1. Tens of thousands of Death Stars
At the conclusion of Return of the Jedi, it’s revealed that Emperor Palpatine’s enormous armada of Star Destroyers concealed Death Star weaponry. When one of them destroys a planet for no apparent cause, it’s revealed.
The Resistance members then converse and come to the conclusion that, since all of those ships can do it, they must be capable of working together. This appears to be an illogical conclusion to reach because it implies that the villains have a whole armada of Death Stars, which would unquestionably make the most ludicrous event in any “Star Wars”
The novelization, in case you’re curious, puts the number of ships in this fleet at “tens of thousands.”
