So in the last few weeks I’ve been watching the Clone Wars series somewhat out of order. I’ve pretty much just watched the “essential” episodes (Mortis, Maul, Ashoka’s trial, etc.), and I’m currently just watching the rest in whatever order I feel like at the moment.
Is it possible to do this with Rebels?
No. Rebels is structured linearly and as such for a first time viewing should be watched in order and in full.
