A Gun in a Little Handbag

Season 2, Episode 1: "Overkill"
"See, another nice thing about this bag is how much it pisses Flynn off."
Flynn and Provenza are the best of friends, but they just love to drive each other insane. When Flynn scoffs at the idea of keeping a gun in a decorative whisky bag, Provenza is instantly drawn to it. Provenza can't help joking around with a mafia informant about his new gun case, but the joke's over when the informant pulls the gun and puts it to Provenza's head, and Flynn's ready to do whatever it takes to save his partner.
