Episode 18: The Batgirl: A Knight Alone

Cassandra Cain reached out to help a good man in a shady profession, for he displayed an act of kindness to a child whom was in harm's way.  Cass recognized this and wanted to save the man from sudden death by spiriting him away from his governmental captors with no Bat suit, leaving her identity exposed.  Good thing for Cassandra, she doesn't have an identity; however, facial recognition is still on the table, which leads Batman in rewarding Cass by giving the Daughter of Cain her own place to rest her head.
