I’ve been very intrigued and impressed with what they’ve done with Maul. Back when they first brought him back I was with everyone else rolling their eyes but with every appearance he’s made they’ve continued to grow and evolve the character. Originally he was supposed to be killed off in TCW but that whole plan went out the window when the show was suddenly cancelled without warning. So he became this massive loose thread that made it inevitable he would be dealt with in Rebels.
Also, it was very obvious who they were talking about in this latest episode. They just about slapped you over the head with it. This again was inevitable, ever since Maul first returned he’s been obsessed with that character and they never got their proper rematch in TCW. This also effectively signs the death warrant for Maul as he can’t know about that character and continue to live. So there’ll be no face off with Vader now. That battle would be all fan service instead of serving the character himself and where his path has been leading this whole time.
