I thinck it means that he's a concerned neighbor of a working gal. Don't know how he found out, but seems he's been around here a while and maybe he has seen her ads / avatar here.
It also sounds like the asshole she's with is beating her, and he's about to put an ass beating on the woman-beating asshole next time the cops don't do anything. Can't say anything bad about some guy that looks down on woman-beaters.
It also seems he doesn't care for the term African American. Can't say that I do either.
Seems he's up and awake when she comes in at night. I'm not saying he's stalking her; I'm just saying he notices it when she comes home.
Anyway, that's just my take on the dealio.
And, Zhivago is a sexy Mexican something from South America.
