Yeah the issue is we don’t have any real footage to work with, and if things are only going to be implied then they shouldn’t really be pushed to the forefront. I think Jannah’s line “you started something” already implies there could be other defectors besides her group, it could even be a factor in the FO’s struggle to maintain control, but I don’t think this should be pushed as a major plot point in the movie since we can’t give it the proper payoff it would need.
And then I assume this message also goes out to the other Final Order ships (since it reaches all the First Order ships across the galaxy), which means the whole civilian fleet would also be shooting down ships full of these newly unbrainwashed troopers, killing them all without a second thought.
Nah, Sith troopers are a different breed entirely. They’ve basically been raised in a religious cult and have only seen the grey skies of Exegol. Whereas FO stormtroopers have seen countless worlds and scenarios that could help them shake off their conditioning.
The movie doesn’t actually explain anything about the random red troopers so this doesn’t really help, also in the First Order briefing where the lady says “we need to increase recruitments”, they’re all talking about the new fleet so I assume she means they need more troops to command this new fleet.
