Will Jeffries seeks vengeance for his wife's death

[Jeffries confronts Keller in an alley. It's dark and raining.]
Keller: Whoa. Scared the crap out of me, buddy. Just closing up. You need something?
Jeffries: Winter of '95 was really something.
Keller: Yeah, it was.
Jeffries: Can't get it out of my mind.
Keller: Yeah, right. Well, you know. I... I should finish closing.
Jeffries: My wife was killed that night. Hit-and-run trucker. But you know that, don't you?
Keller: No.
Jeffries: She didn't die right away.
Keller: Oh, please.
Jeffries: Took a while.
Keller: Please. I... I... What? What? What do you... Want? Money? A-anything.
Jeffries: What do you think you can possibly give me?
Keller: I... I don't know. I...
Jeffries: You left her there to die.
Keller: Please. It was an accident.
Jeffries: You drove away. Close your eyes.
Keller: No. Please. Don't do this. Please.
Jeffries: I said, close your eyes.

And later, the boss makes a visit to Will's apartment:

Jeffries: Hey, John. Come on in.
Stillman: You haven't picked up your phone all day.
Jeffries: All this time... he wasn't what I imagined.
Stillman: What did you do, Will?
Jeffries: I followed him into the alley. It was dark, raining.
Stillman: Go on.
Jeffries: I put my gun to his chest. But I couldn't do it. I wanted him to be a monster. But he wasn't. He was just a guy in a diner. I thought... if I could do it... it would make it better. It won't.
Stillman: You did the right thing.
Jeffries: That night at Dink's, they were playing Miles Davis, her favorite. I... haven't played one of his records since. It's been 12 years.
Stillman: A long time, Will.
Jeffries: Yeah, it feels like yesterday. She's not coming back, is she, John?
Stillman: No, she's not.
