" Sabine leads a mission to free her father from the Empire , but finds that a past mistake has been resurrected with deadly consequences . " Plot summary . Part One . Prison raid . Sabine Wren , Ezra Bridger , and Chopper are hiding in a trench on the planet Mandalore , watching an Imperial prison in the distance . There ' s been intelligence that Sabine ' s father , Alrich Wren , has been moved to the remote prison from the Mandalorian capital , Sundari . When Kanan Jarrus , in a different trench with Fenn Rau , asks whether Sabine doesn ' t find it suspicious that her father was moved out here , she explains that her father still has friends in the capital , so the Empire likely moved him here to cut him off from them . Ezra has been loaned a jetpack , and he ' s not sure how much use he ' s going to be with it . Sabine tells him that since he ' s a Jedi , he should " pick it up on the fly . " Chopper unnecessarily attempts to explain the point to Ezra . Sabine climbs out of the trench , and is spotted by the stormtrooper s on guard . She takes out the Darksaber and ignites it , and Ezra and the Clan Wren warriors waiting in the trench climb out as well . Sabine gives a battle cry , and the warriors charge forward . Kanan and Rau are confronted by three Jumptrooper s , and the Jedi Knight takes them down singlehandedly by Force jump ing onto one , slashing at their jetpack , and then jumping onto another , prompting Rau to mutter " Showoff . " During the fight , Ezra attempts to use his jetpack , and doesn ' t fare particularly well , to the confusion of two stormtroopers who see him . The leader of the Jumptroopers guarding the prison contacts the governor of Mandalore , Tiber Saxon , and informs him of the attack . Saxon informs the soldier that he is sending reinforcements . A " Gozanti " - class cruiser promptly arrives with two All Terrain Defense Pod s . Sabine comments to Ezra that the fight just got more interesting . While fighting the AT - DPs , Sabine is knocked down , and some Jumptroopers manage to stun and hold her at blasterpoint , and the Jumptroopers ' leader orders Ezra and the other attackers to surrender . With excellent timing , a missile hits one AT - DP and three Mandalorian warriors in blue swoop in , the woman in charge yelling at them to stop standing there , and the fight begins again . Rau tells Kanan that the newcomers are Clan Kryze . The Imperials are swiftly routed , but it ' s discovered afterward that the prison is empty . The Kryze warriors land , and their leader explains that the prison was a trap , Sabine ' s mother Ursa Wren sent them as reinforcements , and that Ursa had found out that Sabine ' s father had been moved , but was unable to directly contact them due to Imperial jamming . Sabine asks the woman who she is , and she removes her helmet . Fenn Rau introduces the red - haired woman as Lady Bo - Katan Kryze , who is seen by many as the rightful leader of Mandalore , as the Jedi made her regent of the planet near the end of the Clone Wars . Ezra asks what happened , and Bo - Katan explains that she refused to do the Emperor ' s bidding , and was betrayed by Clan Saxon and forced out of power . Sabine offers her the Darksaber , telling her that she should have it , and Bo - Katan turns it down , stating that she had her chance and that she is not her sister . Shortly after , Ursa and Tristan Wren arrive , having been contacted by Rau . Ursa reveals that they ' ve found out that her husband is being transported to Sundari for a public execution . Attack on the convoy . Sabine , Rau , Bo - Katan and Ezra crouch on the edge of a canyon , waiting for the smoke of Ursa and Tristan ' s attack , intended to divert the prisoner convoy carrying Alrich Wren into their path . Meanwhile , Kanan talks to Hera Syndulla via hologram . Hera reminds Kanan that they can ' t stay very long on Mandalore and have to return after they ' ve freed Sabine ' s father , as it was difficult enough persuading Mon Mothma to let Kanan , Ezra , and Chopper go there in the first place . Kanan tells Hera that Alrich is important to the Mandalorians , and she responds that the Spectres are valuable assets to the Rebel Alliance . Kanan is somewhat perturbed by being referred to as an " asset " , and diverts the conversation to asking Hera how she feels about " his " absence . Hera asks if they are still talking about the mission , and Kanan states that that depends . They sign off , Hera asking Kanan to stay safe . Sabine points out a now - visible smoke plume to Ezra . The prisoner convoy diverts into the canyon , as planned . Rau scans it , and detects a single unarmored passenger in the middle transport , which is the most heavily guarded . Sabine outlines the plan : one of them will sneak in and attack the middle transport after the rest of them cause a diversion . Ezra asks if this part of the plan has his name on it , and Sabine points out how bad he was with his jetpack . He counters that he ' s improving . The attack begins with Sabine leaping off the cliff , swooping in and attacking the scout trooper s on speeder bike s . She strikes the windscreen of the middle transport with a paint bomb , which causes her father to realize she ' s present . Captain Hark , the leader of the Imperial Super Commando s guarding the convoy , reports the attack to Governor Saxon , who responds by informing him he is sending reinforcements , and ordering the weapon to be prepared . As Sabine , Bo - Katan , Rau and Kanan attack the convoy , Ezra flies in from behind and grabs on to the middle transport , clinging to the underside