Regarding the Buffy finale, he says that Spike died knowing that Buffy didn't love him, but cared for him enough to say that she did as he sacrificed himself. He also talks about how he kept trying to play Spike as evil and that Spike was supposed to be a bad boyfriend for Buffy, but too many fans kept cheering for them, so the writers had Spike attempt to rape Buffy, which he hated acting out. (Of course, people STILL wanted Spike and Buffy to get together, so so much for that idea...)
He also says some stuff about Angel, but its a bit spoileriffic, if anything at this stage can be spoileriffic. I think he's just blowing smoke, but I don't recall him spreading mistruths about his character before.
It looked more to me like Paradigm City (and the world?) was a cycle; a play, Metropolis, that plays itself out time and time again, slight variations each time with the same inevitable ending: clean slate.
