In the 映画 I like Susan better but in the 本 Susan broke my ハート, 心 によって saying the Pevensie's trips to Narnia were only games and fairytales. I also like Lucy because she is so innocent and sweet. But none of them are my お気に入り characters. High King Peter has that right ;)
I like Susan. She's pretty, but Lucy is もっと見る wise. Don't forget that Susan stopped believing in Narnia! :/ But I have to admit that Susie is a pretty cool character. But Lucy saw Aslan even though no one else did.