and stabbing into the controls with his lightsaber . When one of the super commandos looks underneath , however , Ezra has already moved to the back of the transport , out of sight . During the attack , Sabine acquires a speeder bike , and Kanan fights stormtroopers atop the first troop transport . Ezra finally gets inside the transport as it hurtles towards a cliff , and takes out the drivers and super commandos inside . Alrich asks if Ezra is with Sabine , and the Padawan responds affirmatively , before clarifying that he ' s not with her in the romantic sense . Ezra cuts Alrich loose and gives him his jetpack , explaining that he ' s better off without one . As the transport hurtles off the cliff , Ezra pushes Alrich out the door , and he flies up to the top of the cliff . Ezra leaps out the door , and uses a series of Force jump s up the three falling transports to reach the top of the cliff , where he nearly falls before being caught by Sabine . Alrich is happy to see Sabine , and the two of them quickly get into a discussion about art . Sabine contacts her mother to report that the rescue was successful . Ursa responds that they will have two victories to report today . Tristan cuts in to report that reinforcements have arrived , and Sabine wonders why the Empire would reinforce a losing battle . He reports that the reinforcements are a single scout walker of an unusual design , and Ursa scoffs and orders it destroyed . Then Sabine hears a familiar sound over the comlink , panics , and tells her mother and brother to get out of there . The comlink then cuts out , before a flash of a distant explosion is seen in the distance . Horrified , Sabine takes off for the battle site , and the others follow on jetpacks and the speeder bike . They arrive to find the disintegrated bodies and damaged armor of several Clan Wren warriors . Bo - Katan asks where the bodies and survivors are , and what could have done this . Alrich explains that a weapon was responsible , a weapon designed by his daughter . Sabine collapses , crying , over one of the piles of armor . Part Two . Pursuit . Ezra tells Sabine it ' s not her fault , and she explains that it is , because this was the work of her weapon , the one she built at the Imperial Academy . She collapses , crying , because she believes that her mother and brother are dead because of her actions , and her weapon . Shortly , voices are heard from nearby , and Ursa and Tristan walk up . The Count ess is visibly injured , and she explains that Sabine ' s warning gave her and Tristan enough time to take cover , as they were on the edge of the weapon ' s area of effect . Sabine is incredibly relieved , and runs over to them . However , the respite is short - lived , as Rau spots approaching Imperial super commandos . Fighting ensues as Sabine , Bo - Katan , Rau , Kanan and Ezra attempt to get the injured Wrens out of the area . The speeder bike is quickly destroyed , and Ezra notes that they ' ve been cut off as three TIE fighters swoop in . Fortunately , a " Gauntlet " fighter belonging to Bo - Katan ' s people arrives , shooting down one of the TIEs , and everyone climbs aboard . As the " Gauntlet " flies into the upper atmosphere , the two remaining TIEs pursue , one landing a hit on the ship . Rau , piloting , notes that their weapons have gone offline . Sabine tells him that she can keep them aloft , but says that they can ' t take another hit like that . Down in the hold , the bay doors open as Ezra tells Bo - Katan that they don ' t have any weapons . She responds that a Mandalorian with a jetpack is a weapon , and leaps out . Ezra , following , grumbles that he isn ' t Mandalorian and doesn ' t want to be one . Bo - Katan flies to one of the TIE fighters and grabs on . Ezra , meanwhile , hurtles about on his jetpack and winds up pressed to the windscreen of the other TIE , to the pilot ' s confusion . Bo - Katan opens up the hatch of her fighter and drops in a grenade , flying away as it explodes . Ezra is shaken loose from the other TIE , and as it flies off he manages to use his jetpack ' s rocket against it . The two of them fly back onboard the " Gauntlet " . Sabine ' s creation . Saxon reports to Grand Admiral Thrawn , via hologram , about the test of the Duchess , showing him a video of the weapon being used against the Clan Wren warriors . Thrawn notes that the weapon turns Mandalorian armor from a strength into a weakness , by targeting the beskar alloy it ' s made of , and asks Saxon what his late brother would think of him betraying his culture like this . Saxon responds that Mandalorian culture must adapt to survive . Thrawn states that the weapon does not have as great a range as he expected , which Saxon had been attempting to conceal . The Grand Admiral tells Saxon that the mind that designed the weapon is their best option for fixing it , and suggests he needs Sabine . After Thrawn signs off , Saxon orders Captain Hark to find the former Imperial cadet . Tristan tells Sabine that she told them she destroyed the weapon , and she responds that she " did " , but the Empire must have rebuilt it . Bo - Katan grabs Sabine and slams her into a wall before she demands to know why Sabine made a weapon that would target Mandalorian armor , which she considers an abomination that only a coward would make . Sabine explains that she was young and arrogant , seeking a challenge . She had sabotaged the prototype and erased the plans before she left the Imperial academy , and states that the Empire must have rebuilt the weapon . Ezra , noting that Sabine ' s weapon targets the material the