 CREW: Shortly after Serenity arrives at the Eavesdown Docks, Wash  drives the mule down the ramp, stops at the bottom, has a few words  with Zoe, then drive off. You can see a crew member push the mule  down the ramp and jump away from the camera (too late), and then  when he drives off you can again see a crew members hand grab onto  the front bumper of the mule to pull it out of the shot.
