She is Pinky's sidekick, and there are two rules made by Pinky: Rule 1 is that Pinky is in charge. Therefore, what she says goes, and rule 2 is either obey rule 1 or get a beating. When it's lunchtime, Missy asked Gwen what she has in her hands, accusing Gwen of holding out on them, and Pinky was prepared to beat up Gwen, but Gwen outsmarts the two by throwing her food in their faces, causing a foodfight to happen. Missy tried to tackle Gwen, but instead fell into the strong female prisoner's lunch, apparently infuriating the strong female prisoner that throws her food at Missy, who then ducks, leaving Pinky to take the hit instead. She and her friends tried to attack Gwen from behind, but they get attacked also. When Crabtree fell in the trashcan, she and the other female prisoners cheer, praising Gwen's spell. During their janitorial duty, Missy, along with Pinky, distracted the guards by throwing the mop under the overweight female guard. When Gwen managed to escape from juvie, she and Pinky made their choice to still continue their lives committing crimes instead of reforming so Gwen handed them over to the police by creating a pair of animals made of clay to hold them off until the police managed to arrest them. When the real Charmcaster ended up back in her body, she was sent to the same juvie, leaving Pinky and Missy to fullfill their promise to beat her up for betraying them much to Charmcaster's dismay.
