Three Strikes the Vampire LostEpisode 15

Obsessed with his late sister Alex, vampire lord Damian formed an eternal blood bond with Vera in a drunken stupor seven years ago yet neglected his wife and young son all year round. When Elena, a dead ringer for Alex, arrives, Damian dotes on her excessively and repeatedly wounds Vera and their little boy Lucas. After exhausting her three chances for reconciliation, Vera flees the manor with her child, only to return reluctantly to protect her clan. Elena later colludes with vampire hunters and slays Damian. Vera executes Elena per vampire laws, takes charge of the ancient castle with her son, and breaks free from this cursed blood marriage.
