Things are getting worse with Adele Webber at home. She starts a fire in the kitchen, causing Richard to burn his arm. As Meredith patches him up, she tells him to consider round-the-clock care. Adele doesn't take well to their visit to a nursing facility, but she takes even worse to the presence of an in-home nurse. Finally, in a moment of clarity, Adele remembers she has Alzheimer's and agrees to give the home a try.
Picking up from last week, Alex (along with Lexie and obviously Arizona) is trying to keep Morgan's one-pounder of a baby alive. Morgan's BF has arrived from Cleveland and is reluctant to get close to the baby, given the 15% survival chances. Morgan finally gives him an out -- leave now, no strings -- and he takes it, which clears the way for Noble Baby-Saving Alex to eventually move in as her boyfriend.
Derek finds himself getting the stink-eye from fellow parents when he brings Zola to daycare. He think it's racism from people who are weirded out by a white dad with a black baby, but with even Bailey looking at him weird, it's gotta be something more than that. Indeed, by episode's end, Derek blows up at a nurse, making a Big Statement about everybody needing to get over their bigotry, until Bailey pulls him off his soapbox and tells him they're not staring at a white dad with a black baby, but at a clueless dad who's allowed his black daughter's hair to look a mess. Bailey ends up giving a lesson in black hair-care and Derek learns a new thing about the universe.
Cristina and Owen are still having huge problems and Cristina begins to suspect that Owen's cheating on her with Nurse Summer Glau. There's nothing completely incriminating, and she ends up snooping through his stuff trying to find something. She comes up empty, but A) the fact that she has to snoop is a bad sign, and B) the show isn't all that interested in ruling the idea out.
Meanwhile, Teddy is still being awful to Owen, refusing his help with a grant proposal and snapping at him in front of an OR full of doctors. On the latter subject, Callie tells him he can't just take that kind of attitude, as the chief. And Avery is feeling overly stressed about the Boards, so Sloan is his disgusting self and tries to pimp out Kepner to him. Gross old toad.
Cristina is stalking around the halls of Seattle Grace like a zombie, following one particular nurse, played by geek-boy dreamgirl Summer Glau. Meredith runs up to her all buzzing with the knowledge she's been gleaning from Callie's Super-Method tutoring sessions. Cristina pays her the minimum attention possible while keeping her eyes trained on Summer.
Elsewhere, a waaaaay too happy Lexie runs up to Alex and informs him she's on Peds duty today. She must still be buzzing from having saved Rayanne Graff's life last week on Private Practice. She's also jazzed to be off of Derek's rotation, since working the brain-surgery beat has her dealing with a lot of dead patients. Alex is all, "Yeah, well, not so fast," as they'll be dealing with the preemie ward today, meaning babies with low birth weights and slim chances for survival. Like the 14 oz. baby that Intern Morgan gave birth to last week. She's wheeled in by her boyfriend, who looks cute and disheveled and, of the two of them, decidedly pessimistic about their baby's chances for survival. Lexie introduces herself to the boyfriend, Chris, and makes note that they haven't picked out a name for the kid yet. Chris says they should maybe wait until they're out of the woods. The kid's weight is up to 14.3 ounces today, but as Chris plugs those numbers into some program that predicts the chances of preemie survival, it's still only at a 13% survival rate. Arizona shows up and says the weight gain means they're "headed in right direction" BUT there's also a problem with the baby's bowels, so they're going to have to operate. It's a surgery with a 50% mortality rate, Chris frets, but as Alex reminds them, this one's a no-brainer. They don't operate and the kid dies. So it is.
Derek arrives at the Seattle Grace daycare facility and runs into Dr. Bailey. They do some small talk about surgeries, but Bailey finds herself distracted by the sight of little Zola in Derek's arms. The plinky/goofy Grey's comedy music means this isn't something dire, but something is definitely amiss. After Bailey makes a hasty retreat, another woman, blonde and fake-tanned, passes by Derek and Zola and shoots him A Look. Derek is troubled.
Dr. Altman is making a presentation to the Seattle Grace Hospital Board (because I guess Mitch Pileggi had a day off and could use a paycheck). She's got this proposal for a project where she uses stem cells to grow a heart. Too bad she doesn't have her shit together and can't find the right slides on her presentation. Oh, Teddy. Girl, call up Jennifer Garner and Keri Russell and have them tell you it shouldn't be taking you this long to get over Scott Foley, okay? Finally, Pileggi gets impatient and is like, "We have your proposal in writing, we will look it over." Altman reminds them that the procedure could save tens of thousands of lives, and to consider it carefully, but from the "bitch crazy" eyes Pileggi is shooting at her, she knows she kinda blew it.
