The spirit of evil sorcerer Count Petofi has taken possession of twelve year old Jamison Collins, much to everyone’s consternation. David Henesy spends most of the episode mimicking Thayer David’s Petofi, with hilarious results.
We see Jamison’s favorite uncle, Quentin the Satanist, trying to cast a spell to break Petofi’s possession of Jamison. As he always does when he is calling on the dark powers of the unseen realms, Quentin gets very fervent. We pan to Jamison/ Petofi, standing next to Quentin in a state of utter boredom, asking if Quentin will bring him a glass of mineral water once he’s “finished with all the mumbo-jumbo.”
Twice, Jamison/ Petofi pretends he is not possessed, but is his usual preteen self. He does this in order to trick people into letting him kiss them, which is how Petofi’s power spreads to them. This gives Mr Henesy the challenge of showing how Thayer David would play Petofi playing Jamison. That’s the sort of thing an actor needs a director’s help to pull off. Unfortunately, the woeful Henry Kaplan was at the helm today, so we discover that Petofi’s imitation of Jamison sounds exactly like the original, who is in turn uncannily like Jamison’s grandson David Collins and his great-great-grandfather Daniel Collins, who are also played by Mr Henesy.
Those whom Jamison/ Petofi kisses reveal their “true selves.” So maidservant Beth reveals that she was under the power of Jamison’s distant cousin, vampire Barnabas Collins. When Jamison’s father Edward passes this word along to Quentin, Quentin tells him is going to confront Barnabas. Edward has been hunting Barnabas, and by saying this Quentin implies that he knows where Barnabas is and that he has been helping to hide him. For some reason, Edward only smiles in response to this revelation.
Petofi wears a prosthesis in place of his right hand; Edward finds that Jamison’s right hand has also been replaced with a prosthesis. After this horrifying discovery, Jamison/ Petofi kisses Edward. Quentin returns shortly after, and finds that Edward does not recognize him or know the name of the house. Edward identifies himself as a newcomer to the area, and says that he would be glad of any work the family might hire him to do. Evidently his “true self” is a guy who needs a job. Since he has not inherited any assets or accumulated enough to live on, I don’t suppose we can disagree with whatever force it was that declared this to be Edward’s reality.
