[Jack nods. Maybe what a SecUnit is doesn't mean much to him, but he knows what it's like to be a danger to people when you don't want to be. He knows what it's like to become something you don't control.]

SecUnit, I do not believe you will lose control in that way. I honestly do not. Especially not from a physical change like this. You are still you no matter what, and I have never seen you be anything other than careful and protective.

[He shrugs a little, and adds,]

I don't know if that will help you, but that is what I believe. One more measurement, please, along this line. Then I should have all that I need.

[He touches the bridge of his nose, and traces a finger down to his chin.]
