Adam Stephens

 is the warlock son of Darrin and Samantha Stephens. Tabitha is his older sister.

Background
Adam is taught to be a warlock by his grandfather Maurice, much to his parents' dismay. Adam was born in 1969. In the spinoff series, Tabitha, he is a mortal like Darrin instead of a warlock.

In the episode "Adam, Warlock or Washout?", it is discovered that Adam has supernatural powers. At first, Adam was thought to be a normal mortal human. He tested out as "mortal" during the same test that had proved that Tabitha was a witch. Maurice, cast a spell upon Adam by using a shell. The "shell" spell ended up releasing Adam's latent powers that were there the entire time. Adam then immediately began his wishcraft - just as Tabitha had done when her powers first awakened.

Serena
Although they call her "Auntie Serena", Serena is really Tabitha's and Adam's first cousin once removed, because she is Samantha's first cousin, not her sister.

Bewitched Sequel
In 1976 a spinoff about Tabitha was produced. In the first Tabatha pilot, Tabatha is in love with a mortal man, just like her mother was, but instead of a meddling witch of a mother-in-law, like her grandmama Endora, Tabitha has a meddling warlock brother. Adam pops in and out, trying to convince Tabitha to leave mortals alone and to pursue her life as a witch. This pilot was bought, but before the series was produced, the entire premise was changed.

In the new Tabitha pilot (1977), Adam is a mortal, just like their father, and he tries to convince Tabitha to live a normal, mortal life. A new witch aunt was also added, Aunt Minerva, who dislikes Adam's mortal ways and tries to get Tabitha to be more like a witch.
