Claudia Black won’t be in Ahsoka Season 2…
“Well, I’m going to be transparent. They picked up season two, picked me up with it, and then Disney, which is structuring things differently these days, could not pay me what I needed to be paid as a single mother to keep all my responsibilities going at home in Los Angeles, because they were filming in London. It was not something that they could make happen, and therefore, I had to bow out for season two.”
