In The Rise of Skywalker, the protaganists track the assassin/bounty hunter Ochi of Bestoon to a planet where they get sucked undergound and find
his decomposed remains.
My initial assumption was that he was unable to find a way out of the tunnels and died there, and the plot would center around the heroes trying to find a way out. But in the following scences they
walk out of the tunnels with no fanfare or explanation as to how they did so.
Are we supposed to assume that he
was killed by by the giant worm thing? The inference was it only attacked because it was wounded and it slinked away after Rey healed it.
So what actually killed this person?
