From a new Georges Jeanty interview, at the Denver Comic Con 2014 : http://hushcomics.com/2014/06/18/denver-comic-con-2014-interview-georges-jeanty/
HC: If you could draw any scene from a Whedonverse show, what scene would you draw?
GJ: Well, why would I do that? I will counter that statement, actually. I did have a conversation with Joss just about this. I will tell you there is a scene that I would have loved to have drawn that never made it on television but should have. When we were doing season 8, I hate to give myself credit for this, but I am the Buffy fans, best friend because I was going to bat. When Buffy slept with another woman, I was like, ‘Nuh-Uh! She’s not going to sleep with another woman. I’m not going to draw that. You need to justify that to me before I can do that.’ When Giles died, “Nuh-Uh! Giles isn’t dead because I’m not going to draw it. You have to justify that to me first.’ So I was really going to bat. I went to Joss at some point and said, ‘Dude, you’ve got Spike coming in season 8. That’s great, we are finally getting the gang back together.’ But I was like, ‘Joss, you realize, if you think about it, Buffy doesn’t know Spike is alive. Because he became alive in Angel obviously and there was never that scene where it’s like, ‘Oh my God’ [referring to Buffy]. He [Joss] was like, ‘Yeah but the fans are really…’ and I’m like, ‘Yeah, the fans want to know that stuff. That’s the stuff that they love.’ He said, ‘No, they can probably assume that Andrew told them’ because of “The Girl in Question” in Angel, they both go and see Andrew. ‘They can just assume Buffy found out from him. ‘ I said, ‘It’s a little bit of a cop out, I gotta tell ya.’ In my mind, over the years, I wonder what that scene would be like. The writer in me, doing Buffy for so many years at that point, I was creating that scene so I could justify it when they did get together and of course subsequently have all these conversations. In my mind, that is what I feel happened in continuity, although it never actually showed up.
