Down in the pit, a paramedic rushes in with a tiny newborn, who he tells Alex was found in a trash can. Alex discovers that the umbilical cord is still attached, and that the baby is dehydrated. He says he needs to start an IV. Nurse Olivia walks over and just stands there, staring. Alex yells at her to help him with an IV; Olivia says she just came down to help with all the flu patients. Alex looks around and sees all the sick people coughing in the baby's direction, and gathers him up. "If you think I'm leaving this sick, premature infant down here in the ER..." Olivia tells him he can't just take the baby -- he has to be admitted! Why is she being so weird? Alex keeps on walking with the baby. He calls over his shoulder, "Page Addison Shepherd. Tell her to meet me in the NICU." Fade to the little, little credits.

When we return, Alex and Addison are in the NICU with the baby. Alex reports that the baby has some sort of platelet problem. Addie asks where the mother is. Alex: "I don't know. The baby was found in a trash can at a high school." Along with this, the baby has intra-abdominal bleeding. Fun! Addison freezes for a minute, clearly thinking about something else, then gives Alex a bunch of orders. She finishes by telling him to find out where the mother is, so she can test for maternal platelet antibodies. Alex asks if she can't just do surgery to fix the abdominal bleeding. Addison: "If I wanted to KILL him, I could do that." Olivia walks in to tell her that there are some people there...about the baby. Ominous!

McDreamy and George are in surgery, getting ready to close up Gisele. McDreamy asks after Izzie. George says she's as well as can be expected. McDreamy imparts some wisdom to George: "It never gets easier, you know. Losing a patient." George says softly, "Izzie was in love with him. Denny wasn't just a patient. They were in love." Aw, George. Still romantic after three whole months.

Meredith's house. Cristina has had to sit down at the table to take in this news. "You had sex with Derek at the prom in an exam room?" Meredith says yes, but Cristina's not done. "Last night. You and Shepherd did it. You and McDreamy. Did the nasty, nasty." Heeee. Mere jerks her head up from the table. "Cristina!" Oh, what's the problem, Little Miss Dark 'n' Twisty? Cristina says she's not judging -- she's just trying to wrap her mind around it. She asks if Derek's leaving his wife, and we hear the ticking of the Flashback Clock.
