On Friday the 13th a witch can tell a mortal about being a witch because at the end of the day they will forget about their secret so Sabrina tells Valerie and Harvey.

Sabrina's anticipation of Christmas gets out of hand: whenever she conjures anything up, it turns out to have been taken away from someone else. Her aunts send her to Dr. Bell, who diagnoses a bad case of "egotitis" by summoning Sabrina's inner child (obsessed with getting presents), and call upon Bob to educate her in the true meaning of Christmas. When Bob is injured in the course of his duties, a horrified Sabrina discovers that he is really Santa Claus - and that she must now take on his duties as a subordinate Claus. Needless to say, Sabrina rediscovers the true meaning of Christmas by distributing gifts that make everyone happy, even Libby.
