Using super speed to get in and out of places was pretty damn useful... using it to walk through walls? That was a whole new ball game.
Tommy cocked his head and considered what Bart had said. Instead of directing speed outwards, you turned it inwards. That made sense. Tommy had done that... once. Kind of. Before he had freaked.
"How do you not, y'know," Tommy brought his hands together then spread them outwards, "boom?" Because while blowing yourself up might have been impressive, Tommy was sure that'd be a one time deal.
