The shift is noticeable, clear, and yet it is not gaining an inch from the man staring at Jesper with ice hollow and cold and unyielding. Another time and place and had Jesper tried this Kaz might well have found himself tongue tied. Tongue tied and maybe even curious.

All of that is burned out of him though. Covered in the stench of rot and as spoilt as fruit left out in the sun.

He moves very slowly, very deliberately, closing his fingers around Jesper's wrist in a tight grip. Not jerking his hand away, just pressing his thumb into the tendon between the bones.

"Whatever has gotten to you? None of is will benefit you with a broken wrist, Jesper, so do not try that again."

Yet he doesn't break his wrist as he would have with someone else without a word. Just a sharp rap of the crow's head and been done with it. He can't help the anger within him though. Both at the feeble attempt that only made his cheeks flare red and hurt in ways he is not used to coping with and from the rot that eats away at his soul.

"What I want is for you to accompanying me back to the boarding house. Do not make me have to find a way to lug your unconscious body there. Do not make me hunt you down. You know what I'm capable of, Jesper. Do not make me unleash it on you."

Because he wants to unleash it all on someone. He wants to show this place just what Dirtyhands is capable of. Not with Jesper though. Not if he can avoid it.
