The final arc of Star Wars: The Clone Wars takes place concurrently with the events of Star Wars: Episode III - Revenge of the Sith, and one fan has made a video touching on that connection.
YouTube user John Jay has made a video syncing Ahsoka Tano and Darth Maul's lightsaber duel in The Clone Wars episode "The Phantom Apprentice," with that of Darth Sidious dueling Mace Windu and other Jedi in Revenge of The Sith.
In "The Phantom Apprentice," Maul and Ahsoka duel in the throne room of Mandalore, where he confessed that he intended to lure Anakin Skywalker and kill him in order to disrupt his former master's plan. Ahsoka finally defeated Maul and let her clones capture him, while he raged on about the fall of the Republic. Simultaneously, Anakin stopped Windu from killing Palpatine, cementing his fall to the Dark Side and his rebirth as Darth Vader.
This video perfectly syncs together both moments and balances the triumph of Ahsoka's victory with the fall of her former master. Given that the next episode of The Clone Wars deals with the fallout of Order 66, it's only fitting that the beloved series ends on a bittersweet note.
Streaming on Disney+, the final season of Star Wars: The Clone Wars stars Matt Lanter as Anakin Skywalker, Ashley Eckstein as Ahsoka Tano, Dee Bradley Baker as Captain Rex and the clone troopers, James Arnold Taylor as Obi-Wan Kenobi, Katee Sackhoff as Bo-Katan and Sam Witwer as Maul.
