Captain Montgomery: Mr. Castle's offered to assist with the investigation. Kate: Really? Castle: It's the least I can do for the city I love. Captain Montgomery: Considering the nature of the crime scenes, I think it's a good idea. Kate: Sir, can I talk to you for a minute in private? Captain Montgomery: Nope.

The Captain calls Kate over to the door of his office where he's standing with Castle. After answering Kate's question he turns back into his office.
