About
Another newcomer from Ms. Stevens' dancing choir, Esther bears a resemblance to Kevin Stoley, whom many fans believe she is related to, and is sometimes in the back of Mr. Garrison's classroom. She worked with Craig Tucker on the egg project and was interviewed by the South Park Gazette about youth narcissism, which she is an expert on because she is a young narcissist herself.
