Aurora's inner life and thoughts on art are definitely striking! To be honest I think I'd have found them easier to follow in prose, but there is a lot of good, thought-provoking stuff there.

I like your thoughts on adapting The Masqueraders! (perhaps such an adaptation could change Sir Anthony's personality a bit too... :P ) Especially the last one—I can totally see 'hmm, actually I like both these identities in a good balance, let's keep swapping' as a post-canon possibility for Robin in the book (and Letty enjoying it too).
