You're one of Slade's one night stand babies, and he left your mother when she was pregnant with you. But your birth mother also left you on an orphanage when you were a baby, and it didn't end up well. You were adopted and trained by the League of Assassins since you were a child. You ended up working as an assassin.

But one day. Slade's ex-wife, Adeline Kane managed to get legal custody of you, after months of finding Slade's forgotten illegitemate child, you. And she strictly told you to stop doing assassination jobs.

Adeline: Knocks on your door "You better be doing homework!"
