Umm, what?
The First has always been, will always be.
Yep I know. Thanks for pointing it out. It doesn't really contradict anything I said though, does it? Unless you misunderstood what I meant about him taking a renewed interest in Buffy and the gang. Which it clearly DOES 3 episodes later and onwards.
Why couldn't Willow raise a dead person from the grave?
I never said she couldn't. Saying such a thing would be silly considering she did it at the start of season 6, arguably setting her on a course leading her to the very situation we are discussing now. One would think that would occur to someone before asking such a question.
My point was that if she actually raised Katrina, she wouldn't just casually stroll into shot, chatting away to Warren. She'd be dirty, and traumatised, and unless she had some kind of magic teleportation ability, she'd have to make it from wherever she was burried to where Willow and Warren were.
Why couldn't Katrina be a Ghost? Why wouldn't it make sense?
Taken from Buffy wikia
A ghost can only be visible to the human eye with ectoplasm. When Spike was rendered incorporeal following the Battle at the Hellmouth, Fred's scans indicate that Spike is technically not a ghost: he lacked ectoplasm, which would make him invisible to human eyes
Further to this, I doubt a "ghost" could just be called forth, even by someone as powerful as Willow. If you are to think of a ghost as the spirit of someone who had died, it has already been established in the Buffyverse that when a person dies their spirit moves onto another dimension, eg Buffy going to a happy dimension ("Heaven") or for another example Angel going to a hell dimension. So we can assume that Katrina's spirit has equally moved onto another place. Does Willow really have the power to call someone's spirit forth from another dimension, especially considering she doesn't actually know who it is that she is calling in the first place?
Thanks for your thoughtful reply, hope I made it more clear to you where my thought process was coming from.
I always thought it was just some illusion that Willow made!
Me too! I'd never really given it much more thought but then as I pointed out above, how could she make an illusion of Katrina if she doesn't KNOW it is Katrina that he has killed. She casts the REVEAL spell in order to find out if and who Warren has killed before.
So the spell then reveals Katrina to Willow (and Warren), but using what form? From the logic I explained above (for those who needed it spelled out to them) it couldn't be a ghost and it's unlikely she actually raised Katrina herself...
The First Evil (who has been around forever, yes gold star to ILLYRIAN
🙄 ) is suddenly taking a renewed interest in the Slayer and the slayer line, as explained further in season seven this starts when Buffy is raised in season 6. So it is believable to me that he could actually "step in" at this point as Katrina - it makes sense especially considering that it helps Willow on her path of destruction, something the First Evil
wants Willow to do.
To be honest, I just thought it was a neat little theory and I didn't think there was a lot of substance to it. I just thought it was something cool to think about and speculate over, even if it probably wasn't the case. But in having to explain it all out I have actually realised that it makes so much sense.
