Also, did he contact (not for real obviously, in a movie) STDs or AIDS from that hooker with which the villain forced him to get into unwanted sexual contact and was the AIDS there in any way curable or was it deadly, does anyone know, thanks.
The very fact Blake was alive vindicates Styles, since every "crazy" thing Styles was claiming hinged on Blake still living rather than having supposedly died after escaping from prison (plus Styles' friend retrieved the obsessive clippings Blake made of Styles while in prison.)
The hooker gave him gonorrhea, which isn't nice but can be conquered by antibiotics.
And the whole film sort of came across as action thriller meets attempts at social drama, imagine something like the later film "The Hunt" (2012) crossed over with "Lethal Weapon" (1987) or "The Last Boy Scout" (1991) (SPOILERS - they even went as far as to attempt to frame Denzel Washington's character of running a particularly horrid type of sexual offenders ring as well).
