Mabel goes through Kimber’s TikTok account and deduces that Ben used Kimber’s anti-aging serum to look younger. As a result, Mabel suspects Kimber of using the serum to poison Ben.

Jonathan advises Charles to find his happy place while singing to stop blanking out.
Meanwhile, Mabel determines that checking Ben’s dressing room could reveal who poisoned him. She tricks Howard into giving her the dressing room keys. On the other hand, Charles freaks about performing the song and prepares an omelet which instantly soothes him, helping with the performance. However, Joy argues that she is Charles’ happy place. Joy also speaks about hurting anyone who tries to cross Charles and uses Ben as an example. Oliver and Mabel visit the dressing rooms and run into Kimber.

On the other hand, Oliver speaks with Charles about the latter’s unhappiness over Joy moving in with him. As a result, Oliver convinces Charles to speak with Joy.
