Another blank stare tells you that it can't.
Tippy lets out a jawless laugh, something that sounds more like a horrible coughing than someone who was tickled by something funny.
She opens up a small side panel built into her jaw and changes out a small vial of liquid and inserts a new one. She lines it back up with her mouth and the joints pop into place. She bolts the jaw back in and rotates it. An audible click and the sound of a small servo comes from her mouth as she exercises the opening and closing action of her jaw. The mechanical jaw looked like something out of a movie where robots took over humanity. It certainly wasn't an augmetic like some of the fancy Kintharians strut around, it was crudely made from the looks of it with a military stamp etched into its metal exterior. In either case, the winces she made made it clear that its painful to wear.
She turns again to the robot and gives a metal smile.
"I've heard all kinds of awesome things about Helian robots knowing other languages but i'm amused ASL wasn't one of them. Its a shame that that's happened to you. War sucks it really does...
