We left Lexie Grey last episode with her hand in a young man's neck (Seth Green) trying to keep him from bleeding to death. She can't move, but he manages to reach a phone and hand it to Lexie, who is able to call the nurses at the station. There is soon a wild commotion to help him, but Mark Sloan, his plastic surgeon, can't find an O.R. to operate on him. After all her hard work, they lose the patient.

Meanwhile, back in Alex Karev's surgery, he keeps looking up at Ava in the gallery. Mark Sloan notices and tells him "he's so busted." While distracted, there is a complication with the surgery and Alex is caught off guard. Erica Hahn is able to patch up the heart and the patient ends up okay, but Alex gets very upset at Ava for being there. He tells her he's been sleeping with Lexie, who she sat next to and told her she shouldn't have said he was her boyfriend, because he's not. He throws back in Ava's face that "at least [Lexie] isn't married with a baby" and tells her she shouldn't be there. Not exactly the nicest way to get through to a girl, but maybe she'll believe him and let go.
