I feel like I already have too many details. The kind that make me sick. And then, you know - the punching. Basically Angelus sired her, then they came back and killed me, and had lots of kinky sex pretty much the entire time.
See, don't you wish you didn't have the details? Okay, maybe it's not as bad for you because it's not you they killed or your ex she's talking about... Bleh.
I don't know much about the Wesley/Faith/Angelus drama of when I guess this siring happened. I know that Angel had gone bad...Willow went out to help at some point. Fred would probably know better than anyone.
