Right. Kinetic force does in a pinch, but I wouldn't want to use it that way, either.

[His gravity manipulation has similar principles - he could probably deflect stuff with it if he really tried, but why would he? He'd be even worse as trying to hold down a fort, he needs to be mobile, and he has other stuff to be doing, anyway.]

I could send stragglers back to a meeting point if I came across them, tho.
