Bailey (walks into her mouse lab to find Mer in there): Wha-- What the hell are you doing in here?
Meredith: One second.
Bailey: In a second I'm gonna kick you in your sorry--
Meredith: I just need to see if the cell survived. Yes, yes. The cell survived.
Bailey: What are you talking about?
Meredith: My mom was wrong. It's oxygen. The cells aren't gettng enough oxygen. She extraplated the amount delievered based on tests with mice, but the internal structure of an islet cell of a mouse is completely different than that of a human. Her hypothesis was wrong. That's why the cells in your device are dying. I marked the page for you. (runs out of the lab)
