I understand not putting a Rebels character in RO, that just makes sense, but why not the other way around? Would be an opportunity sorely missed. Isn’t this what the story group is for?
They did put a Clone Wars character in RO though, so maybe. On a side note, I’d love to see how people react if Maul is in an upcoming movie. I’d bet that 90% of people think Maul is still dead.
