I also feel like the Rebel fleet scene I’ve been showing you is too… empty? I feel like it would be really upsetting to see that the Rebellion has only like 3 corvettes and Home One left. Perhaps I should take an idea from Rebels and have it be mentioned that the fleet we see in the movie is only one cell of the larger Rebel Alliance. This would also explain why Dodanna and Rieekan aren’t present in the movie- their cells are off doing other things. This also makes the ending of the light-hearted family action movie less depressing.
But isn’t the Battle of Endor supposed to be the big decisive battle? I feel like all Rebel cells should be present. In canon, they were all unified by the time of RO.
