Winnie's sister comes to visits and falls for Rob. He tries to tell her what kind of a macho guy he is and agrees to go River Rafting with her, only he hadn't bargained on a magical trip to Niagara Falls! Winnie tries to explain to her sister that humans can die, but in doing so scares Rob t the point he won't leave the house.
One of Winnie's spells goes awry when she splits Rob into two personality's. One is very good and the other is pure evil. The worse part is she can't put them back together with magic. The evil Rob then insults one of T.J.'s colleagues who happens to be on he board of a college that Rodger is applying to. Chaos ensues.
T.J. hires Winnie to be his secretary for a short time, just until he gets through with a major client's divorce settlement. Winnie learns however there s a chance for this divorcing couple (Florence Henderson and Robert Reed) to reconcile. She goes against her boss's orders and makes them realize they still love each other.
Jessie anxiously awaits a phone call, to see if her and her friend are excepted into an exclusive girl's club named the Debs. When her friend is accepted, and Jessie's not because they don't know who she is that well, her father suggests she throw a Halloween party to impress them. Winnie who hates Halloween, practices a magic trick on Jessie, accidentally makes her disappear (Winnie's powers get fouled up by amateurs on Halloween). When the ""Debs"" come over, Jessie, now being partially visible eavesdrops on the Debs, and finds out they'll accept her in the group for her cool house to throw parties in, and her hunky brother Robb. Knowing this she backs out of the group, especially when she sees how they snub others not in their group.
