(Izzie tries to enter the bathroom but the door is locked) 

Izzie: George. You locked the door. I need to take a shower. 

George: Uh, uh,  I'll be out in a minute. 

Izzie:  What are you doing in there? 

George:  It's private. 

Izzie: Oh. Oh, God. I'm sorry. I get it. I didn't mean to interrupt. 

George: No, it's not that! 

Izzie: It's ok. Take your time. 

George:  I am not doing what you think I'm doing. 

Izzie: You know what, there's really no need to explain. I'll wait. You just...finish. 

George: No, I'm...I'm coming. I'm coming out.
