Chris cuts short a date with Carolyn to go back to his room, where he turns into a werewolf and later attacks a waitress at the Blue Whale.
== Synopsis ==
: A little girl spends her first night in the great house of Collinwood, a night of strange, weird discoveries, for she finds an ancient telephone, its wires hanging loose. But when she picks up the receiver, she hears a faint voice from the past, a voice which orders her to come to him. She knows not why.
David and Amy hold a seance to contact Quentin; however, they don't reach him. Chris comes to see Amy to tell her he will not be able to take care of her. Carolyn steps in and volunteers to keep Amy at Collinwood. Carolyn and Chris have a drink at the Blue Whale, where Chris sees the mark of the pentagram on the waitress. Later a werewolf breaks into the Blue Whale and kills the waitress.

== Background information and notes ==
=== Production ===
* There is a tape edit when Carolyn and Chris are at the Blue Whale, right after Carolyn asks if he will be able to stay in town for a week or two and Chris says, "I don't know." There is another one before Chris turns into a werewolf, after he looks at his face in the mirror in his hotel room at the Collinsport Inn and then walks over to the window to look at the moon. Also, the shot when Chris turns into a werewolf is edited in. 
* First appearance of a werewolf in full makeup.
* Alex Stevens is uncredited for his role as the werewolf but is instead credited as "stunt coordinator" in the middle of the cast list.

=== Story ===
* A red upside-down pentacle appears over the the barmaid's face when Chris looks at her to pay his check. This is a sign of satanic ritual; as in the practice of , the pentacle is right side up, though it is unclear if the writers knew of the significance of or difference between an upside-down pentacle and one that is right-side up. This is also a reference to the 1941 Universal Monster film The Wolf Man, in which a pentacle appears on next destined victim of the werewolf.
* It's been a long time since Carolyn last met Chris.
* Chris Jennings meets Victoria Winters Clark for the first time.
* There is a sitting room next to the room Amy is staying in.
* The current season is winter.
* GHOSTWATCH: Quentin's ghost talks to Amy on an old telephone. David and Amy hold a seance to contact Quentin.
* TIMELINE: 5pm: Carolyn and Chris at the Blue Whale. Day 252 begins, and will end in 643. 1am: Chris attacks the Blue Whale waitress.
== Bloopers and continuity errors ==
* Just after the opening credits when David finds Amy has returned to the west wing, the lightning effect studio lights are visible twice, first through the hinge side crack in the door after he enters and then again more clearly through the door opening after they have both left the room.
* In Act I, shortly after David and Amy return to Amy's room, a boom mic shadow can be seen moving in the upper right-hand corner of the screen on the bed canopy.
* David says, "I know what we can do," and Denise Nickerson, sensing a long pause [or forgetting to say her line], asks, "What?" After another long pause, David Henesy delivers the line.
* David Henesy has a bit of trouble lighting the stick on fire from the fireplace, and then when he does light the candle with the stick, he places the stick on the fireplace, but it's still on fire. Denise Nickerson blows it out.
*When the door to Amy's room mysteriously opens during the seance, a black figure is seen standing some distance from the door, making it seem as if the door opened itself. Of course we immediately learn this is Victoria. But if she was the figure standing away back from the door, how did the door open?
*When Act II starts on the establishing shot of Collinwood in the morning, the end of Act I's musical sting is heard briefly before the new music cue begins.
*When Carolyn takes Chris upstairs to talk to Elizabeth, the music cue for the next scene starts too early. When the scene shifts to David and Amy in Amy's room, the music cue starts over.
* A boom microphone shadow can be seen over Carolyn's head as Victoria takes Chris upstairs to see Amy.
* David Henesy flubs when he says, "Don't feel too bad, Amy. I don't like to feel my -- I don't like to see my relatives." He flubs again when he says, "...you'd be... you'd like..."
*When Amy runs to Chris when he enters her room at Collinwood, he picks her up in his arms. He accidentally hikes her dress up a bit, and you can see her underwear.
* Chris comes to Amy's room at Collinwood, and Victoria and David leave the room. When Chris starts to talk to Amy while he's holding her hands, he clearly forgets his line. He moves her over slightly past the bed and looks up, clearly trying to see the teleprompter for his next line.
* The clock at the Blue Whale says 1:00 while Carolyn and Chris are there, and Carolyn notes that it's getting dark early. The clock is set for the later scene when the barmaid is closing up.
* Carolyn orders a daiquiri. The waitress brings a glass of clear liquid. Strangest looking daiquiri you'll ever see.
* The song playing in the background when Carolyn and Chris are at the Blue Whale ("No. 1 at the Blue Whale") is presumably from the jukebox, but it's odd that it stops in the middle of the song just before Carolyn and Chris toast each other.
* When Chris notices it is getting dark outside, he looks at his wrist as if to be looking at a wristwatch. He doesn't appear to be wearing a watch, however.
* When the scene shifts from the Blue Whale to Chris's room at the Collinsport Inn, Don Briscoe is seen standing still, holding the door open, waiting for his cue to close and lock the door. Also, when he does so, the wall to his right shakes.
* Chris goes back to the Collinsport Inn, to the same room he slaughtered the clerk in. It would appear that Housekeeping has cleaned the room and returned it to the disused state it was in previously. [Addendum: Actually, the room has been tidied and straightened up and the junk previously seen has been removed, though the same old furniture remains.] There are no bloodstains and no sign of the remains of the clerk. (Possibly Chris covered up all the evidence.) Also noticeably absent in the episode is any discussion of the man having gone missing.
* Someone is talking in the background as Chris is chaining himself to the radiator (it sounds like they're saying, "Hey, wait a minute").
