Rue! ^-^ Although Prim seems really sweet in the books, Rue just... touched me, I guess.
Also, I don't like saying this, but because I watched the movie before I started the trilogy, the first image I got of Prim wasn't as sweet, kind and beautiful as in the book. <3 Unfortunately, your first "impression" is the most memorable, and whenever I think of Prim, I know think of Prim.. in the movie. (Not that she's bad or anything, but ...do you know what I mean?)
I still like Prim, though. smile
But Rue is just so awesome 4laugh
