A human that has a kinky obsession with women.  My first guess would be Warren (if it is a character from the actual show).  I could see his character enjoying controlling young vamp females.
Spike has a bit of his original edge back (feeding and not willing to stop). I like it.  Buffy did trust him without his soul in the beginning,  I hope the fact that he is feeding doesn't stop that.

Poor Spike, it's lucky he's got no expectations. Sooo it's a human behind everything. I wonder if he's woked out the formula for the drug used in the cruciamentum. Although that wouldn't explain how he can weaken Vampires too. Seems both Spike and Buffy are at risk. Good reason for working together. Super update.  

Hee - not sick sick - just sick in the head  :P

AhHa!!  We have a "new" villain.  Is it Ethan Rayne or some leftover from WR&H?  Is this why Spike is not healing faster?  BTW, he never needed a soul anyway (IMNSHO).

Thanks again for your fab talent and sharing with us.

Talk about going back in time and connecting with the future - how many times did Buffy tell him that their relationship meant nothing to her, that he was little more than a sex toy that needed to be hidden.  How many times did she imprint his heart and mind with "your an evil souless thing." 

Even with all the great things that Buffy brought into his life some words have such power to hurt that they always remain, like ghost ready to haunt.   What a tragic and also heroic love these two have shared.

Your idea of Slayers losing their powers is interesting - especially with theme in the comic book timeline of powers lost and lives completely changed.

A great way to celebrate James Marsters birthday this August 20.

His soul is gone?? I don't care one way or another, but I feel bad for him because he went through so much pain and suffering to get it for Buffy. And Buffy who won't let herself love him without it. She probably won't even think about the situation the girls are in in comparision to what is going on with Spike. Here is a souled up human killing people getting them turned and trying to kill off the slayers. Plus he seems to be targeting young girls. Spike is feeding and rarely killing and from the sounds of it only feeding off bad evil people but still fighting demons. That makes him better than the guy trying to kill her. But Buffy won't see it that way. Humans are still good no matter what they do and an unsouled Spike is evil no matter what he does.

Of course Spike didn't want her to know he was back. He knows without the soul once she found out about it she would probably stake him. He never thought she loved him so what would stop her from trying to kill him? He probably just wanted some time to come to terms with it all and move on silently with no one the wiser.

The human makes me think of a crazy shanshued Angel/Twillight.

Disturbing turn of events.   

Well, that explains Spike's attitude - and of course Buffy reacted just the way he expected. Can't wait to find out about the creepy human guy...

His soul’s gone, Will. Gone and destroyed with the amulet. - Boy if only somebody had a really good friend who's majorly into magic who could fix this up. 

Please kill more slayerettes.  I really like that part.  Also, I'm sick.
