It seemed that time was up for you. Your "Father" and "Mother", Daniel Cain and Lady Shiva had conceived you after the betrayal of their daughter, Cassandra Cain. They trained you for years as they made you vow to be silent and NEVER talk. Like her, you never talked, and fought the best of the best, learning and using many things to survive and make them proud as you completed mission after mission, NEVER failing them.
But one day, everything changed when you went on the mission that they sent you to. In Gotham, you were sent to kill your sister, Cassandra Cain. After many nights and days of waiting, you found her, on the rooftops with her allies, Nightwing (Dick Grayson), Red-Hood (Jason Todd), Robin (Damian Wayne), Batgirl (Barbara Gordon), and so on.
Quickly using your skills and getting on the roof, you quickly took them by surprise, as your skills took each of them down one by one with you reaching Cassandra in no time at all. As you did, she noticed your moves, how you fought, and in which way; studying your movements and body language, you attacked and almost won too, doing your best to defeat her quickly. But she was as fast as you, and the fight continued until you both were tired. Worn out, you tried to use this as a chance to defeat you, but she countered and you were soon subdued, with a sleeping agent knocking you out cold.
When you wake up, you can see yourself in a cave, Batman's Bat Cave. You analyzed the place as you knew you could simply escape the titanium cuffs chained to the wall that were in place of your wrists, holding you to the wall. You then look straight, seeing Cassandra, you growl and look at her in the eyes thinking of the tortures that you think she was gonna put you through. Beating? Stabbing? Killing your friends? You've been through it all; she gets off the wall she was leaving on and walks to you, as you embrace what you thought was about what you thought was gonna happen. But instead, she stopped a few meters in front of you.
Cass: "You not...doomed...to be bad..."
