I wonder if it'll end with a timeskip. Zoe gonna win this fight, got in to a coma, and after Lucas and friends win the war against the empire, it'll skip to when Lucas get older and find a way bring Zoe back from the coma.
Moura is definitely gonna betray the empire, I was already pretty sure of it with how he acts when Poppy betrayed Lucas&co, but with that whole "I fight for the winner" I'm sure of it.
Those 2 things aren't connected, even if the series gets massively popular (and hopefully it does) they shouldn't suddenly change their plan and needlessly extend the last arc.
