Tabitha receives a visit from her mortal brother Adam. Meanwhile, she falls in love with her co-worker Cliff and reveals her identity as a witch to him.
Actually this first pilot had Adam as warlock trying to convince Tabatha to use her powers. In the show Bewitched for the first few years the name was spelled ""TabAtha"" with an A in the credits. It later was changed to an ""I.""
