While Rex has found his old friend, Echo, alive on Skako Minor, the Republic heroes find themselves pinned by Wat Tambor’s forces!

Though it took some time, Tech finally disconnects Echo from the Techno Union mainframe. “Rex...I got a big headache,” the clone says with a laugh. As Tambor’s decimator droid closes in, the clones and Anakin look to escape through an air vent in the ceiling.

The last to depart, Wrecker leaves a gift for the Separatists. “I’m putting an end to Tambor’s little science experiment,” he says, tossing detonators onto the system controls. Anakin lifts Wrecker into the vent, and the console goes up in a fiery explosion.

Echo leads the group to the only way out -- a narrow pipe connecting two buildings, with a landing platform on the other side. Below them is a giant nothingness.

But the heroes don’t get far, as Tambor’s security droids surround them. Running out of options, Tech has an idea.

He had recorded the distress call of the native Poletec’s flying creatures, the keeradaks. The clever clone plays the sound, and soon a swarm of the beasts appear. The heroes jump onto their backs and make their escape!

The clones and Anakin return to the Poletec village. When a pursuing droid attacks, the Poletec chief becomes angry, claiming that the Republic brought the war to his world.

Rex agrees, but presents the mechanized Echo as proof that the Techno Union is not neutral. They chose sides, he says, and so must the Poletecs. Meanwhile, Tambor sends reinforcements to recover his “experiment.”

The Separatist droids soon arrive -- and both the Republic and Poletec forces meet them head on! The fighting is intense, but the clones, Anakin, and native soldiers stand their ground.

The battle is far from over, however, as gigantic octuptarra droids appear! Anakin and the clones take them out one by one, sending the towering droids toppling onto the dusty ground. The remaining droids retreat to the Techno Union stronghold.

This defeat angers Tambor. “We must find a way to recoup on our investment,” he says. Meanwhile, the Poletec chief bids farewell to the Jedi, and the Republic heroes begin to board their ship.

But Echo stops his captain for a moment. “Rex, thanks for coming after me,” he says. “That’s what brothers do,” Rex replies. “Hopefully, it’s going to be just like old times.”

The Techno Union made several special modifications to Echo, including a scomp link. Attached to his arm, Echo uses the device to unlock the vent.

The decimator is a devastating piece of new Techno Union technology first appearing in this episode.

The gliding D-wing droids are a unique variant of the classic battle droid used by the Techno Union.

A new flying variant of the octuptarra droids makes its debut in this episode. The standard version first appeared in Star Wars: Revenge of the Sith.

Wrecker's fear of heights, established in the first episode of the season, comes into play when the clones must cross a chasm on a narrow pipe.

As told to StarWars.com, voice actor Dee Bradley Baker assigns each clone an adjective to make their personality and voice distinct in his mind. His adjective for Rex: "solid."

Skywalker Sound's Matthew Wood, voice of Wat Tambor in the original run of Star Wars: The Clone Wars, returned to the role for the final season on Disney+. But that's not his only performance in this episode...

Wood also voices the droids of the Separatists, including the new D-wing security droids.

"I feel very connected to these individual clones and the hardship that they go through, and what they feel, and what they slowly come to realize. The depth of the tragedy and the difficulty of all of these different forces that they're working with and working under, sometimes that they don't even realize until it's too late." - Dee Bradley Baker ("Rex" and all clones)

"There's no preparation for me, other than just, I can see it in my mind. I can see who these guys are and I can see how I think they're going to move and their proximity to each other." - Dee Bradley Baker ("Rex" and all clones)

"I was also terrified that [playing the Bad Batch] wasn't going to work...fortunately, the writing is so good that it makes it a lot easier to do this. The coloring of each character is distinct enough to make an interesting dynamic as a team. They all have a different tone and setting and heat and level of reactivity to add to the particular usefulness or skill that is their superpower, so to speak." - Dee Bradley Baker ("Rex" and all clones)

"It's better than it's ever been, The Clone Wars." - Dee Bradley Baker ("Rex" and all clones)
