Professor Stokes, Tony and Julia hold a seance to contact Reverend Trask and use his spirit against Cassandra.
== Synopsis ==
: Night over Collinwood, a night which will affect all who live here, for the witch has placed a man under her spell, a man helpless to resist her evil will, and sent him to murder someone she knows to be her greatest enemy, her most dangerous threat.
Stokes realizes that Tony tried to poison him with the sherry, so he switches the glasses. Tony collapses, and Stokes calls in Julia Hoffman to tend to him. They both realize that Tony is in Cassandra's power. Tony tells Cassandra that Stokes is dead, and then Stokes, Julia, and Tony hold a seance to recall the spirit of Reverend Trask to exact revenge on Angelique.

* TIMELINE: Day 212 begins, and will end in 515. 12am: Cassandra wonders where Tony is.
== Bloopers and continuity errors ==
* In the teaser, while Professor Stokes is looking at the cross, he averts his eyes from it, seeming to be looking off-stage for his cue for the scene to begin.
* As Julia sits down on the sofa at the start of Act 1, the boom mic briefly dips into the shot.
* Julia says she has known Tony for a long time, but not much time has passed since she first encountered him when she asked him to hide her notebook.
* When Julia sits on the couch after treating Tony and packing her medical bag, she accidentally reveals the top of one of her stockings and a garter belt strap.
* When Julia and Professor Stokes talk about Ben Stokes and the "original" Barnabas Collins, Grayson Hall misspeaks the word "ancestor" as "anstestor."
* Ben Stokes had pretty fancy handwriting for somebody who just learned the alphabet, and no mistakes!
* After Professor Stokes tells Tony he knows Cassandra Collins, someone says something off-stage.
* Thayer David walks into the frame wearing a robe from the left side during the end credits. He realizes it and circles back the way he came.
