Ooooh, your fic sounds awesome, because I love multifandom mash-ups and also snarker boys.

I initially had problem understanding how I can hate Xander and also wildly love Ron (Ron may well be my favourite HP character). I mean, their role is similar (layabout snarky loyal prime sidekick) but the effect they have on me is wildly different. What's the point that divides them? Xander's Buffycrush? Gender dynamics? The fact that we never saw Ron grow older? (I, too, didn't precisely dislike Xander until later seasons.)
