Cristina and Feeny talk as they work, and he says that if this surgery goes well he'll put her name first when they publish. They joke a bit but Cristina keeps reminding him that this could very well be his last surgery ever. He says that he's relieved he never had kids since they would have turned out just like her, and Cristina shoots back that she knows she's his dream come true. Suddenly serious, he agrees; she lets that sink in a moment before cracking another joke to escape the sudden sincerity.
While that's all very civilized, Mere's frantic surgery takes a turn for the worse and she realizes that someone moved their hand. After Mere yells at them, Heather admits in a tiny voice that she moved just a little, but she's shocked when Mere admits gruffly that it's okay and that it actually will help them locate the bleeder. With that, they all seem to realize she's not actually Medusa after all (even though she never acted that crazy after the first episode anyway). She then orders them to hold still totally for reals this time.
Feeny is feeling his oats, giving Cristina all sorts of advice while they work. He tells her not to be crass, even though her whole generation thinks they need to be crass so that everyone will realize how tough they are. He advises her that other women already fought the fight so she could be there doing this work, so she should find something else to fight for instead. He also catches her holding her breath and warns her that when she stops breathing, she stops thinking, so she needs to remember to breathe.
While he calmly teaches Cristina, Mere yells at her interns to stop looking at the monitors and to just help her find the bleed. As Melissa continues to deteriorate, Mere digs through Melissa's organs and keeps mentally chanting to herself, "Don't panic!"
