Jack is behaving himself. He stops just out of arm's reach, though he does look like he's vibrating a little with keeping his desire to touch in check, tails flicking this way and that. Still, he's smiling, and obviously relieved. "I was afraid you'd come out of that husk shell not being yourself anymore. But here you are!"

He understands the frustration and fear of not knowing something, something big like that, but he's also just so glad that people can go into those metal things and come back out just fine.
