[Law is a punk and this is an immutable truth that no amount of trauma or maturity can cure him of. He follows after Corazon, not going to argue but definitely keeping an eye out in case he ends up being all talk after all.

He'd been given them thanks to Corazon's sacrifice, so he'd put his full effort into mastering them and using them to their full advantage. So he'll flash one of his cocky grins, before generating the small beginnings of a Room in his hand before expanding it outwards.]
