He runs back to the exam room and arrives at the same time Arizona to see Callie and Lucy in a standoff -- Lucy is sure the baby is okay but Callie still isn't convinced. It turns out Lucy was the one who paged them because Callie hadn't yet left the exam room two hours after the appointment. Callie just starts throwing out various possible complications and doesn't want to take any chances. Lucy is understandably frustrated, even though she's trying to stay nice, and finally Mark jumps in as referee and suggests that since she's there, why don't they just do a culture? Lucy agrees, but seems to be silently judging them to be a pack of lunatics.
Rose watches Daniel and Victoria cuddle and fiddles with her wedding ring as she tells Alex all about how they met in college 40 years before. After watching her husband and his faux-wife for a while she turns to Alex, tears in her eyes, and pleads with him to give Daniel the drug. Alex insists that it's totally random and not up to them but she insists that they could change it if they wanted to. She cries that she can live with sharing her husband with Victoria, but she can't live with losing him all the way. It's completely heartbreaking, and Alex is visibly shaken by the exchange.
He goes to Meredith to unload but she's not as sympathetic as he'd hoped, reminding him that he was the one who wanted in on this trial. He's already yearning for pediatrics where things are more straightforward with a sick kid and worried parents. Here, he points out, the patients don't always even know they are sick. Meredith finally relents a little bit and tells him a story about how she was visiting her mom one time when Ellis started talking about how she might have herpes. That's got to be in the Top 5 Conversations You Never Want To Have With Mom, with the likes of "It's been over four hours and I think something might be wrong with your father," and "Well, I'm not totally sure since I was 'friends' with a lot of young men when I found out I was having you." Meredith realized that her mom thought that Meredith was her best friend from med school and that it was 30 years earlier, and she sat there for two long hours and talked with her about her possible herpes. As she explains to Alex, while she couldn't cure her Alzheimer's she could give her mother what she needed at that moment.
Cristina goes to Martha's room and finds her looking at pictures of her family, her doubts about the surgery growing. As she looks at the pictures she tells Cristina that a friend had surgery and wound up in a nursing home, which was hard on her kids, and she gets more and more agitated and cries that she can't become a burden to her children. Cristina hears her out but reminds her that without surgery, she will have a few months, and her family will always be afraid that she's about to go. With the surgery, she could go to her grandchild's wedding. Sincerely, she says, "Don't give up on yourself. Let us help you." Despite all of her jockeying for position all day, this comes off as totally genuine, as Cristina herself almost gave up and had others that helped her. Martha thinks about it, and after Cristina promises that she will be there, Martha agrees to do it, scared but sure. Cristina turns and sees Jackson watching, and when she walks out of the room he bitches that she can't win the surgery just because the patient requests her. Cristina just tells him that not everything she does is because of competition. He doesn't believe her but in this case, I do. But let's be clear that I also believe she's not above using that to her advantage as well.
Mark is walking across the bridge when his pager beeps yet again, and as dramatic drums start to pound he turns and sprints down the hall. But as opposed to being the emergency it seemed, when he gets to Callie he reads her the riot act for paging him 911 when nothing was actually wrong. Lucy just keeps her head down and does paperwork while Callie sobs that something could be wrong, and that she's a "hormone casserole" and can't handle being yelled at. She cries that she has a gut feeling something is wrong and at this, Lucy discreetly hands over a box of Kleenex, possibly starting to sympathize a little. Callie cries that she's not sure she believes that Arizona is really in this with her but by this point, even Mark knows she's being crazy and he tells her that he believes Arizona isn't going anywhere. This line of fretting mercifully shut down, Callie changes direction and asks him what he's going to do about Lexie, and in doing so works herself up again, yelling that everything in her life is a disaster. She doesn't want the baby to be one too, and she's terrified that she's going to screw something up. Mark realizes they've finally gotten to the actual heart of the matter and he gives her a hug while Lucy looks on.
Cristina is updating Teddy on Martha when Jackson runs up, and Teddy steels herself for more bickering. They want to know who's going to assist but Teddy points out that their patient care is the best it's ever been, and if she tells them now one of them will just run off and sulk. Jackson, who is just doesn't play in the same league as Cristina, is just about ready to do that anyway; he's obviously wiped out by keeping up this competition and brats that he's the obvious choice since he's been practicing this procedure in the lab for a month. Cristina just counters that she doesn't need practice, and Jackson is left having to admit that yes, she has more experience. But then, as he's fatigued and there's only a few seconds left in the game, he makes a clumsy rookie mistake and earns himself a technical foul by shooting back that Cristina hasn't exactly logged a lot of hours in the OR these past couple of months, has she? Cristina thinks a moment, and then just turns and marches away. Teddy asks if he is really so insecure that he had to go there, and Jackson slumps and says he's not insecure, he's an idiot. Oh, I think there's plenty of insecurity tossed in there too. He obviously regrets it the second it's out of his mouth but still, there you have it -- he just as obviously totally lost the game for himself on his own dumb mistake.
Jackson finds Meredith and rushes her to the locker room, where it seems that Cristina has once again unraveled. Cristina, head in her hands, cries that she wants Owen, and Meredith sends Jackson to find him. Once he's gone, though, Cristina jumps up triumphantly and begins to eat an apple with as much sass as she's ever had, pointing out that Owen's at the dentist, which is going to make him hard to find. Meredith is genuinely appalled but at the same time can't help but break into a grin to find Cristina doing so well that she's back to her underhanded tricks.
Either because she was moved by Callie's tears or because she desperately wanted her exam room freed up, Lucy wheels in the mother of all machines with the highest resolution possible. She warns that even with this it's still hard to find the heartbeat, and pointedly adds that she doesn't have most mothers come in until after the eighth week because when they don't hear a heartbeat, they freak out. Callie has calmed down enough that she totally picks up on the emphasis there and looks the tiniest bit sheepish. But since she's there, Lucy says it can't hurt to have one more look.
Richard, Lexie and the others are just hanging out in the OR, waiting for Bailey, which gives the perfect opportunity to expose Richard further to the world of Twitter. Lexie asks a question that someone sent but then puts on her Bambi eyes and says that they aren't tweeting, so she'll ignore it. Of course Richard goes ahead and gives her the answer, and then another. Then a former resident sends a hello message, and Richard is totally charmed to hear it. He seems to be coming around that there might be something to this tweeter nonsense after all.
Soulful surgery montage! Alex and Derek prep Daniel for surgery while Teddy and Cristina work away on Martha. Jackson finally runs in, late and ticked off after his fruitless search for Owen, and he realizes he was played. Richard is now totally caught up in the fun of answering questions over Twitter and is giving Lexie information faster than she can even type. Bailey then runs in with a cooler containing the cells they need, and they all get back to work while Lexie keeps the world updated on their progress.
Up in Callie's room, just as she's sure that they aren't going to see anything because it's too early, Lucy picks up on something and they hear the gurgly thump of a heartbeat. Everyone grins and Callie's eyes fill with tears, but happy ones this time.
