The first official negotiations between the Galactic Republic and the Confederacy of Independent Systems are taking place on the neutral planet Mandalore. Senator Padmé Amidala of Naboo, one of the delegates, is accompanied by Padawan Ahsoka Tano. The negotiations are at somewhat of an impasse because the Republic refuses to recognize the Confederacy as legitimate, when Lux Bonteri, son of murdered Separatist senator Mina Bonteri, bursts in on them. He demands that Count Dooku be brought to justice for murdering his mother. After Lux is arrested by the Separatist security for disrupting the proceedings, Padmé lets Ahsoka go after him to try and rescue him.
Lux is taken to the ship the Separatist delegation arrived on, where Dooku, via hologram, pronounces that he is to be executed. While he's doing this, Lux fiddles with a gadget he's wearing on his wrist. Before the sentence can be carried out, Ahsoka bursts in and rescues Lux, and they flee Mandalore in a Republic ship. On board the ship, Lux manages to stun Ahsoka. He tells R2-D2 she's fallen asleep, and changes the ship's course to head for the planet Carlac.
Ahsoka wakes up shortly after arrival to find Lux has gone outside to meet someone, and her lightsabers are missing. She tells R2 to look for them while she goes out to have a word with Lux. It turns out that Lux, wanting revenge for his mother's death, has teamed up with the Mandalorian terrorist group Death Watch and its leader, Pre Vizsla, who's had a falling out with Dooku since his last appearance. Ahsoka tries to warn Lux about their true nature, but he doesn't listen.
Lux tells the Death Watch Ahsoka is his "betrothed" when Vizsla's lieutenant Bo-Katan asks who she is. R2 comes off the ship having found Ahsoka's lightsabers, but she signals him to hide them so Death Watch doesn't see. Lux, Ahsoka and R2 are taken to the Death Watch camp. Ahsoka is thrown in with a group of captured Ming Po girls who have been forced into service, while R2 is ordered to fix up a bunch of droids the Mandalorian warriors use as target practice. At suppertime, the chieftain of the nearby Ming Po village, where the girls were abducted from, angrily bursts in and demands their return. Vizsla promises they'll be returned the following morning.
The following morning, the Death Watch, with Ahsoka and Lux in tow, descends upon the village. Vizsla murders the chieftain's granddaughter, one of the captured girls, in front of him with the Darksaber, and orders the village burned to the ground. Ahsoka intervenes, and kills several warriors with nothing more than farming equipment, revealing herself as a Jedi. She's captured and dragged back to the camp. Lux, by this point, is having serious second thoughts about this, and asks Vizsla to spare her, but he refuses. R2 takes the moment to return Ahsoka's lightsabers, having repaired the droids and recruited them as backup to attack Death Watch. In the ensuing fight, Ahsoka manages to fight Vizsla to a draw, and the trio escape the camp, and eventually Carlac.
Ahsoka asks Lux to come back to the Republic with her, but he refuses, instead leaving in an escape pod.
- Bald of Evil: Pre Vizsla is now rocking the skinhead look.
- Bullet Dancing: The Death Watch members do this with the droids they keep for target practice.
- Yet again, Vizsla, wielding the Darksaber, gets into a duel with a Jedi who's trying to protect a Non-Action Guy/Girl they have romantic tension with while attempting to flee the Death Watch camp. Only this time, Ahsoka has no reason to hold back because Lux, unlike Duchess Satine, is not an Actual Pacifist.
- Lux wants revenge against Dooku because he had Mina Bonteri murdered after she supported peace negotiations with the Republic.
- Doubling as a Call-Forward, this is not the first or last time R2-D2's wound up carrying the lightsabers of a Jedi that he's accompanying into the headquarters of an antagonist.
- The Cameo:
- Duchess Satine is overseeing the negotiations.
- The other Republic delegates are Mon Mothma and Bail Organa.
- Designated Girl Fight: Ahsoka vs. Bo-Katan while they're escaping.
- Fake-Out Make-Out: Ahsoka and Lux are arguing in a tent when he sees Pre Vizsla approaching from outside, so he kisses her so Vizsla doesn't hear anything giving away Ahsoka's Jedi status.
- Flirtatious Smack on the Ass: Ahsoka receives one from Bo-Katan and she did not like it.
- For the Evulz: The Death Watch's destruction of the Ming Po village.
- Good Scars, Evil Scars: Count Dooku gave Vizsla a scar underneath his right eye.
- Horrible Judge of Character: Lux Bonteri is extremely guilty of this, thinking he could trust Pre Vizsla and Death Watch.
- Impaled with Extreme Prejudice: Vizsla does this to Tryla, Chieftain Pieter's granddaughter, right in front of him.
- Improvised Weapon: Ahsoka kills several Death Watch commandos with farming equipment at the village.
- Noodle Incident: The last time we saw Death Watch, they were allies of the Separatists. We have no idea what caused their falling-out, other than that Count Dooku gave Pre Vizsla a nasty scar by his right eye during the process.
- Off With Their Heads: Upon getting her lightsabers from R2, Ahsoka cuts herself loose in one swing and beheads four Death Watch commandos.
- "Shut Up" Kiss: Lux to Ahsoka, for the above-mentioned reason of preventing Vizsla from overhearing anything that would give away her Jedi status.
- Snow Means Death: Carlac is a cold and snowy planet. There's death, lots of it.
- Undercover as Lovers: Lux tells Bo-Katan Ahsoka is his "betrothed" so they won't know what she actually is.
