Interviewer: Speaking of returning characters, could you comment on all the ballyhoo at the end of Angel about having Sarah come back for one of the final episodes and then not coming back and all the speculation that followed?
David Fury: Could you rephrase the question? You mean about speculation as to whether Sarah was coning back?
Interviewer: I heard that you planned on having her come back...
David Fury: We had approached her about doing the 100th episode. Buffy was going to appear in my episode, the episode that I directed, so we put out the offer to Sarah and she politely declined which, I will say, she had her reasons. I think there might have been a death of an aunt or something that she was dealing with but, regardless, I guess Joss kind of felt a little bit put off about the way it was done. There was a perceived notion, on both sides, I can say, between Sarah and Joss of ingratitude for both parties. Joss doesn't feel like Sarah's ever shown the proper amount of gratitude for what he's done for her and her career, and I think she feels the same way. That she feels she was never afforded the credit for Buffy's success and the gratitude from Joss.
I think they're both crazy. (laughs) They were the right people at the right time, it was a great partnership and it created a great series, and I truly think they both recognize this to some extent. But for whatever reason, I think the fact that she declined to do that put a damper on her coming back later.

Also, Joss said he didn't want the last Angel episode to be All About Buffy, which is what would happen if she were to show up. He wanted to focus on the show's regulars instead.
