"I think absolutely you could have a show that revolves around Eliza. She is an extraordinary talent," Whedon tells TV Guide Online. "But [it] would be a very different show. There's a reason why Sarah is Buffy and Buffy is Sarah. What Eliza brings to the show is very different than what Sarah brings. They have very different personas... a very different kind of magnetism.
"Could there be another Slayer?" Whedon continues. "Yeah. But you are talking about a radically different show, and right now I'm happy with this one."
Ironically, Whedon put the scenario to the test in a recent two-part episode when Faith ? who tonight pays a visit to Buffy's ex on his spin-off, Angel ? took possession of her nemesis's body and lived life as The Chosen One. Whedon, however, has no plans to take that experiment to the next level as he expects Gellar will remain on slayer patrol for the foreseeable future.
"[Besides], I don't really think that far ahead," he says. "I'm thinking about the next year and I know Sarah will be here. And I imagine that she will be here for some time after that."
