In fact, her answer about Buffy’s current existence was in response to a question from THR about how she feels about whether the show should be revived or not.
Sarah Michelle Gellar has been pretty vocal in the past about not wanting to return to the Buffy the Vampire Slayer universe for any revivals or reunions.
Unfortunately, we’re not likely ever going to see what Buffy Summers is up to in 2017 or beyond, at least in any live-action formats.
She started the answer by saying she believes the show’s heart is tied to Buffy’s formative years and that time of a person’s life, and while it could work in an adult setting, she isn’t sure how.
