It really was what he wanted most of all, actually: to be reunited with the real Fred
Unfortunately that can never be. Fred's soul was completely destroyed.

That had to be the most upsetting part, though. Wesley's definitely one of my favorite characters of the whole Buffyverse, so it's sad to see him go.
Anyway, yes, it was a great finale. And yeah, I'm disappointed that the WB cancelled it. This was the only show I bothered watching on network tv, anymore, and now it's over. Didn't think I'd be, but I'm actually a bit depressed about it. It's given me several years of solid entertainment, and for it to end...

Not to mention that it and shows like it have completely spoiled me. I can't tolerate most of the garbage that passes for entertainment on network tv, anymore. So once Angel's gone, I doubt I'll find a replacement for it.
I honestly believe Spike would live through it all - he's the strongest after Angel, he was the least hurt it seemed, and when Angel signed away his claim to Shanshu, that meant (and the look on his face, he KNEW it) that Spike is the one who is supposed to "live until he dies." Beautiful moment, and beautiful ending.
I agree. He'll probably be the only one to walk out of that alleyway. Poor Gunn. No way he can survive that.

But I've heard that James Marsters is interested in continuing with the character, so that more then anything else leads me to believe that Spike'll survive it. Nevermind that, as you said, Angel signed away the Shanshu Prophecy. Which means that if both Angel and Spike died there, then yet ANOTHER vampire with a soul would have to appear, somewhere. Not likely, so Spike has to live.
Whatever the case, if there're any future shows in the Slayerverse, I'm there. Just hope some of the rumors I've heard pan out. :\
