This scene happens virtually a couple of weeks before the agent woman actually kills this guy.
In fact she's not the one who will shoot. It's just a dream, that would have been too pretty. Also she's not a killer. She's an agent. She only planed his assassination.

In the way of her mission she teached this bad guy something he never lived before, or lived too far away. When he started to think she was a dangereous ennemy, he has already accepted his defeat. He wont do anything to stop her and let her bring his own death.
It is during this dream that he faces all his thoughts and when he decides to accept his fate.
The end was nicer in the dream than in real, for sure.

Secret Agent Challenge.
