After Roger drives her to tears, Carolyn sets a new record for the fastest departure from Collinwood--she leaves the house by the front door (carrying a suitcase) and less than five seconds later we hear her car driving off.
I agree, MT. That was a missed opportunity. But later, Barnabas returns to the Old House--and finds Carolyn calmly waiting for him with the stunning announcement that she is volunteering for the experiment. Apparently when Nicholas hypnotized her, he telepathically informed her of how Adam came into being. She seems to know but doesn't mind.
Meanwhile, Willie lights a cigarette off one of the candles in the secret room at the mausoleum as he tries to tell Maggie that the police will think she's crazy if she tells them about Barnabas. But she remembers everything--including that Willie helped Barnabas. She suspects Willie of being "like Him." Willie reaches out his hand so that she'll feel his human warmth, but she promptly faints, and he's able to leave without revealing the mechanism for opening the panel.
While Barnabas is thinking over everything Carolyn said, Willie bursts into the Old House in total panic. Barnabas doesn’t let Willie get a word in. Coldly he tells Willie, Adam tried to kill Vicki--and if Vicki had died, you would have been responsible. Barnabas makes one more attempt to strangle Willie, but Willie shrieks, Barnabas, please listen to me! Maggie remembers the Old House, she remembers everything--what you were! If she tells the police they’re gonna come here! They’re gonna get you, Barnabas, and they’re gonna destroy you!
