Teddy: Dr. Yang can you tell me why you entered the plura with a Kelly clamp?
Cristina: Why? Am I too low? Do you suspect a traumatic herniation?
Teddy: No, no. I just wanna know your thinking.
Cristina: Because that's how you put a chest tube in.
Cristina: What do you mean why? Because you'll kill the person if you do it wrong.
Teddy: Tell me like I'm an idiot, like I'm a medicial student.
Teddy: I need to make sure your foundation is solid.
Teddy: I'm asking the questions, Cristina. Not you. Tell me why you entered the plura that way.
