Caesar sighs a bit in relief when he doesn't get slashed for his efforts. He lets his shoulders relax a bit. Okay, Zak is letting him work.

Good thing he's scanning himself first, regardless. Caesar quietly does the same sweeping motion he did with Zak, turning it on with a little beep about at his chest area and then moving it downwards. Then back up and down once more. Caesar smiles a bit as the scan is complete and some information is shown on the screen.

He turns the brightness down after a moment of thought and turns the screen to show Zaknafein. "See? That's it. Now your turn, Zak?"

A question, asking permission with his voice even if the other man does not understand his words. Look, he's not dangerous, okay? Caesar even thinks he can show the elf how to hold it, just to be sure.
