why does it surprise you you got Book?

You're not crazed like River.
You're not snotty like Simon.
You're not ice-over-passion like Zoe.
You're not sarcasm-over-sweet like Wash.
You're not bastard-over-decent guy like Mal.
You're not crazy bastard over more crazy bastard like Jayne.
You're not all innocent except for the sex like Kaylee.
You're not all sexy with diplomatic on top like Inara.

But you are all wise in a very subdued badass sort of way.
