I've just got my fingers crossed on the megafic that I may or may not ever actually finish. It spans most of TW to date up through 2x10ish, and I'm not really sure what could happen to completely screw it up - well, I can think of lots of things that COULD happen, but not too many that are likely to happen.

I can manage Ten in small moments, I think, but he's so mercurial and all-over-the-place and so very, VERY easy to get wrong that I'm intimidated by the very thought of trying a longer fic with him. I just don't click with him on a writing level at all. Though it probably wouldn't kill me to challenge myself occasionally.
