The actress retired. The character didn't.

In order to pursue a serious career in acting, Carmela Hayslett hangs up her top hat and retires her popular horror hosting personality, Roxsy Tyler.

Meanwhile, locked in a little box somewhere in Hayslett's psyche, Roxsy Tyler is alive, well, and ready repossess the actress's body!
