Definitely not wonderment. It's been several years since I read it (Before the muses even made wonderment lol).
I know it 100% was based out of sunnydale. And I wish I remembered more about it. But like I said it's been several years. I believe it was finished. I wish I could remember more than just Spuffy, claiming, baby fic. The powers that be brought back Joyce and Anne and Buffy had some serious Wiggins on not thinking she could be a mom. Plus Angel kept showing up at her window spewing spike is evil stuff. And I remember a scene where spike was drinking breast milk from the tap and Angel witnesses it.
The second one did start pre-series. I know for a fact it was on EF when I read it (I can't find it under my past commenents, favorites, bookmark or read stories) it was finished. Started shortly after spike was sired. He found and fell in love with the current slayer who looked exactly like Buffy. He didn't kill any humans except one (wanna day it was Jack the Ripper or someone to the same evilness) the slayer found out and before they could talk it out she was killed by Angelus in front of Spike. Fast forward to season 2 and spike sees Buffy. He breaks up with dru and goes for Buffy since she looks and acts like his lost slayer. He kills Snyder to help her life be easier. the scoobies research if slayers are reincarnated. Finally Giles goes to eathan to get help "keeping Buffy away from Angel" so instead of the princess gown she dresses like spikes slayer gaining all of her memories. (I don't remember how or why but they end up at Cordy's house for a party). Buffy makes with the big inner feelings and realizes she wants to be with spike. They make with the lovings in like the last chapter. It wasn't a big bad type story but very angsty story.
