She's either someone that no one takes seriously or forgotten about. Despite being the first Batgirl (or Bat-Girl) and both Kate and Bruce's cousin no one seems to notice her. This is someone that was literally cut open, had her heart stop on her multiple times and STILL had the will to suit up after she recovered.
I'm not saying I want her in DET but it would be nice if she was written well in a bat book. Isn't she in college? Bette hasn't even been on panel with lot of the family. Remember who she was compare to? There's ton of potential being wasted.
