Spike falls for the first slayer he met, they are together until her watcher finds out and tried to kill her. Spike turns her but it goes bad and he ends up killing her, then all the watcher people/family? Around in revenge. Dreams of her and ends up with a stone/gem that helps him/keeps him safe? Not the gem of amara. Helps Buffy. At one point has to remove the gem that he had hidden under his skin on his leg. Buffy/spike love. That's all I remember, please let me know if anyone remembers it. I believe I read it on fanfiction.net. Can't seem to find it. Thanks! |
