[quote=@Drake Baku]but yeah I make a character as a whole, so while there is space to change some small stuff, changing anything of the important stuff would break the picture[/quote]
If that's how you feel, and aren't really willing to change anything. I don't see how I can help you. If you want advice how to build a well balanced character for this type of setting, (as you said this isn't a Marvel Comic), I'd be willing to help. Just PM me. Other than that, I don't think I have anything more to add.

Also, so far Piper only knows Naomi and maybe Jack through the Fixers. :) It's quite possible that everyone might know of the Fixers and is somehow tied to her through that way. I would not be adversed to that.
