Angelique: Let me give you one word of advice, Dr. Hoffman. The pursuit of Barnabas Collins can lead to nothing but misery. He is a cold, harsh, unresponsive man."
Dr. Julia Hoffman: Who made him that way?
Quentin Collins: Of course a woman is going to kill me. I wouldn't have it any other way.
Carolyn: I don't want a sedative! I want Jeb.
Quentin Collins: On your way to grandmothers house and low and behold who should you meet but the big bad wolf.
Angelique: You wish you'd never met me. But you did. And nothing can change it... Come to me. I command you to turn around. Look into my eyes. Deep into my eyes. You have no will of your own. You cannot resist me.
Maggie Evans: I know what Barnabas Collins is... Joe, we haven't got time to talk. We've got to escape. We've got out of this town.
David Collins: I wonder why Willie went in the secret room? Maybe there's something in there he doesn't want anyone to see-maybe someting... horrible.
Barnabas Collins: I didn't say she was dead, I said I killed her.
Quentin Collins: If only we could find a way of telling the truth without anyone knowing what actually happened.
Barnabas Collins: I said you were my friend, and how I wish that were the truth. But I am past the point when friends are possible. I'm sorry.
Answer: It's probably episode 193 (even though the slate at the beginning says 58). It's the episode with Sam demanding that Roger return his paintings. Three clues from the Dark Shadows Companion and from the comments of Kathryn Leigh Scott and Louis Edmonds all agree that 1) Scott is in the episode and is done for the day prior to Edmonds without his pants; 2) Edmonds is wearing a smoking jacket, and 3) Edmonds is leaning on the mantle (which is actually the cabinet where the liquor is, because the fireplace mantle is too high to lean on and the bench in front of it prevents getting too close to). There are several "breaks" in the lengthy scene where commercial were probably inserted, and all of the shots are above the waist. The previously mentioned episode 54 has Edmonds in a suit and Scott isn't in the episode; episode 54 doesn't have Edmonds or Scott; and episode 86 only has Edmonds in a suit.
Lou Edmonds was a consummate actor and would not forget that he had a lengthy scene to perform. Rather, in Episode 86, Edmonds more understandably forgot that he had to perform one last 15-second scene (a simple toast). He had removed his shoes and pants before he was reminded of the final, brief shot, and he hurried back to complete it.
