Well, looking at the backstory she blows wherever the wind leads her - and she is found her way to the same area. 

What exactly is it she does with her time? I suppose it depends on her personality and if she has any short or long term goals she is working towards. 

If nothing in particular jumps out, then perhaps she is simply drinking in 'the cracked glass', the place where the characters all just so happen to be heading. 

Or maybe something involving Redding and his drugs/prostitution/business? 

Looking for a merc? Dallen has such a business. 

Or something else. Hopefully this'll give some ideas to start with either way.
