Meredith goes over to Tyler to review the status of all of their patients and then asks to see the charts of everyone who was recently discharged. The first one she looks at belongs to Mitch, Lexie's migraine patient with the awful girlfriend, and Meredith freaks out over what she sees and runs out to the parking lot to see if she can still catch him.
He's not moving terribly fast and so she gets to him before he's gotten into his car. Immediately she asks him to smile, and after a moment of struggling he's only able to lift one side of his mouth. She then asks him to lift his arms, but he can only lift one. Gia's more ticked off than worried at all this commotion but when Tyler runs out, Meredith tells him they have a code somethingbad and orders him to get a stretcher. She asks Mitch to repeat a simple sentence and he can't really form the words, which causes Gia to finally start worrying about something other than her ruined evening. Mere orders the woman to help her lower Mitch to the ground and as she shoots orders to Gia she informs her that Mitch is currently having a stroke.
Once they have him inside, Mere tells some random doc that his symptoms started 20 minutes ago so they are well within the "golden hour." Gia, meanwhile, is on the phone and is more upset that Mitch could have been driving her when this happened than she is about him having a stroke in the first place. Amazingly, though, this isn't her most self-centered thought of the hour. She outdoes herself when Meredith comes over and explains that since they caught this early they think he'll be eligible for a particular stroke medicine that should fix him up. Gia asks her how he's doing on a scale of 1-10, but defines 10 as needing to cancel their upcoming Aspen trip. Mere replies, very slowly as if Gia's mental capacity is, well, a little bit smaller than the rest of ours, that she should cancel the trip. Gia then gets back on the phone and begins to tell her friend what's up, all put out. While I'm sure a girl this idiotic would have idiotic friends, I'm still shocked that whoever is on the other end of the phone hasn't told her to get a grip yet.
Mark's taking his turn examining Stewart; his theory is that the knife itself is preventing any bleeding and they are going to have to crack open Stewie's head to get it out, but Jackson comments that they could try just pulling it right out. Dave's ears perk up at this but Mark berates him for what he thinks is a stupid idea and guesses that Avery just wants to get off work to go to the game. Lexie speaks up and defends him, though, pointing out all of the reasons why taking out the knife might just work and would be less invasive than doing a full-on craniotomy. Mark knows that's not why Avery made the suggestion but they move forward pretending that it was. Avery is honest enough to add that he does also want to make it to the game on time, though. Mere then pokes her head in and in her best no-nonsense voice tells Lexie they need to talk.
