The next morning, the split screen shows both of them sleeping in their chairs; Mere's interns are all staring at her, terrified to wake her up. Finally, Princess K pokes Mere at the same moment that Feeny yells at Cristina and they both wake up with a jolt, silently pleading for their patients to still be alive.
Not only is Katy alive but she's speaking and moving her extremities, so they are going to do her second surgery that day. Feeny takes a chance to tease Cristina, who is still trying to process the news through her sleepy haze.
Back in Seattle, Meredith explains to Kate, Smash and that girl Alex was sleeping with who I hear was on Veronica Mars that they need to go back in and do more surgery but right now Melissa is too weak to survive it. Basically, they are waiting for the one perfect moment to jump in and fix her up. I guess that these interns really are here to stay a while so I can make myself remember the last girl by the name IMDB tells me she has, which is Heather. They all hear a knock at the door to the ICU and look up to see Callie, holding Zola and waving frantically.
She's completely apologetic as she explains that Zola has a fever that's probably just from teething, but the daycare won't take her until she's fever-free for 24 hours and Callie has a surgery in ten minutes. As she says this she hands Zola over and then runs off to work. Melissa's blood pressure has chosen this totally inopportune moment to plummet, so Mere looks around for help and sees NotCristina again. Similarly, it looks like she's here to stay for a little while so I will actually call her Stephanie. (Also, after that first scene, she hasn't done enough to earn any other comparisons to Cristina.) I've learned your actual name, Stephanie -- don't waste it now. She protests that she already did a ton of personal errands for Mere the day before and she's there to actually practice medicine, so Mere tells her she can do so by monitoring Zola's fever.
