He might not know all that much of the world, but these things add up to something that makes his throat tighten and his fist clench in fury. But his voice is as calm as he can make it. "'course I'll help you get back to them, and I won't hurt you. No needles, no cutting, no tests." Certain, and honest, and final. No damage to him from her.

"But if you want it, I have some juice. Don't have much water, sorry, but there's juice. I can leave it here an' back off, so you know I'm not comin' closer."

He's a human. His presence alone isn't likely to be comforting, so he has to figure something else out to calm her down.
