Well said! I always saw Polly as the exact opposite of Jill. While both a rather adventurous and a wee bit temperamental, Polly seems to be more common sense oriented, while Polly is the rebel.I like Polly because she was gifted both with common sense, and the grace to use it. For example she knew when to try to intervene (tried to stop Digory from striking the bell) and when to NOT intervene (did not enter into Digory and Jadis' discussion in the Garden beyond Narnia)...

I only like the description of Jadis - she is far too evil to be a favorite of mine - imagine killing your sister and an entire army!
