Welcome To My So-Called Slayer Life v2 Among other changes in the upcoming season: Willow (Alyson Hannigan) will assume more of a leadership role in the Scooby Gang, as well as returning more to her computer geek roots; Willow and Tara's (Amber Benson) relationship may undergo changes; and Giles (Anthony Stewart Head) will appear only as a recurring character. Anya (Emma Caulfield) will take over the Magic Shop in the wake of Giles' return to England, and there will be no new Slayer called as a result of Buffy's death--the line now goes through Faith, who was called the last time Buffy died, Whedon said. (In response to a question about spoilers on the Ain't It Cool News Web site, Whedon said some were accurate and others were not, but didn't detail which were which).
