Be nice, have fun!

Frank Reynolds is legal father of Dennis and Dee Reynolds, and the majority owner of Paddy's Pub soon after his introduction in season 2 onward. Frank is a millionaire and often funds and enables The Gang's worst schemes and impulses, just to feel a sense of youthfulness and energy. He was once a successful businessman with a long history of illegal operations and dealings with sordid characters, but chooses to abandon that life and redeem himself after leaving his "whore wife", Barbara Reynolds. It is revealed at the end of season 2 that Dennis and Dee are products of an affair and not actually his biological children. He has since embraced his "feral" nature and describes himself as "fringe class". Despite his substantial financial resources, he chooses to share a decrepit studio apartment with Charlie, where they sleep together on a pullout couch and have a surprisingly affectionate pseudo-father/son relationship. The two have similar interests, such as playing the inexplicable game of Night Crawlers and foraging naked in sewers for valuables. He always arms himself with at least one loaded handgun and does not hesitate to brandish or even discharge one when provoked, and often snorts cocaine as part of his daily routine.
