I believe that Lindbergh, one of the Commanders of the Revolutionary Army, may have betrayed the Revolutionaries at the Reverie.
This theory operates off of the assumption that Lindbergh is based on Charles Lindbergh, an American WWII-era pilot.
- Lindbergh is an inventor / Charles Lindbergh was an inventor
- Lindbergh wears aviator goggles and flies with a jetpack / Charles Lindbergh was a pilot
- Lindbergh is a high ranking member of the Revolutionary Army / Charles Lindbergh was a high ranking member of the US Airforce
- Lindbergh seemed hesitant to attack at the Reverie / Charles Lindbergh didn’t want the US to challenge Germany
- Obviously, their names are very similar
Despite serving in the US Military in WWII, Charles Lindbergh was a known Nazi sympathizer. He believed that preserving European blood was more important than democracy, and was very much against the idea of the US and UK joining WWII. He was often praised in Germany and even received a medal from Hitler.
His actions and words led to him being considered a traitor by President Roosevelt.
So I believe that the failure of the Revolutionaries at the Reverie was at least partially caused by a betrayal by Lindbergh.
