My Fair Vampire Dracula: The Series : Season 1 Episode 16

Gustav's best friend, a fellow vampire hunter named Frederick Rilling, claims that people at his old age home are being killed by a vampire. He asks Gustav to help him destroy the one responsible. Meanwhile, Lucard tries to play Pygmalion to an airheaded Galatea named Amber Santana. Things are not as they seem, however: Amber is in fact a dedicated vampire hunter who hopes to kill Lucard, and Frederick is an ancient vampire who hates what he is but is unable to control himself.
