That's So Raven (2003)

S2E7 Close Encounters of the Nerd Kind

Raven is initially reluctant to attend a convention celebrating Devon's beloved series, but a troubling vision of him snuggling with another girl compels her to join. Along with Chelsea and Eddie, they decide to invade the convention together. On another front, Willam mistakenly believes that Cory possesses psychic abilities, a misconception stemming from Cory’s silence about Raven's vision regarding Willam's missing rabbit. Seizing the opportunity, Cory plays along, soliciting money from attendees by claiming he can communicate with their pets.
