Dracula: The Series

Black Sheep (1x6)

:

An aggrieved husband, Paul Yeager, asks Gustav to kill the vampire who has taken Yeager's wife. Lucard's assistant, Klaus, is the culprit but, astonishingly, Gustav refuses to help track him down. In fact, he warns Klaus of a trap Yeager has set for him. Finally it is revealed why Gustav is acting in such a strange fashion...Klaus is his son, vampirized long ago by Lucard. Gustav traps Klaus in the Helsing family crypt but can't bring himself to kill his son. Instead he imprisons Klaus in the crypt with the help of Lucard, who agrees that Klaus has become unstable.
