adam because, he shoots him, then its brians shot, so charlie has a 50/50 chance of brian shooting him, (more likely than not as charlie didnt shoot at brian)

then its adams shot and again there is a 50/50 chance of shooting charlie as brian has also shot at him

ooh forgot to mention, because charlie is a shit shot he may miss adam and if brian shot at him and hit (more likely) than adam would want to get him back !



just one that pooped into my head real quick may be well wrong ha ha
