Can Cass predict what your character is thinking/planning/doing? Joker can be nearly unreadable when he wants to be. He's tricked the Batman after all! But generally, he emotes VERY heavily with body language so she'll be able to see what he's FEELING and could call judgments from there. In physical hand-to-hand combat, I can't imagine why she wouldn't be able to see incoming blows.
If yes, what limitations do you have on this? Obviously, it would be tricky to judge what the Joker is planning in terms of his shenanigans.
Is there anything you'd rather she not be able to predict? Nothing is 100 % ruled out! Just ask about anything you're unsure of.
Anything else? It is SO HOT OUT RIGHT NOW
