In some fantastic multitasking, Arizona and Alex get the baby out while Derek starts on the mom's craniotomy, and Arizona tells Alex they need to get to the NICU right away.
We know they've made it to the NICU because everyone is in pink gowns instead of the usual yellow ones. A bit of time has passed and Alex tells them that the baby seems to be breathing OK, so they decide to extubate her. Arizona then gives Alex lots of instructions about what he needs to look for given that her head is still bleeding. It's 8:30, and she gripes about the rough start to her day but Alex snaps things right back into perspective by pointing out having a stroke before you're born is a rough way to start one's life. The baby is hooked up to all sorts of tubes, and wires are everywhere.
Callie brings Arizona some coffee and then Hunt greets them and immediately starts preparing for Cristina's arrival, since he knows she'll be mad he didn't call her and potentially mad at Callie for not waking her up anyway. Callie gives him a great, "Oh, don't pull me into this, buddy," look but he assures her he'll handle it, and warns them not to provoke her. Callie is incredibly skeptical that his plan is to ignore the "scalpel-hungry" animal but it's what he's going to do until he comes up with something better. Cristina then walks past them all with a slight smile, but other than that is pretty pointedly ignoring them, not giving them the chance to ignore her first.
As they all just happen to have child patients, most of the docs are all on rotation with Arizona that day. After getting in a slight dig at Cristina for her first try at peds (and Cristina at least looks appropriately abashed for a moment) Arizona tell them that she runs her department differently than other pediatric units. Avery is there, as well as Charles, who quite frankly I keep forgetting even exists -- I had forgotten he was in half the scenes he was in this week until I watched it a second time, in fact. Arizona then tells them all that this isn't general surgery in miniature, but that she treats her patients like tiny humans. Tiny humans who believe in magic and have fairy dust in their IV bags. (It sounds a little unsanitary to me.) Charles is skeptical, Cristina is disgusted, and Avery tries not to smirk but fails as Arizona happily tells them that kids hope and make wishes, which helps them heal faster and survive more things than adults do. Callie beams at her girlfriend, clearly proud, and Hunt looks happy at all the optimism too, though his girlfriend sticks her finger in her throat for one second to show what she thinks of it all before they go in for rounds.
