He quickly takes an interest in sports journalist student Kaycee Stone while also butting heads with football captain Keller. One day, Ray learns that Fahmarr is not at home with their mom, Tonya, and races back home over the weekend to find that their mother has relapsed and Fahmarr has been staying with a former acquaintance, presumed to be a dealer.
