Identity
While neither character has been explicitly said to be Clyde's Sister, either of the following may be her, until an image is added by the admins:
- A teenage girl voiced by Trey Parker can be seen in the deleted scenes for "Reverse Cowgirl" singing at Betsy Donovan's funeral - it's possible this is Clyde's sister.
- Clyde is also seen sitting next to an older woman with brown hair in all-black at the funeral who might be his sister.
