Can you heal someone who has been killed? 
I’m thinking of a standard  

 crewmember who has just received 3  

 wounds, causing them to be killed/discarded. If the crewperson had a  

 Panacea Autojector attached, could they  

 – jettison to remove 2  

 wounds to bring themselves back to life? 
Or using the Last In First Out (LIFO) principle is it more accurate to say that the  

 Reaction removes 2  

 wounds from the attack and thus they were never killed? 
Seems a trifling difference but I can foresee heated debates arising at the game table (at least with some of the 
lawyers gamers I know).  
 
Then again, maybe they really are dead...
