I would like him to go through a journey where he starts in one place psychologically and ends up in another, allowing him to go through some kind of change," Marsters explained. "I would like him to be the lead. I heard from some people that they were thinking of doing a Spike/Illyria piece and I need to talk to them and say, 'I'm really interested in doing the character as a lead, but I've done him as a sidekick.' If they write an Illyria piece with Spike tagged on, I probably won't do it.
I love Amy Acker and would love to shoot with her, but there's nothing for me to prove by doing it with her," he continued. "It has to do with theme. What is the theme? Who is the character the audience is supposed to identify with? The trick of a story is that you bring the audience on a vicarious journey and you make the central character someone they want to be, so they see themselves through the eyes of that character. Illyria could be all through it. They could be talking to each other in every scene, but thematically it's got to be Spike's story. That's brutally honest, but it's the way I feel."
