Oh, my. Mal is in for quite the surprise...

What a tease! Very good one-shot, but still leaves the reader with many questions and wanting a follow-up. >_<

You've brought up something that I've considered before myself; using the example of Wolverine, his mutant healing factor allowed him to live essentially indefinitely, as it counteracted the effects of aging.

Why wouldn't a Slayer's body/healing ability do the same? While it can heal wounds at a much higher rate than a human, and certainly slower than Wolverine's, the effects of aging are much slower and much more assiduous. So, why COULDN'T a Slayer live much longer, or even long enough to be around after the human diaspora? Good concept.

Very interesting. Dawn would always be Buffy's first child. To any mother that one is always just a little more special.

Yes. In this 'verse, Mal's the first one she's let get anywhere near that important to her in all the five hundred years since Dawn.
