Reby would love some connections right now. :) Need someone to interact with in the game currently.
It's quite possible that she knows the handsome, new cop is single from word of mouth. I am sure that she may have overheard someone talking. Who knows, she may be one of those people that happens to be in a certain spot when he's doing a patrol or is on break
Sadly, he'd likely not have noticed her, since most people stare at cops anyway and he'd gotten used to it.
Nothing like starting a rumor mill after all!
