I think the drugs were more or less left in the parking lot after the shoot out, and I assume Vignali after she fell from the car still alive did get to out Lacombe so he would go down. Also I believe Vincent did live since he had a smile on his face while they rolled him into the ER, I assume he needed a quick transfusion due to blood loss, the rest of his wounds were probably no more than a few cracked or broken bones & a lot of sore muscles.
The real question that I have is, was he really undercover? Or was that an awfully convenient cover to use at a time where he desperately needed someone on his side? His higher-up may have been in with his partner to get the drugs which helps his story yes, but in the beginning after the heist went wrong, him being involved in a murder plus being pretty seriously injured & still not seeing a DR. or going to a hospital all to see his undercover mission through, yea I suppose a cop could be that dedicated.
It all depends on what the viewer prefers since they they left so much unfinished, I guess I prefer a bad guy with good qualities over a straight up undercover narc.
Being from the US & hearing of the remake just makes me ill, Hmm let me guess Jason Statham will play the role of Vincent, yay I can't wait........not really.
