Reginald is a vendor, making a living selling weapons from his little shop in the post-apocalyptic wasteland. Despite the utter bleakness of his surroundings, he's keeping a stiff upper lip and soldiering on. He is eager to please, with an extremely obsequious and subservient attitude.

I picture him as a middle-aged man with a very posh RP British accent and a foppish attitude, like the kind of person who would roll his Rs, wear a monocle and sip tea with his pinky finger extended.
