for me. Serena says that she's fine with them being in the room, unless it makes them uncomfortable. Joe starts to tell us that it really does, but Walter pats him on the back and says that he'll be fine. As Addison smears on the belly goop, Serena tells Joe and Walter, "This baby deserves parents who are gonna make it their whole world, you know?" Joe asks her if she's aware that they're gay. Serena: "I figured, with you both being boys and everything." She tells them that she's considering another couple who are about 40, where the woman has been trying and trying to get pregnant for ten years. Well, if she's the only one trying, I think I've spotted the problem. Addison, who can't help but take all of this in, interrupts to show them the heartbeat. Joe and Walter are both pretty excited to check it out. Serena, with a fine grasp of the obvious, tells them, "It's like a person inside of me." Addison: "Actually, there are two people. Twins." And then Joe faints.

In the test room, the proctor is announcing that they're halfway through the allotted time. And then we get an extended series of shots of people taking the exam. Scintillating. And then George looks over at Meredith and sees that she's just sitting there, staring into space. She hasn't filled in a single bubble. Commercials.
