Riley (while searching the victim's apartment): Naughty drawer.
Riley (picks up a bag of weed that's in the drawer and sniffs it): Hydroponic, medical grade, put-you-on-your-ass, send-you-to-dreamy-land weed. Nurses always got the good stuff. (smells the weed again)
Catherine: Ah, I take it you're aware of labs random drug testing policy?
Riley: Yeah, I got a bottle of clean urine in my locker just in case. ... I'm kidding.
Catherine (laughs akwardly): Ah, good one. I'll bag it. (Catherine smells it before she bags it)
