I recently watched Wrecked, and there are some unclear parts. I realized that during the robbery, the men (robbers) dragged along the man only to use his vehicle. During that, we are shown the dumbfounded girl sitting on a bench after the quarrel (?) with the man. So I concluded that they are the fiancé and fiancée.
It also explains why the man sees the girl almost every time after the accident (she is constantly in his memory).
But the problem: why does he (try to) kill her? And also, whenever he sees her, with increasing intensity toward the end of the movie, she does not look good or happy at all.
Does it have something to do with the man getting a flashback (while leaning on the wrecked car), about he himself shooting the girl?
I would be really thankful to anyone who could clear this up for me. I may be missing something, but don't get what it is.
