Lexie walks in to Justine's room just to see the woman wince from a particularly bad headache. She points out that clipping the aneurysm would take care of those pesky pains and adds that she's sure that Justine's publisher would extend her deadline. Justine explains that she's not worried about the publisher, just about her readers who are waiting for her to finish a 10-year series of books. Lexie's less than tactful when she expresses surprise that Justine is that popular and earns a withering stare; she apologizes quickly and points out that surgical residents don't have a lot of time to read. To everything Lexie says Justine insists that she needs to give the readers closure on Kate, Nathan and Alexander, and that she doesn't want to risk that she might not come out of surgery and would then leave everyone hanging. When Lexie tells her simply that she just wants to help, Justine raises and eyebrow and asks how fast she can type.
Cristina is surrounded by books with post-its marking hundreds of pages when Richard walks in to see Heart in a Box. "Hot diggity." He makes me think about one of my most cherished gifts, the Hot Diggity Dogger. I suppose if anything can hold a candle to a dedicated hot dog toaster, it's a heart in a box, so I'll allow his excited use of this expression. Cristina ignores him as she clearly doesn't share his appreciation for HIAB, and he finally asks what she's doing. Once she tells him, he snatches her list to read it before she can stop him. He flips through pages and pages and, disappointed, tells her that the list is full of totally common procedures. Cristina helplessly argues, "She let a starving person loose in a grocery store!" Richard offers her some advice, telling her that the heart is the key to the list. Cristina looks at him as if he's completely nuts, and has no idea what he is talking about when he tells her to unlock her mind. He won't help her any further than that, though, and just exclaims one last time of the Hot Diggity Hearter before leaving Cristina alone with her list that's the equivalent of a week's worth of Oreos and soda.
Mere has Mrs. O in a wheelchair and they seem to be waiting, so Mrs. O wants to hear all about how she's been. She's thrilled to hear that Mere is married and doesn't notice Mere's grimace when she asks if they have any kids; Mere tells her they are working on it. Callie and Arizona then round the corner and Callie is shocked and speechless to see her dead ex-husband's mother in front of her. She gives her a big hug and apologizes for not calling, then gets worried when she realizes that her former mother-in-law is a patient. Mere tells her that they are waiting for a CT, and that's when Mrs. O realizes that someone else is standing there. Callie takes a moment and then finally introduces her wife as merely "Dr. Robbins." A tech calls and Mere gleefully rolls Mrs. O away from the awkward conversation, and then Arizona gets a call from Polly and head off to meet her. As she goes, she pointedly tells "Dr. Torres" that she will see her later.
