There are a lot of possibilities as to Paul Kelly's character...One possibility that is likely is that he and Ginny had done the "Badger Game" scam before, therefore his claim to be the "Husband." The "Badger Game" is a blackmail set-up where a person is lured into a compromising situation that is interupted by the lure's partner, who claims to be the spouse of the lure. Money is extorted then from the mark as a way to extricate himself from the embarrasing situation. In this case, a low ranking soldier would not likely be a promising blackmail target, and, as Ginny wasn't in the apartment at the time, the situation wouldn't be embarassing enough to complete the scheme.
Again, this is just a theory, as I can't really see any other good reason for the Paul Kelly character, except as a deus ex machina, to give Cpl. Mitchell someone to talk to in the apartment.
I believe you might be on to something. That badger game sounds very plausible. Hence the fear of the police as they get involved.

loved all the scenes with this guy and also with Ginny. i didn't doubt for a minute the guy was her pimp, i mean, he remarks somewhere she's making money for him., though the badger scheme is an amusing (and possible) explanation as well.
