Message:The three NPCs will never leave the levels of the ship they inhabit. They can see and react, interact with their counterparts. They will just say that's my brother; he's an idiot. What is not determined yet is how they react if, say, Capt Al is told that Nate is no longer on-board. Man overboard!?!
Killing one or more people will not get the players out of this loop. Killing may help you get there but there is no direct escape point that requires murder. Other NPCs (not crew) will also oppose the players. Whether they are defeated or eliminated is a matter of taste.
Hint, look for a sequence of events. A good first step was determining the order of the planets to even allow escape. That you have done, but it's the most dangerous path. Aren't they all?
There's a bit of Inattentional Blindness happening. The gorilla is walking right across the court, but you guys are still counting bounce passes. (The obsession to be +5 GUN makes me smile.)
