For the double split and wave particle duality, I would see the 8-particle as a Bee that zoom's through the Aether, the waves that it makes affects it's path when they are redirected through the second split. This would mean that the parts of the waves travel relatively faster than the light particle, but the speed of the vibration is gradual it precedes, goes along and tails the movement of the particle just like it is for every movement of an object through a medium.
It is a different level of passage of energy, just like a tower build up out of blocks that vibrates when a block at a lower level is pulled out, it surrounds the motion of that piece, the wave and the particle are complementary.
