She's reading it at lunch when Alex and Cristina plop down at the table and gripe about the Mercy Westers. The story about the maniac with the hammer has spread, and Cristina indignantly defends that Avery didn't save anyone, he just did a "ninja leap" and tripped the guy. She reminds them that she used actual medicine to save someone. Lexie then tells them that she stole the notebook, and Cristina looks like she suddenly has a whole new level of respect for the Lexipedia. It's too much for her, though, and she puts it away and vows not to sink to their level. She complains about how they are vindictive and aggressive, and how that spirit could infect all of them so they have to fight it -- to which Cristina and Alex remind her that she stole the notebook. Out of real arguments, she says April's really not a nice person. Izzie then comes up with two coffees, and Alex assumes one is for him -- when they find out that it's actually for Charles, everyone gets mad at her. Izzie just acts high and mighty like she does so well, and tells them to get over their egos, and that they can't write off all of the Mercy Westers just because they feel threatened. Cristina and Alex bluster that they aren't threatened, but Lexie concedes that actually they are. Alex then looks around and realizes the only people there are in blue scrubs, because the invaders are all working. Panicked, they all get up and run back to work.
Cristina runs in to find Hunt and Avery working on some mass that has formed on Frank's leg that is most likely a pseudoaneurism. He tells Avery that if that's what it is, he gets to scrub in to the surgery. Avery gives Cristina a sly look and thanks Hunt, which is the last straw. She pulls Hunt aside and he tells her simply that Avery was there and she wasn't. He turns to walk away, but Cristina screams his name, silencing everyone for a second. She shakes off his confused touch of her shoulder, and yells at him for prioritizing based on some random code. I don't think it's random -- I think it's a) who is there and also b) he might be overcompensating a bit to look like he's not playing favorites with his girlfriend. Maybe that's just me, though. He tells her that it's just one surgery but her will is broken and she slumps off, telling him to forget it.
