Jekyll and Hyde (2015)

S1E8 Moroli

Though Robert has no desire to confront the creature preying on affluent young men, the clues he uncovers prove too intriguing to ignore. His investigation brings him face-to-face with a stunning vampire who reveals herself as his sister, Olalla. She also shares the startling news that Dance is still alive and being restored by eel-like beings. Distrustful of her intentions, Robert devises a challenge: if she can transform into a Jekyll, he will accept her claims as truth.
