Here's a thought for you guys....
Hudson, right.... Hudson didn't die on screen. They don't kill you, remember, they take you alive.
So the aliens took Hudson from operations, a new host: then they dropped him because they were sick of his winging. Left alone and without a way off the rock, he ran from the colony and survived the processor reaching critical mass.
Fresh as a daisy, ready for a new film.
Hudson Lives.
I got ninja'd!
