Cut to Mary's room, where Clay can't really wrap his head around what Derek is saying, since they've seen lots of surgeons and all have told them that surgery would likely put Mary into a coma or kill her. Derek tells them that he just wants to take a new scan, and Mary is all for it and manages to convince Clay to at least let her do that though he's not happy about it. Seriously, isn't it amazing that they have seen so many surgeons but happened to skip over the world-renowned brain surgeon that happens to work where they live?
April, stressed (as usual), stretched too thin, and desperate for help, grabs Meredith to assist her with mouse research. Cristina is hanging out in April's office, doing research on Tyler's surgery and feeding a piece of confiscated doughnut to a Mouse Q who doesn't know that he's diabetic and it might kill him. April does, though, and in her harried state she can only shriek and grab his cage away from Cristina. When it comes out that April wants Meredith to run some tests on Q, Cristina thinks April is just giving her grunt work while Mere points out that grunt work or no, Bailey hates her and holds her responsible for Richard losing this trial so would never, ever let her participate. April answers that this is why she'll be doing it in secret, and Cristina says what we are all thinking: this is the worst idea she has ever heard. When Meredith agrees, April realizes that she's again facing residents who just blow off any of her orders and so she takes what Alex said to heart and switches up her approach. She puts on a strange, deeper, kind of growly voice that sounds like it might hurt her throat after a little while, honestly. She threatens that if Meredith doesn't do this, she'll make her life hell, putting her on call every night and assigning her only the most disgusting patients. Meredith doesn't get scared but she does agree to do it, maybe just so April stops her "mean" voice, and Cristina actually seems a little bit impressed. When April asks if Meredith really agreed just because she changed her voice, Cristina warns her to leave before she can embarrass herself more, and April does. Cristina's phone then goes off and she leaves to go answer her call of duty. Mere asks suspiciously if they have talked yet but they seem to have just replaced talking completely with sex. Cristina still isn't interested in talking and points out that Meredith has her own issues, spending her fifth year delivering babies and playing with mice. Meredith has no comeback for this, and Cristina skips off to her husband.
