Mark: Is it true you punched a guy?
Owen: Shep, I need a neuro consult.
Derek: Why because you punched a guy?
Richard (walks up): What's this I hear about you punching a guy?
Owen: Alright, yes. I punched a patient who was endangering the safety of my nurses, my residents and my other patients.
Mark: You know, you're the chief and not the sheriff, right?
Derek: Scan is clear.
Owen: Thank you, all of you, really.
