Heh, yes, I can see that perspective. :) A rec that details a story so that it barely needs reading isn't much good, is it? I hope you'll allow me to explain why I specifically chose to highlight that aspect, though.

In four years of reccing, I've learned to look for the "hook" to coax the reader into clicking on the link to read the fic. From what I've seen of Narnia fandom on LJ/DW (that's probably only a small part of it, of course), a lot of people out there very much like the idea of stories that acknowledge Susan's fate without blaming her or seeing her as being in need of "redemption" just because, y'know, she grows up. So saying that it's Susan, and that she's snaked, is the hook for me to tempt readers to read the ficlet and find out what happens next.

What the Goa'uld chooses to do and the reasoning behind it? That's the horrifying creepy superb twist of your fic.

...For me, anyway. :)

If it truly bothers you, I'll edit the rec. Let me know.
