Whedon explains Anya's death: "I wanted to kill somebody, and I wanted to do it brutally and suddenly and never really pay it off. I wanted a death that was a real middle-of-the-battle death — the opposite of the Spike death, [which was] perfect, noble. And Emma had made it clear that she really was not interested in coming back. I think things with Fox weren't great and she felt ill-used — not by the show. She had a good time making the show, I think. But she was ready to move on. But it was tough [killing her off]. The last shot before we wrapped her was that shot where she gets sliced. And it's very weird to play your death and go, 'Okay, I'm done.'
Interview with Emma in Katz’ book in 2021: “I did ask to die, I could be wrong about this, but from what I do remember the show was on the bubble as to whether the whole creative team wanted to do another season, I think it if was this collective, ‘Yes, let’s do one more,’ that would have happened, but everything was sort of up in the air at that point and I knew that I didn’t want to do another season regardless. I just felt like I had tapped into everything I was going to tap into and I was ready to spread my wings elsewhere and Joss took note of that. So when it was decided that the show would end, Joss came to me and told me that I was going to die, and I thought, okay, that’s pretty cool. And then I read the script and I remember thinking, there’s no real mourning for her. And that felt personal. And I know it was. And my respons to it over the many years no has just been like, ‘Well, you know, it happened,’ or ‘Death, it’s sudden.’ ‘They avoided the apocalypse and I’m sure they cried about me later.’ But at least for what was shot, they didn’t. And that is…that is definitely a creative choice for sure. I can’t look at that any other way other than ‘Go fuck yourself.’ That’s how I took it. That’s how it will always remain, because there really was no story reason for there to be a lack of emotion about it.” -Emma Caulfield Ford
