Adam attacks Willie and Maggie; when Sam comes home, Adam attacks him as he is trying to protect Maggie.

Synopsis

On this night, those who reside at the great house of Collinwood are safe. But near the Collins estate, in the town of Collinsport, there is one whose life is in danger, for a chain of events have been set into motion, and they will end in a burst of violence and a sudden death.

Willie stumbles into the Evans Cottage and Maggie is shocked that Joe has beaten him. She tends to him but they are interrupted by Adam, who attacks Willie. When Maggie tries to pull Adam away, he turns on her. Just then Sam arrives, and tells Maggie to get behind him. Sam tries to reason with Adam, and tells him that he and Maggie are both his friends. But Adam misunderstands and attacks Maggie. Sam defends his daughter and Adam knocks him down. Sam ends up in the hospital seriously injured. At the Old House, Julia is wondering where Willie and Barnabas are. She hears a woman sobbing in the basement. Julia goes downstairs and sees Josette's ghost crying near the wall in the basement where Barnabas is trapped. Julia suspects that Barnabas may have been walled up there by Trask.

Background information and notes

Production

Story

• GHOSTWATCH: Josette's ghost sobs and then appears to Julia.
• INTERNAL MONOLOGUE: Adam: Afraid x 2; Julia: Where is Willie and Barnabas?
• SEDATIVE: Willie gives Maggie some pills so she can sleep.
• TIMELINE: Day 213 begins, and will end in 519. 1:50am: Maggie and Willie return from the hospital.

Bloopers and continuity errors

• In the teaser, Grayson Hall as the narrator says, "...a chain of events have been set into motion, and they will end in a burst of violence and a sudden death." However, there is no death at all (and certainly not a sudden death) in this episode. Sam will eventually die the next day (in the passage of story time; it will be several episodes of screen time), but it will take some time.
• At the start of this episode, Willie comes flying through the door and lands in the middle of the Evans cottage in a rust-colored jacket. However, at the end of the previous episode, Willie entered after Joe had beat him up and stayed near the entrance in a beige-colored jacket.
• Adam and his clothes are surprisingly clean and neat considering he has been hiding out for several days now.
• Between the end of Julia’s internal monologue (“Something terrible. But what? What?“) and before Josette starts crying, a voice can be heard in the background saying what sounds like “damn.”
• Julia says Barnabas has been bricked up behind the wall for three days. However, the on-screen passage of time indicates only one day. Also, it is unlikely that Barnabas would be able to survive three days without food and water and presumably a limited amount of oxygen in the small alcove. [Addendum: Water and oxygen would be the primary threats to life. A person can live without food for a long time.]
• It appears the ghost of Josette was superimposed on the picture too soon, as Julia looks at it for several seconds before reacting as if it suddenly appeared.
• During the closing credits, a shadow in the hallway to the right of the fireplace in the Old House parlor can be seen moving right before the Adam/Robert Rodan credit appears.
