Castle, Season 5

Gates:
Your resignation has been accepted. The matter's settled.

Beckett:
Sir, I have the top case-closure rate in the precinct. And now that the man that shot me is dead, that particular case will no longer be an issue.

Gates:
Really? Because it seems to be the gift that keeps on giving. I'm told we put a Michael Smith under guard at the hospital. What was his role in this?

Beckett:
I don't know.

Gates:
I don't believe you. You're covering for someone and I know who it is. But I don't intend to dig up the past and tarnish Roy Montgomery's reputation. The fact is, I admire your loyalty. I hope you feel that for me someday.
