Dr. Cassidy: This is the best chance he has!
Dr. Mike: No, I'm the best chance!
Dr. Cassidy: That's your opinion. But he's my patient and I'll decide what's best for him.
Dr. Mike: Dr. Cassidy, if my name was Michael Quinn and not Michaela, you'd let me perform that procedure wouldn't you?
Dr. Cassidy: I don't give a damn what your name is. I know Drew. And I know he would much rather take his chances on a wagon trip to Denver than have a hysterical female cut him open!
(later on, after Drew is brought back, having died on the route to Denver]
Dr. Mike: What do you think his chances are now, doctor?
