612

Harry puts poison in Joe's medication, which Angelique orders Barnabas to administer.
== Synopsis ==
: The great house of Collinwood is silent now, for most of its residents are sleeping. But one man is awake. He is waiting for the clock to strike. When it does, he will leave Collinwood and attempt to commit a murder. Meanwhile, in the Old House on the great estate, two frightened people are guarding a dying man, hoping they can save him, unaware of what is happening elsewhere, unaware that this night will probably end with his death.
After Harry sees Barnabas leave the house, he sneaks in and sees Julia asleep in the chair in the drawing room. He sneaks upstairs and Harry puts poison in Joe’s medication. Julia wakes up and heads upstairs calling Barnabas. Harry hears her coming and quickly hides behind the drapes next to the door. Julia Hoffman enters the room, and wonders where Barnabas has gone. She then leaves the room, allowing Harry to follow her out. He escapes apparently through the back door. Angelique summons Barnabas and tells him that he must kill Joe, then bites him. Harry finds Barnabas passed out in the woods. Barnabas prepares to give Joe the medicine against his will.

== Bloopers and continuity errors ==
* In the previous episode when Nicholas gives the poison to Harry, he tells him to go to the Old House and Barnabas will be asleep by the time he gets there. In this episode, when Harry arrives at the Old House, he sees Barnabas leaving and thinks to himself, "He is leaving the house just as Nicholas said he would. Good. It should be safe for me to go in there now."
* Before Julia enters Josette's room at the beginning of Act II, there is shuffling noise and someone whispering off-stage.
* Julia has told Barnabas numerous times that Joe is not to be left alone ever for fear he will be summoned by the vampire or that the vampire will come to him. Yet when she arrives in Josette's room and wonders where Barnabas has gone, she then turns around and leaves the room, knowingly leaving Joe all alone and disobeying her own instructions. In the next episode, Julia again tells Barnabas that Joe "must be watched every minute until morning."
* In Act III, as the scene shifts back to Barnabas and Angelique in the woods, there is squeaking from off-stage, likely the camera moving in its tracks.
* Clarice Blackburn flubs a line: "Let Harry help you so that you'll be sure to be...get there all right."
