"The Jedi's Return: A Second Encore" marks the thirteenth and concluding installment of the second season of the series LEGO Star Wars: The Freemaker Adventures.
In the aftermath of the Skirmish on Shantipole, the Freemakers, accompanied by Quarrie, sift through the debris of both the StarScavenger and the Arrowhead. Kordi Freemaker acknowledges their predicament on Shantipole, urging calm and assessment. Zander Freemaker emphasizes the destruction of their ship, the StarScavenger. Roger attempts optimism, noting the Arrowhead's demise as well. However, Kordi reminds them that M-OC has absconded with its crucial kyber crystal, which he intends to utilize in safeguarding the second Death Star.
Rowan Freemaker further explains that the second Death Star is operational due to his unwitting provision of the crystal planet's location to Darth Vader. Quarrie laments their inability to warn anyone. Roger interjects with a supposed silver lining, claiming a low probability of further complications. Kordi gently chides Roger's pep talk skills, while Quarrie emphasizes the inevitability of defeat through inaction. Rowan, noting the theft of essential components by M-OC, questions his ability to build anything.
Zander suggests his brother construct another "Ugly", with Kordi echoing the sentiment. Rowan resolves to visualize the final product, disregarding the limitations of the available parts. Harnessing the Force, Rowan crafts a new vessel from the wreckage. At Roger's request, he incorporates a more spacious charging station. Rowan's creation, an extended version of the StarScavenger, earns praise from Kordi and Quarrie, with Quarrie noting that the ancient Force Builders would have been proud. Zander commends his sibling's fusion of the best aspects of both ships, declaring their mission to save the galaxy. Roger expresses his satisfaction with the improved charging station.
Emerging from hyperspace via his hyperspace transport ring, M-OC arrives at the second Death Star, orbiting Endor. Within the Emperor's Tower, Emperor Palpatine approaches his throne, guarded by two Imperial Royal Guards. He expresses satisfaction with the unfolding events, confident in his acquisition of the Arrowhead and the Freemakers' demise. He anticipates luring the rebels into a trap through an attack on his fully operational Death Star. The Emperor also looks forward to Darth Vader's arrival with his son Luke Skywalker, whom he seeks to convert to the dark side of the Force.
The Emperor's contentment is disrupted by a squeaky throne, prompting a Royal Guard to apply oil. Before the Emperor can revel in his triumph, M-OC appears, cautioning him of a flaw in his plan to defeat the Rebellion. The Emperor dismisses the notion, attributing the plan's perfection to his own genius. When the Emperor protests M-OC's presence due to an expected guest, M-OC reveals his acquisition of the Arrowhead crystal, but the Emperor's focus remains on Skywalker.
M-OC informs the Emperor of his intention to use the Arrowhead crystal to fortify the Death Star's main reactor against rebel attacks, should the shield generator on Endor fail. Preoccupied with Skywalker, the Emperor grants M-OC free rein. M-OC departs, leaving the Emperor to await Darth Vader and Skywalker. Shortly thereafter, M-OC pilots his arachnid starship into the Death Star's main reactor core, employing the Arrowhead's kyber crystal to create a deflector shield around it, vowing unwavering service to his master.
Aboard the newly rebuilt StarScavenger on Shantipole, the Freemakers brace themselves for a turbulent ascent through the atmosphere. Kordi jokes about leaving her stomach behind, while Roger points out their need to breach the atmosphere. Quarrie assures them that they have enough momentum to break through. As the StarScavenger hurtles into the charged atmosphere, the ship loses power due to the electrical storms and plummets downward. Roger tumbles as the ship descends, while Quarrie quips about his preparations.
Zander struggles with the controls. Fortunately, the StarScavenger regains power and narrowly avoids crashing into the Shantipole landing field. The Freemakers rocket through Shantipole's atmosphere into space. As they ascend, Kordi tells Zander that she teases him a lot but that today he really is "Zander Freemaker Superstar Pilot Guy." Zander thanks Kordi and asks where they are piloting to. Quarrie informs them of their destination: Sullust, where the rebel fleet is gathering.
However, they discover that the rebel fleet has already departed. Quarrie suggests contacting Admiral Ackbar, but the Freemakers and Roger are hesitant due to their past mishaps, including the loss of the Arrowhead. Kordi instead reaches out to Lieutenant Valeria, reasoning that she would be less inclined to punish them severely. Valeria is initially reluctant to engage, fearing court-martial. She reveals to Kordi that the rebel fleet is en route to Endor for a surprise attack on the second Death Star.
