S2E20 Mesmer's Bauble

A shy record-store employee is infatuated with pop star Angelica when he inadvertently witnesses a jewelry heist. During the chaos, he picks up a cursed pendant that once belonged to Dr. Mesmer. This necklace grants him the power to make anyone do his bidding simply by mesmerizing them. His initial wish transforms him into a more appealing version of himself, and he then desires Angelica's affection and proximity. However, he finds these accomplishments unsatisfactory and ultimately wishes to become Angelica herself. His transformation is successful, but Micki and Ryan, hot on his trail, catch up with him at a concert and reclaim the pendant, reversing all its powers.
