Ok, I've had a quick read and done my best with it, although I'm having a bad day with my concentration, so I can't guarantee my comments will be all that constructive.

I don't read much fanfic, just because the concept generally doesn't appeal to me, but as much as I know about it, this seems pretty good for the fic genre. I particularly like the way you have merged two of your fandoms in this way. :) It was readable and dramatic with a great twist at the end and it made me giggle in lots of places.

One thing I would say is that I had trouble picturing the scenes in my head (possibly to do with my poor-concentration and therefore lack of engagement, though), but perhaps a little more description of the settings, etc. might not go amiss? It's a difficult balance to get right though, I know. Also, it's best not to repeat words/phrases within a short space of time if you can possibly avoid it (I'm thinking specifically of where in the penultimate section you used, "for the sake of decency" in rapid succession) - unless of course the repetition is there specifically for emphasis.

Hope that's helpful. On the whole you seem to be rather good at this fic thing. ;)

I would suggest showing this to Rose too, as she knows much more about writing creatively than I do.
