Fluttery heiress Millicent Collins has been staying at the great estate of Collinwood as the guest of her second cousin, haughty tyrant Joshua Collins, and Joshua’s wife Naomi. Today, Millicent has news for Joshua and Naomi. She has agreed to marry naval officer/ sleazy operator Nathan Forbes.
Joshua and Naomi are stunned by this announcement. Millicent had been obsessed with avenging herself on Nathan for some time, ever since she discovered that when they became engaged on a previous occasion he was already married. But now Nathan has apparently rescued her from an attempt on her life by Joshua and Naomi’s son Barnabas, and Millicent no longer holds Nathan’s late wife against him. For their part, Joshua and Naomi are quite sure that Barnabas did not attack Millicent, and suspect that the whole thing was a ruse by Nathan. Joshua forbids Millicent to marry Nathan, and threatens to have her declared insane if she tries to go through with the marriage.
Nathan shows up. He tells Joshua that he and Millicent will not marry without his consent. At that, Joshua agrees to meet privately with Nathan. Joshua withdraws. Millicent tells Nathan that she wishes he had not told Joshua that they would accede to his demands, and Nathan tells her that he has the situation in hand.
In this scene, played out in the entryway and seen from a point of view inside the coat closet, director John Sedwick makes some clever use of a portrait. The portrait, which hangs in the drawing room in the parts of Dark Shadows set in the 1960s and which is identified by fans as that of Joshua,* at first mirrors the furious Joshua as he looks at a sheepish Nathan:
As Nathan begins to make his play, his face overlaps with the portrait, creating the momentary illusion of a kiss. Joshua is startled by Nathan’s assertiveness.
When Nathan and Millicent are alone in the entryway, Nathan stands where Joshua had stood. The portrait now mirrors him as before it had mirrored Joshua, suggesting that he is in the process of taking Joshua’s place.
Joshua and Nathan meet in the study. The study was a set that first became prominent during a blackmail story that played out from March to June of 1967, when Dark Shadows was set in contemporary times. Then, seagoing conman Jason McGuire had established the drawing room of the great house at Collinwood as his base, and the study was a place to which his victim, reclusive matriarch Liz, would retreat, only to discover that Jason had even more power over her than she had thought.
Now, the show is a costume drama set in the 1790s, and Nathan is coming to resemble Jason more and more strongly. Joshua is in Liz’ place as head of the household. When Nathan starts talking about a secret he is sure Joshua very much wants to keep from public view, Joshua at first has no idea what he is talking about. He assumes, to his scornful amazement, that Nathan is taking a shot in the dark, hoping that Joshua might have some shameful secret and gambling that he will be able to convince him that he is in a position to expose it.
Nathan shows Joshua Barnabas’ cane with its distinctive wolf’s-head handle. He assures Joshua that Barnabas dropped it when he attacked Millicent. Joshua does not believe that Barnabas had anything to do with the attack on Millicent, for the excellent reason that he knows Barnabas is dead. Joshua cannot share this information with Nathan, since he has insisted on lying to everyone and claiming that Barnabas is alive and well and living in England. In fact, Nathan and a henchman of his did fake the attack on Millicent, but Barnabas’ situation is not so simple as his parents believe. Unknown to them, or to Nathan, or to any of the Collinses, Barnabas has risen from the dead and now preys upon the living as a vampire.
For his part, Nathan knows that his one-time friend Barnabas is in town, and that he is responsible for the many killings that have recently taken place there. He believes that Barnabas is alive and has become a serial killer, and that the family spread the story about England to cover up this new hobby. Nathan presses more information on Joshua about sightings he and others have recently made of Barnabas, and about evidence connecting Barnabas with the murders. Since Joshua himself had seen that Barnabas’ coffin was vacant in #422 and occupied again in #428, he cannot simply dismiss Nathan’s story. Nathan tells him that Barnabas is hiding in the Old House on the estate, and Joshua decides to go there.
While Joshua prepares to go, Nathan makes himself at home in the great house. He pours himself a drink in the drawing room, as Jason McGuire often did. We cut from the shot of him doing that to the study, where Naomi pours her own drink. Longtime viewers, remembering the miserable state to which Jason reduced Liz while blackmailing her, will be apprehensive that Nathan’s blackmail of the family will bring the alcoholic Naomi to an equally profound despair.
At the Old House, Joshua encounters much put-upon servant Ben Stokes, who tries to keep him from going to the basement. Ben has reason to hate Joshua, and often expressed such hatred earlier in the 1795 flashback. But there is no hatred in him today. He sincerely wants to spare Joshua the sight that he knows awaits him downstairs. But Ben is powerless to stop Joshua, and sadly watches him go through the cellar door.
Joshua finds Barnabas’ coffin at the foot of the stairs. The lid opens, and Joshua sees a hand under it wearing a familiar ring. As Jason had inadvertently pushed Liz to discover a secret she had herself not dreamed of when he directed her attention to the basement of the great house once too often, thereby losing his power over her and leading to his death at Barnabas’ hands, so Nathan is about to change Joshua’s awareness of the situation in ways he himself could not have anticipated and which are likely to lead to his own downfall.
