Buffy
You mean he wasn't his sick, twisted alter-ego before you fell in love with him? I'm not really sure how vampires in your world work.
She was younger from the timeline you're from, huh? Dawn has been here for a real long time with very few people from home to consistently rely on. She had to grow up. Maybe too fast, even, for someone her age. And while she might have her own place and a car to get her by, I still think she needs someone in her life to comfort her and talk to her and support her in all the ways that family does for one another. I think she might have been lonely, before you showed up.
I probably shouldn't. With the blood, I mean. It's tempting. Dear god, you don't know how tempting it is. But if I drink your blood, I'm just gonna want more. It's dangerous.
But if circumstances change and maybe one day I do need blood from somewhere, I'll keep you in mind. Thanks for offering, anyway. And I seriously hope I didn't weird you out too much, telling you all that demon blood stuff about me. Some people don't take that sort of thing very well.
