With the latest preview clip of Darth Mauls return in Star Wars Rebels Twilight of the Apprentice we have now learned more about Mauls motivations and his desire for revenge. WIll he use Ezra and the other Rebels members to help further his potential goals of gaining vengeance against Darth Sidious for his manipulation of Maul and his involvement with the deaths of Mauls brother Savage Opress and his mother Mother Talzin. How will the crew of Rebels deal with Maul , specifically Kanan. I think the question of Who is the Old Master has been answered.
