Hmmm - my first thought was "Ah, that's my Love's Lost Series opener (Loves Lost), but the rest of it after Spike helping her out is not, so I don't know what to tell you. Could you have confused two fics? Buffy captured, raped and tortured and video taped for Giles is spot on. And Spike does help her out, in terms of making her stronger so she can fight back. However, Giles rescues her and provides her with the opportunity to get a bit of her own back. It's the first (and definitely the darkest) in a steadily Spuffier series of fics that get lighter and fluffier as the time passes. |
