The plot was inspired by H.G. Wells' 1901 story "The New Accelerator", about a scientist who develops a drug enabling him to move so fast that no-one can see him. From his viewpoint, everyone else seems frozen in time.
At the scene in the Skate/Paint-ball shop Meeker is carrying two paint-ball guns. As he is walking you hear the paint-ball gun shoots twice. First the nozzle has a protection plug and second there is no tank attacked, so the gun could not make that sound.
