Black Cat - Season 1 Episode 3 The Cat in the Dark

Sven accepts the task of rescuing Elena's sister, Eve, and makes an attempt to infiltrate the manor, but without success. Afterwards, Sven learns that Eve is not really Elena's sister, nor is Elena who she appears to be. Later, Sven discovers Eve in a park, and decides to talk with her, and he shows Eve there's a entire world outside the manor she's been held in. Unfortunately for Sven, Torneo's men find them, and forcibly take Eve back to the manor. Sven comes to realize that Eve is not merely a bio-weapon, she's a human being with thoughts and feeling of her own, and becomes even more determined to rescue her, no matter what the cost.
