Once they've gone, Sunshine Erica comes out of the room and they comment on the awesomeness of the apartment. Erica touches Callie's back familiarly but Callie flinches. Mere's disembodied voice finishes: "We usually know what we're doing and when we don't, we still act like we do. We walk boldly into undiscovered country, plant a flag, and start ordering people around. It's invigorating, and terrifying." Hahn asks Callie out on a real date, as she explains, one with dinner, wine, and her trying to take Callie's clothes off at the end of the night. Callie is clearly nervous and comments, "That would be a date!" Hahn, though, just grins back at her. I refuse to believe that she would really be so oblivious to Callie's nerves or that she would just ignore them. It's a weird writing choice for these two.
Mere gets home to find a still-naked Derek reading in bed. She notices he's got a diary on the bedside table, and flirts up a storm about how cute it is that he keeps a journal, as she climbs on the bed. He corrects that it isn't his, but when he tries to kiss her, she pulls back and suspiciously asks whose it is. He fesses up that it is Ellis' journal, and that he found it in a box of medical journals. Meredith of course goes all damaged and silent, and Derek tells her he didn't read it, but that he brought it for her. She just demands to know why he was going through her mother's things, and he explains that he was trying to find a place for his clothes, as her closet is full. Rather than try to talk about it, she then excuses herself to take a shower and grabs the journal on the way out while he pouts in bed. If he's surprised at this, then he doesn't know her as well as he and everyone else thought he did, as this is Meredith 101 right here. It doesn't mean it's not annoying, but it certainly isn't a surprise.
Our four residents approach a nurse's station followed by their pack of mostly unidentifiable interns. Mere is bitching about the journal and her boyfriend, but when Cristina asks she says she hasn't read and won't read any of it. She then wants to know why her boyfriend is snooping around the house anyway. Cristina is able to be herself with her best friend for one second and answer, "I think because you invited him." The Chief starts yelling because everyone has still managed to try and stay on their would-be specialties. He reminds them that it isn't allowed, and says that Bailey will be giving assignments and they aren't allowed to argue. He stomps off and O'Malley runs after him, but before he can ask, Richard tells him that he doesn't have George's test scores and will let him know as soon as he has them. Lexie overhears and rah-rahs that she's sure he passed, and she'll buy him a beer at Joe's that night to celebrate. George asks what will happen if he doesn't pass, and she promises to still buy him a beer. "Beer for losers."
