I jussst wanted to say.... please consider how young is Elizabeth :( i know is not an easy to love character (even i hated her for a lot of years..) but she's a child, literally. And her role was to be the only thing still childish and pure around (Our-)Ciel... she had been constantly force to get involved in this dark mess and now she's not what she was supposed to be nor what she wanted to be for "Ciel" ... yup, you're probably still thinking that she's childish, and immature, and you're right! But she's actually more complex than that.
