the mule and the skiff are booking through the rocky terrain. the skiff swings closer, but jayne peppers it with automatic fire and it swings away. there is sporadic return fire.
zoe gets the mule in front but a harpoon thwinngs through the air from the skiff and s} nk! goes through jayne's leg.  the harpoon grips the leg and pulls -- jayne goes flying off the back of the mule, mal just grabbing him as the harpoon line reels slowly tighter --
the mule reaches the flats, away from the rocks.
serenity tries to get altitude -- but slams right into the oncoming skiff, tearing it apart --
