Ian Edgerton (from above): Or places where they had a second car waiting.
Nikki: You always got to make your appearance like that?
Ian Edgerton: People just don't seem to notice me until I talk.

Alan: Yeah. What a year! You get stabbed, Charlie gets shot at, both nearly lose your jobs. And if I was to inventory it, it gets train crashes, your escaped convicts, your serial killers, bank robbers...

Don: No, Gary Cooper, Mr. Deeds Goes to Town. (Alan laughs) Talmud's got some good stuff too.
(Nikki and Edgerton leave together)

Liz: No! I always thought he had his eyes on you. (points at Colby)
