I'm going to sound stupid for asking this but (contains major spoiler..)
At the end of the film, when she thinks Denzel is going to give her the money, he shows her the briefcase or something....why does she then try to kill him?
Surely she wouldn't be worried about him shopping her to the police as he couldn't do that without landing himself in trouble? So why doesn't she just take the money (she doesn't know there is no money in the case) as dissappear?
I can't understand the point in trying to shoot her so called child hood sweetheart? (Yes I know she obviously doen't love him cos she's conned him but to just shoot him seems a little....I don't know...pointless?)
