Captive Love

Jack Vance kept Melissa Black locked up. She got a knife into him, left him for dead, and ran. Three years pass and she has built a life on the assumption that he stayed dead. The wedding of Jack's younger brother Ethan is where he turns up again, alive, walking in while the ceremony is underway. He goes for the bride first. He shuts his stepbrother inside a mirror. He takes his own father's hand off at the wrist. Whatever brought him back did not bring back any part of him that could be reasoned with, and every person in that family had a hand in what happened before. Melissa is in the room while he works through them.
