Driscoll Connor (commonly referred to as F8 or the Infinity Killer) (Brian Chamberlain) is the main antagonist of the Dexter Alternate Reality Game. This killer started a cycle after a situation dealing with the Roulette Killer back in his younger years, leaving a sideways "eight" at every crime scene...also known as the symbol for "Infinity". Dexter Morgan appears to have little to nothing to do with finding this killer, that job is left to players of ARG as well as Dee Pratt, the Serial Huntress.
