However, horrified from her first killing, she fled to the Batman Family for protection. Becoming a claimant of the Batgirl identity, she helped him and Tim Drake protect Gotham. Cassandra has also used other identities, including Black Bat and Orphan.
I'll never take another life. Not even hers. So I'll pretend to go all out... and then I'll die. I don't have to do this. I can still study Batman's method. I can be good enough for the costume. I can be... mediocre. For a lifetime. Or perfect. For a year.
Weak. Without focus you're nothing. And that's what you really always wanted me to have-- nothing. But you never asked me what I wanted. I wanted to read. I wanted to talk. I Wanted a Father. I Wanted a Family. I wanted to belong somewhere!
I don't kill... but I don't lose, either.
