When Lexie returns from her cupcake run, Mark is dismayed to find out that she just got some from the grocery store, when he thinks that Callie and Arizona deserve top-notch bakery concoctions. Lexie doesn't really care, though, on account of the fact that she's a doctor rather than an errand girl, and because she's worried that Christy is making a mistake. Mark says that it's not for Lexie to say but Lexie persists that someone has to, because the only reason a woman does something like this is to impress a man. She goes on that this is just the first step, but then she gives up her friends, moves in with him before she's ready, and then if she's not careful winds up a 26-year-old stepmom to a pregnant daughter she never knew he had. Then after that she finds herself single and dying her hair, but that becomes a problem because one can't keep up with their roots when they are committed to the psych ward. Now hang on a second, this is another storyline that I feel has relied on some revisionist history. I don't recall Lexie giving up her friends, she could have said no to moving in and to be fair, he didn't know he had a daughter either, much less a pregnant one. This isn't to say that Mark wasn't at fault with a lot of how he handled those situations and their relationship, but the decision to pin it entirely on him just rings false. Also? Lexie, you were in the psych ward for only a few days. Your roots were probably fine. And also, everyone else has already LET IT GO so please do the same!! Mark seems to have that same last thought, he asks, "Psych ward?" and she just claims, "It happens!" before heading off.
Derek is staring at his generic-logoed laptop when Bailey walks in, but she heaves a sigh when she sees him and asks where she should go to sulk since he's already claimed the room. He invites her to join him since he apparently was already having a pity party for one, and asks her what's up. She complains about how she's desperate to figure out what happened to Mary and how she could have survived the shooting only to die from routine surgery, but that Dr. Anna is only worried about her dinner reservations and her lunch. Has she magically forgotten that every other surgeon in this hospital spends all of their time in surgery discussing nothing but personal matters, most usually too personal to be appropriate? Though to be fair, she herself actually is the one who mostly manages to stay away from that kind of thing. Derek stares at her and finally asks if she's feeling better, but getting it off her chest hasn't helped. Instead she asks him what he's doing, and he explains that the more research he does about Alzheimer's for his proposal, the more depressing it gets, especially when one then tries to add in the information about the early-onset variety like Ellis had. Bailey doesn't have a good response to this, because it IS depressing, and instead gripes that Anna chews gum while she works. Derek can't help himself and laughs, admitting that it's disgusting. She manages to laugh too, and then thanks him.
