"You know I could just kick you out of my precinct, and even your contacts with the Mayor can't save you this time." Gates said as she addressed Castle who was staring at the ground guiltily instead of at her.

"And you," Gates continued, moving to stand right in front of Beckett. "You should know better. I should have you busted down to traffic, or suspended without pay. Again."

"Sir, if I can expl..."

"Do not interrupt me Detective. I do not care about what your excuse might be right now. I will only give this warning once, and only because your team happens to have the highest solve rate, but this sort of behaviour will not be tolerated again. Not in the evidence locker, the bathrooms, nor anywhere else in this precinct am I making myself clear?"

"Yes sir."

"Good. Dismissed."

As they left Gates' office, the guilty and serious look on Castle's face lasted all about one second. "Does that mean christening her desk is out of the question?"

Beckett's only response was to slap him over the head with a stack of files.
