The Empire tracks the Lothal Rebels to Seelos. Admiral Konstantine and Agent Kallus arrive at the Seelos System to capture the Jedi. Rex gives the Lothal Rebels a datachip containing old Republic bases in the Outer Rim. Ezra tries to persuade the clones to join the Rebellion, but Rex and the clones instead offer to delay the Empire so the Lothal Rebels can escape. Agent Kallus commands the clones to hand over the Rebels, but when Rex refuses, Kallus arrives with three AT-ATs. Taking advantage of a sandstorm and the Force, Kanan, Ezra and the clones use their AT-TE's main gun to destroy one of the AT-ATs.
Meanwhile, Admiral Konstantine is summoned away by Darth Vader. Instead of meeting him, the admiral meets Fifth Brother, who claims that he will succeed where Kallus and Konstantine have failed. The Lothal Rebels prepare to leave on the Phantom, but Ezra is unwilling to leave Rex and the clones behind. Kanan, Ezra, and Zeb commandeer one of the AT-ATs and turn its weapons on Kallus' AT-AT which Rex destroys with a critical hit. Kallus flees the battle on a speeder. Hera returns to pick up the clones and the Ghost crew. Returning to the Rebel flotilla, the Lothal Rebels and Rex reunite with Ahsoka.
