Related: Star Wars Suggests The Bad Batch Didn't Obey Order 66 Ahsoka managed to capture Rex and remove his chip, allowing the two of them to escape from the rest of the clones, but no such details exist in canon for how Gregor and Wolffe managed to learn of their own chips' existence. However, Star Wars: The Clone Wars season 7 revealed that Rex’s statement was not entirely honest, as even after much hesitation he still opened fire on Ahsoka. Although the circumstances of their meeting were never explained in canon, Rex was living with Wolffe and Gregor and revealed to Ezra Bridger that he and his brothers had removed their inhibitor chips, choosing not to betray their Jedi. This lingering plot was left unexplained after being introduced in Star Wars Rebels season 2, when the Spectres, sent by Ahsoka Tano, located Captain Rex on the planet Seelos.

This could very likely lead them to Rex, Wolffe, and Gregor, and reveal whether or not the clones disobeyed Order 66. Previously, it was unclear which characters would be returning from Star Wars: The Clone Wars, but now that it is clear that Clone Force 99 will be on the run from the newly created Empire, it can be assumed that their adventures will cross paths with other former members of the Grand Army of the Republic. The second trailer for Star Wars: The Bad Batch has confirmed that Captain Rex will appear in the show, and his return could finally explain how he was reunited with Commander Wolffe and Captain Gregor prior to Star Wars Rebels.
