When Reese and Finch go to intercept the consulate car transporting Heinlein, Reese parks his car sideways in the middle of the street. The view down the street shows a streetlight and several parked cars on the right. When Reese braces the sniper rifle on the car and looks down the street, the next shot places him approximately half the distance away from the same streetlight and parked cars.
Finch: No thanks, I don't drink coffee.
Reese: Sencha green tea, one sugar.
Finch: You've been paying attention.
Reese: Relax, Finch, it's just tea. I haven't guessed your favorite color yet.
Pilcher: Before the country reunified, East Germany was the greatest surveillance state the world has seen. The Stasi knew everything.
Finch: I've read about them. I'm a sucker for surveillance.
Pilcher: Um... how did you know about the submarine schematics?
Finch: Told you... I'm a sucker for surveillance.
Finch: Mr. Reese, I'm highly uncomfortable being here.
Reese: I'm highly uncomfortable having you here, but I need a spotter.
Finch: What if you miss?
Reese: I wouldn't know. Never have.
Reese: That's a Welrod, isn't it? Only 73 decibels when fired. But it won't stop me before I get to you. and I lose my patience when I get shot.
Reese: I always thought I'd die in a place that didn't know my name.
Finch: You think anyone will care for our names?
Reese: After we're dead.
Finch: I thought we already were.
