Yep--I think he even said something to that effect when he met Mohinder. I think it's actually also rather close to Rogue's power, because he definitely touched Isaac when he went to help with Isaac's OD-ing. And he touched Nathan when the latter flew up to grab him, of course.

Future!Hiro does present a little bit of a problem there, but maybe Hiro becomes more and more able to control time stoppage for others, too?
