After starting the Rita's Sister assignment, the next time you enter Flux a cutscene plays showing Schells being thrown out by the club's bouncer. Schells explains that he is trying to perfect his "system" for predicting the outcomes of Quasar machines. In order to do this, he has been using a device which emits a signal that tampers with the machines, increasing his odds of winning (as Schells needs more data on winning instead of losing). Not surprisingly, Flux's owner Doran accused him of cheating and tossed him out.
