I hadn't watched Rebels.
I thought I tuned into the second episode by mistake because it felt like I had missed a bunch of introductions. Pretty lost. Watched the first episode of Rebels afterwards and more made sense.
I don't generally like cartoons (of any type), but I guess that's just part of the backstory now. I made it to season 6 of Clone wars, but it was honestly a slog. I'll take another run at it.
I know it's only two episodes in, so will give it time. Was sorry to learn about the passing of Rey Stevenson.
