After paying close attention to Lindbergh (The Steampunk Cat Mink) from the revolutionaries and the space pirates
you can see some similarities. The space pirates are all based on animals whether they are minks or cyborgs that are aged.
Now there's a video on youtube about How LIndbergh Betrayed the Revolutionaries, which has yet to happen, but the video gives a well thought out explanation on who the character LIndbergh might be and can become. At the moment he is allied with the Revolutionaries, but there is potential of Lindbergh being a spy for the world govt or even Germa since the character is based off a Nazi. Maybe this could explain Sabo's plan at the Reverie failing?
Anyways whether or not LIndbergh's actual position is clear. We shouldn't doubt that he has any relationship with the space pirates
Could this mean that the Revolutionaries have some involvement on the moon? Or Could it be the World Govt?
You can take this any direction, but the fact that after seeing the similarities there's no doubt that they aren't related.
