The Witches of Pennbrook

Synopsis
When Jack starts dating a weird girl, Millie, played by Candace Cameron, Eric is suspicious. What's even more suspicious, not only is Millie a witch, but she has a weird fascination with their apartment. Millie keeps making Jack blow off his plans with Eric, and it is making Eric upset. When Eric calls Jack on it, Jack only gets defensive.

Things get weirder when Eric walks onto the balcony and sees Millie chanting in tongues, then speaking to Satan. He tries to tell Jack, but Millie tells Jack that Eric tried to kiss her and Jack immediately sides with her. It is then that Jack drops a bombshell: Millie is moving in. The next day, as Millie is moving in, she tells Jack of her plans for a Halloween party.

Eric seeks Feeny's advice, and Feeny tells him that he should try to work it out. Eric thanks Feeny and is off. Over at his apartment, though, the Halloween party is in full stride. Dozens of Millie's friends are wandering around the apartment, making spooky sounds. Jack seems uncomfortable, but Shawn is having a blast. Suddenly, all of Millie's friends take the Hunter brothers and tie them to the banister. Mille then reveals her plot: it was written that Satan's tail would appear on their balcony, and a Hunter needed to be sacrified. Just then, Eric shows up, and he's done his reading on witches (Witchcraft for Dumb-Dumbs). The light beam suddenly appears, striking Eric on the rear end but otherwise doing no damage. Eric makes Millie & her minions leave because they've been foiled, then unties Jack. The two apologize to each other then go out to a party, leaving Shawn alone tied to the banister.

Meanwhile, Cody surprises Kelsey with plane tickets to Pittsburgh to visit her parents, but Topanga reveals her fear of flying. Cody says he'll help her through it, but becomes just as scared as her when the pilot, Dexter Jorgensen, reveals that Eric had tutored him and he thought Eric was really smart. Somehow, though, Kelsey conquers her fear anyway and Dexter lets her fly the tiny plane herself.
