Lexie's so relieved to get away from Mark that she doesn't notice that Meredith has her Professional Serious Face on, and she doesn't find anything remiss on the chart when Mere hands it to her and asks if she sees anything wrong. Mere finally points out Mitch's signature when he came in versus the one when he was discharged, which amounts to a squiggly line that droops down to the bottom of the page like it's trying to escape the paper and is making a drunken run for it. Lexie finally realizes what's wrong and Mere tells her about the stroke, then points out that she knows Lexie knows the symptoms, so was she distracted by all the Mark stuff? Lexie maintains that he had classic migraine symptoms and that he couldn't have been having the stroke when she was treating him, but that sad signature line tells another story. She's saved further lecturing, though, because Callie walks by and yells at Meredith for not telling her that her consult was for Adele, since she would have come down faster if she knew. Everything seems to be weighing heavily on Mere's shoulders, and she shuffles off after Callie to go see Adele.
Adele tells her story to Callie, who informs her that she actually has a hairline fracture, but that she'll splint her up and send her on her way. Richard then gets paged and takes off as well, leaving Mere and Adele alone, and Meredith thanks Adele for covering for her earlier. Adele has no idea what Mere is talking about, and Mere realizes she doesn't even remember that happening. Very casually, Mere asks her if she remembers hitting her head when she fell but Adele does not. When Tyler comes over with Oliver's scans, she quietly tells him to order a head CT for Adele. She then looks at the scans, swears, and runs off.
Teddy has changed for her date and is looking hot and Amazonian in tall black heels as she walks up to William and Henry, who have been visiting all this time. William is impressed to learn that Henry played professional baseball for a short while, and Teddy grins and grits her teeth as she admits she didn't know that about him. Henry starts to send them off on their date but Meredith runs up to show Teddy Oliver's scans, which have something on there bad enough for Teddy to again have to postpone dinner. She offers to reschedule but William assures her that she's saving lives, and the least he can do is take her to dinner when she's done. William reminds me of a hot Ed Helms so I kept expecting him to suddenly be wacky, but he's just extremely earnest and in awe of Teddy. He sits back down with Henry while Teddy tells Mere to get a CT. They hear giggling from somewhere as they walk down the hall; I thought at first that these were delighted squeals coming from the on-call room but they are actually coming from Lucy, who seems to be having a ball helping Alex with his charts.