Mandalorians ' armor is made of , asks why they don ' t just make their armor out of something else . The Mandalorians all stare at him , shocked by his suggestion . Sabine explains that her armor was originally forged 500 years before , and it carries the history of its previous owners with it . Alrich explains that for Mandalorians , their armor is a legacy and who they are . Arriving at Bo - Katan ' s camp , Sabine does not receive a warm welcome , as she is called a traitor by the warriors there . Ursa , disembarking from the ship , announces that attacking Sabine will bring down the wrath of Clan Wren on the perpetrators . Sabine owns up to her past misdeeds , and explains that the warriors have a choice : to attack her , or help her destroy her weapon once and for all . Bo - Katan backs her up . Planning the attack , it ' s decided that they will sneak aboard Tiber Saxon ' s Star Destroyer near Sundari , breaking into two teams : one to destroy the weapon , the other to erase the plans from the Imperial database . Rau wonders if the weapon could be used against the Empire , and Sabine seems tempted , noting that she ' s thought about it , but insists they must destroy it . Ursa offers to lead the team that will destroy the weapon , but Rau points out that she can barely hold a blaster , and Alrich and Tristan hold the Countess back . Kanan , Ezra and Chopper volunteer to erase the data . As Sabine begins to go over the details with the others , Rau takes Bo - Katan aside and tells her that he ' s surprised at how well she ' s responding to Sabine . Bo - Katan responds that she thinks Sabine has a lot of potential , and Rau agrees . Dealing with the Duchess . After dark , the strike team approaches Saxon ' s Star Destroyer by jetpack , and in Chopper ' s case rocket booster . They slip into the hangar , and sneak through the crates and vehicles stored there . Rau notes that the weapon ' s power core is missing , and Sabine guesses that the Duchess must be on the upper level . Bo - Katan is incredulous that Sabine named the weapon after her sister , the late ruler , and Sabine responds that it was one in a series of bad decisions . Once members of the team are spotted , a firefight begins almost immediately . Kanan , Ezra and Chopper depart the hangar in search of the databases while the Mandalorians stay and fight . Sabine and Bo - Katan go to the upper level in search of the arc generator . Finding it , they are ambushed by Saxon , who wants Sabine to repair her weapon and bring it up to full capacity . Meanwhile , Kanan and Ezra fight stormtroopers while Chopper plugs in and begins erasing the designs . Ezra attempts to contact Sabine and realizes she ' s in trouble , so Kanan tells him to go help her . Saxon shocks Sabine and Bo - Katan with the weapon , demanding she fix it . Hark , who accompanied Saxon , protests with his decision , stating that the Empire would most likely use it against all Mandalorians once it was at full power . Saxon , who is now annoyed by Hark ' s protests , also has the machine zap him , stating that he is the Empire . Saxon himself is unaffected as he is wearing Imperial armor . In the cargo hold , Ezra runs into Rau and Tristan , who is surprised that deleting the data was the easier mission . As the two begin to banter , Rau tells them to knock it off , as the Mandalorians are still dealing with the Imperial walkers . Still being zapped by the Duchess , Saxon stops the machine , giving the three Mandalorians a moment of respite . Sabine reluctantly agrees to help Saxon fix the machine , despite Bo - Katan ' s protests . Saxon smirks , believing that he finally has the upper hand , as Sabine adjusts the weapon . When Saxon reactivates the weapon , it zaps him and two stormtroopers instead . Sabine explains to Saxon that she readjusted the weapon to target anyone wearing Imperial armor instead , and tells him that the voltage isn ' t enough to kill him , just to make him suffer . The Duchess ' reach extends throughout the Star Destroyer , incapacitating anyone wearing Imperial armor , and forcing Ezra to fling off his repainted scout trooper helmet . Sabine thinks of killing Saxon by electrocuting him to death with the Duchess , but Bo - Katan stops her , stating that doing this would make her like the Empire , fighting with cowardice , and that she should fight with honor , like a true Mandalorian . Sabine realizes her mistake and shuts the machine off , while Hark flees the room . She slashes the weapon with the Darksaber , breaching its power core , just as Ezra arrives . The three quickly flee , and gather up the rest of the strike team , as the weapon ' s explosion will destroy the Star Destroyer . The strike team exits the same way they came in , as Saxon ' s warship crumbles behind them . Passing on the Darksaber . Arriving back at Bo - Katan ' s camp , Sabine tells her that she has proven she is the rightful leader . Bo - Katan is uncertain , as she had used it before without success , but Sabine and Ursa tell her that there are people willing to follow her . Sabine opens the " Gauntlet " ramp , revealing a gathering of warriors , including representatives from many other clans . Warriors from clans Vizsla , Rook , Eldar and Kryze , and Rau , the only survivor of the Protectors , tell Bo - Katan they are willing to follow her . Ursa adds in Clan Wren to the list . Bo - Katan finally accepts the Darksaber , in her sister ' s memory , for her clan , and for all of Mandalore , igniting the blade as the warriors kneel . Ezra looks at Sabine with a smile as he nodded and she smiles back to him .
