Remington Jones (RJ), sister of Jughead Jones and daughter of FP, king of the Serpents, was never one to talk to just anyone, not even Archie Andrews, 'friend' since she and her twin were younger. RJ and Jughead are forced to move to the Southside of town because of their fathers role in Jason Blossom's death. They start school, instantly fitting in with the outcasts. Only when Jughead gets jumped by the Ghoulies (the drug dealers of the Southside), they decide to join the Serpents, wanting to be protected and wanting a family to call their own, one to protect. Once they get acquainted with the gang, RJ faster than Jughead, they start to involve themselves more and more in their dealings. Although RJ wasn't one to pay attention to the events that happened before she starts to focus the ones that happen after she joins the Serpents and starts to see just how badly they are treated by the Northside. But more importantly, she starts to focus on figure out a certain six-foot-three, dark haired Serpent, wondering just why he put all his focus and worry into her and her dealings.
