Gotham, Season 1

Carmine Falcone:
That was your father's. He gave it to me a long time ago. A spur-of-the-moment birthday gift. I said no. Such a beautiful knife, and I have men with guns to protect me. He said take it. A knife is a good friend when you have no other.

Jim Gordon:
You were that close.

Carmine Falcone:
At one time. The point of the story, Jim--your father was the most honest men I ever met. But he carried a knife.
