Can Cass predict what your character is thinking/planning/doing? Probably...not.
If yes, what limitations do you have on this? Aslan is probably one of the most and least predictable beings in the city. So, uh...case-by-case basis maybe?
Is there anything you'd rather she not be able to predict? We'll talk if it comes up.
Anything else? Er...Cass should meet Jesus Lion? One day?
