Also, Mace mentions that the Republic has nearly a dozen active battlefronts on the planet -- which reminded me that he isn't a playable character in. Developer Dice should really get him in there. Anyway, here come the spoilers.
The fortune cookie
"Trust placed in another is trust earned." This pearl of wisdom refers to the Bad Batch's initial lack of trust in Echo -- they reckon he became a Separtist agent during his time as a Techno Union captive. They learn to trust him and win the day, and he joins them. I wonder what these guys will do when Order 66 goes down?
Echo's new look
The clone trooper was turned into a cyborg during his captivity, so his physicality is quite different to his brothers now. As such, he wears less bulky armor and has a unique helmet design. It's super cool, and reminds me of the armor Samus Aran wears in Metroid Fusion -- that was like a sleeker version of her traditional Varia Suit.
He ultimately uses his new body's hacking abilities to defeat the Separatist droid army by gathering them together and sending a feedback pulse that shuts them all down.
Executive producer Dave Filoni noted that the changes Echo's been through push him to join the Bad Batch.
"Echo joins them because Echo's now a weirdo -- is there a nicer way to put it?" he said in an official behind-the-scenes interview. "He's half-droid, half-clone. What an enigma in the Clone War."
The incredible Mace Windu
Mace Windu and Obi-Wan leap into a hangar full of Battle Droids, and Mace gives them a chance to surrender. It doesn't work, but proves that he's an absolute badass. Since Lucasfilm knows what it's doing, it released a clip of this moment so we can revel in it easily.
When Trench starts a countdown on a bomb in the fusion reactor on Anaxes (it looks a lot like the one in the second Death Star in Return of the Jedi), Mace runs off to deal with it on his own.
A taste of Vader
The Jedi Master gets a little help from Anakin, who confronts Trench on the dreadnought. The admiral reveals just how much he's leaning into a creepy spider-person thing by firing web-like net at Anakin, but the Jedi dodges it.
Then Anakin gets a bit dark side as he mercilessly slices off Trench's cyborg arms to get the last part of the code Mace needs to deactivate the bomb. When Trench tries one last attack, Anakin ends him with a lightsaber through the chest.
"Admiral, it was a pleasure," he says lightly as Trench falls to the floor with a smoking hole in his torso and gives us one last "tic-tic-tic."
He also lies on his back with his limbs curled in, much like a real-world spider, as noted in the official trivia guide for this episode. I'm no arachnid doctor, but Trench probably isn't OK. You'll be missed, creepy spider-dude.
Bad Batchers Crosshair and Wrecker have a competition to kill the most droids, with Crossfire employing an absolutely incredible ricocheting shot to come out on top. Things turn out okay for Wrecker though -- Anakin gives him the honor of blowing up Trench's whole fleet as they depart.
"This is the happiest day of my life," says the towering clone, before hitting the button and setting off the fireworks.
No Wat Tambor
With that, the first four-episode arc of The Clone Wars' final season comes to an end. The next begins on March 20 and will reveal what former Padawan Ahsoka Tano has been up to since she left the Jedi Order in season 5. Check out my recap that day.
