Season 2, Episode 19 - "When Teens Collide"
5 March, 1998
As Sabrina and her aunts get ready for their daily activities, they get a surprise when sunspots cause molecular instability in the Mortal Realm. After Zelda's arm gets attached to Hilda's body and a black hole forms in the kitchen sink, the aunts warn Sabrina to be careful while at school since they don't know how she'll react to the sunspots. At first Sabrina has mild reactions when dealing with the molecular instability, but when she bumps into Libby, the two girls swap personalities. The first one to notice the change in Sabrina is Salem, when he finds her studying the self-centered spells in the magic book. To make matters worse, he suggests to her to take over the world, resulting in Sabrina being arrested by the Witches' Council. After Salem realizes the sunspots are the reason for Sabrina's personality change, he rushes to the Other Realm to save her.
