It's a rivalry for the ages. Darth Maul and Obi-Wan Kenobi do not get along. From the moment they met when Obi-Wan was still learning the ways of the Jedi, now through to his days of isolation, there probably aren't two people in the Star Wars canon that have quite this level of ongoing hatred for each other.
The rivalry is being renewed on Star Wars Rebels in season 3, as we learned in the new trailer yesterday. But for fans unfamiliar with Star Wars: The Clone Wars, the previous animated series, the return of Darth Maul may have come as an even bigger shock.
We're here to help, with the history of this epic rivalry, and some hints and guesses at what's to come.
