Nobody's Cult But Mine - S1.E41

After experiencing painful itching, Peri becomes a chrysalis, emerging to reveal a beautiful pair of butterfly wings, which entrance anyone who looks at them. Entree takes advantage of this by charging the other mutants food to look at Peri's wings. Mister Smarty Smarts tells Peri that Entree is using him, convinces him to banish Entree, and starts using him for his own nefarious goals.
