An old war comrade of Mal's and Zoe's, Tracey, mails his corpse to them. He also leaves a message asking them to deliver his body to his family. Some men claiming to be with the Alliance are on the trail of the body and catch up to them demanding for it to be turned over to them. The crew can't find anything on Tracey's corpse, but as they prepare to cut it open, Tracey comes back to life. He explains he is smuggling super-organs in his own body. They flee to the planet with the men in hot pursuit and eventually/supposedly agree to give up Tracey. Tracey gets wind of the plan and makes a break for it with Kaylee as a hostage – they shoot him down and Mal reveals they were going to send the officer off since he's out of his jurisdiction and on a personal mission with no authority. Then Tracey dies and they deliver his body for real this time
