I don't think Pansity is supposed to know about the power of Quentin's portrait either, but the writers have decided to hurry the 1897 story to its conclusion. I guess that's also the reason that they've dropped the pretense that Barnabas isn't the same former vampire Barnabas.
Petofi uses the Hand to force Pansity to reveal how she, Barnabas, and Angelique have helped Quentin get away safely. But she isn’t completely under Petofi’s spell. We have all beat you, she exults, and now Quentin is safely out of your grasp forever and ever! Petofi sends Charles to check her story.
The drawing-room fire is out again as Barnabas tells Charles that Quentin is out too--that is, he's left Collinsport. Barnabas decides to see Petofi.
While they’re waiting, Petofi torments C/P by telling her, Quentin doesn’t even care enough about your to risk his safety. Your sacrifice will be meaningless. She has almost started to believe him when Barnabas and Charles arrive. I’m here with Quentin’s regrets, Barnabas announces--he has left. C/P exults in her hero’s safe escape. Let her go, Barnabas says sternly, and deal with me. Petofi tells Charles to untie her, but makes no move toward pursuing Quentin. Barnabas doesn’t understand, so Petofi explains: I won’t see Quentin again until I arrive in 1969--in _your_ [now all-too-human] body. Barnabas is horrified. You will get used to being nearsighted, Petofi assures him--you will have to. And since you are here, I don’t have to wait for you to fall asleep--I’ll put you to sleep now. C/P jumps up to stop him, but Petofi orders Charles to hold her. Petofi gloats, I look forward to going to the future as Barnabas Collins and seeing all of your friends: Julia, David, Elizabeth, Roger. This is almost more than Barnabas can endure, and he shouts, Petofi, you can’t do this! Don’t bother to resist, Petofi says smugly. There’s no hope left. He puts the Hand on the side of Barnabas’s head. Barnabas falls to the floor.
Charles dashes out the door when Blackwood returns yet again! But Barnabas and Pansity are only too happy to testify against Petofi in Blackwood's parody of a trial. Their testimony is plenty for Blackwood, who tells them to leave: What happens now is between the prisoner and me.
Blackwood starts to retrieve his chain, then spots a can of paint thinner and decides that arson-murder would be a better idea. He closes the heavy red velvet drapes and liberally douses everything with the paint thinner. What are you doing? Petofi asks. I am carrying out the sentence, Blackwood replies. But I haven’t been sentenced yet, Petofi argues. Oh, but you have, Blackwood says. This room will be your execution chamber. You must listen to me! Petofi shouts. There is nothing for you to say, Blackwood replies implacably. You are going to die! And this room will be your funeral pyre! He sets the seascape on fire as Petofi screams, No!
Safe at Collinwood, C/P and Barnabas are sharing a drink and congratulating themselves on Quentin’s clean getaway. Blackwood is a creature from hell! C/P exclaims, still a little shaken. Yes, Barnabas agrees. And I am sure we will have to deal with him after he deals with Petofi. A more appropriate executioner would be hard to find, he opines as he sips (yes!) his drink. Suddenly C/P is puzzled as her second sight kicks in again. She tells Barnabas and we see that the studio is burning, and Blackwood and Petofi are fighting amid the flames. As she watches, the portrait of Quentin reappears as the gesso that covered it is burned away. Quentin! C/P screams. He’s burning! It’s burning, burning!.........
