Can Cass predict what your character is thinking/planning/doing? Kinda. If Starscream is in car mode, she'll only have his voice to work with, which isn't so bad since it's quite expressive. If he's in robot mode...hell yes.
If yes, what limitations do you have on this?None that I can think of
Is there anything you'd rather she not be able to predict?Same as above
Anything else?Have fun!
