Her "sense" was my logic when I went downstairs to pick up another book to read over. It has nothing to do with me trying to help pick up the slack now that Fred's gone; even though I do make an effort not to mention science related things around Wesley. I don't want to do more damage, especially with our Fred version of Violet Beauregarde running around. She's a perfect reminder of everything that Fred wasn't. Cold, empty, confused--Illyria is nothing like the warm, intelligent little sister who was determined to keep fighting.
I wish I could find a way to hate her for it.
I'd never tell Wesley my opinion on this, but I think Illyria is just as much a victim as the rest of us are. She's trapped, and probably scared. On top of being scared, I doubt that she understands anything about fear.
I think I pity her, and I hope to God that Fred wouldn't mind.