At that moment, Valeria and the rebel fleet emerge from hyperspace above Endor. Rowan attempts to warn Valeria about the fully operational Death Star and M-OC's presence, but his message is interrupted by static. Valeria discovers that the Death Star's shield are up while Admiral Ackbar realizes too late that they have stumbled into a trap. Rowan, Kordi, and Zander realizes that the rebels' sneak attack has backfired.
Zander proposes setting a course for Endor, but Roger questions their purpose. Zander admits uncertainty but insists on preventing the Rebellion's destruction. Quarrie reminds them of the StarScavenger's inferiority to the Death Star, and Rowan adds M-OC to the equation. Kordi suggests they need something to even the odds. Rowan realizes that they need the Kyber Saber. Roger points out that it is ironic that they are over the planet where he destroyed it. Roger thinks the Saber would come in handy right now.
Rowan clarifies that he didn't destroy it, despite appearances. He assures them that he can still sense the kyber crystals. Rowan says that destiny led them to this place and to this moment. He says he has to get the Kyber Saber. The Freemakers land on Sullust. Rowan stands on top of a cliff and uses the Force to summon the pieces of the Kyber Saber from the lava pit and reassemble it. Rowan grabs the hilt of the Kyber Saber but it is burning hot. Roger, who has metal hands, retrieves the weapon and tells Rowan to let's go and save the Rebellion.
As they traverse hyperspace, Zander instructs everyone to prepare for action. Rowan affirms his readiness for anything. Upon exiting hyperspace, the StarScavenger finds the rebel fleet under assault by Imperial forces. The Freemakers evade two TIE interceptors and reach the second Death Star, still shielded by the Endor generator. With the shield preventing starship entry, Rowan decides to utilize the StarScavenger's newly integrated embersteel Blade to breach it. When Zander points out that it needs a kyber crystal, Rowan uses the Kyber Saber to power the Blade.
The StarScavenger employs the Embersteel Blade to create an opening in the shield. However, the ship loses its lateral controls and crashes into a hangar bay, ploughing through several parked TIE fighters. Kordi and Zander feign surrender to the stormtroopers, but Rowan employs the Kyber Saber to assemble a massive blaster from nearby crates, scattering the troopers. He also traps some storm troopers inside solar collectors. Rowan is jubilant about wielding the Kyber Saber but is stunned by a stormtrooper, who is able to shoot straight.
The stormtroopers quickly take the Freemakers and Quarrie prisoner. The stormtrooper commander tells his men to take the prisoners to the detention level where Lord Vader will deal with them later. He also tells an Imperial weapons technician to deliver the Kyber Saber to the Emperor at once. Inside the detention cell, Roger recalls his earlier calculation that the odds of things getting worse were 7,826 to once. Roger quips about them beating the odds.
Kordi fears that if the rebels lose the battle while Rowan adds that the Empire will vaporize them. Zander refuses to give up hope and hopes that the rebels will knock out the shield and blow the Death Star to dust. Kordi points out that they will get blown to dust with it. A despondent Zander sees her point.
Suddenly, the cell doors swing open, and an Imperial weapons technician enters, carrying the Kyber Saber. She declares their immediate need to escape and frees them. When Zander inquires about her identity, the technician removes her helmet, revealing herself as Zander's love interest Becky Smoochenbacher. She professes her love for Zander. Becky explains that she joined the Empire when he left the Wheel but decided to change sides after learning that Zander fights with the rebels. She tells Zander that she has had a crush on him forever and the two embrace. Becky instructs the Freemakers and Quarrie to locate a ship, promising to meet them on Endor. Zander is smitten and collapses.
After escaping the detention block, the Freemakers and Quarrie sneak up on a command center. The Imperial officers stationed there have just received word that the rebels have taken out the Endor shield generator. After the officers head down a turbolift to battle stations, Quarrie tells them that there is nothing better than a huge galactic battle to provide a distraction. Kordi then contacts Lieutenant Valeria and tells them she is on the Death Star. When Admiral Ackbar orders the rebel fighters to enter the Death Star, she tells the Freemakers to flee faster than a womp rat because they are coming into the reactor core.
The Freemakers wants to escape but Rowan reminds them that M-OC is still committed to ensuring the Emperor's victory. Rowan realizes that M-OC is going to try and stop the rebel attack at the Death Star's reactor core. Quarrie agrees that the main reactor core would be a good place to mount a last line of defense. Rowan says that he can sense M-OC and that he must stop him. Zander and Kordi says that they will defeat M-OC together but Roger is unwilling to risk the lives of his family. He uses the Force to shove them into a turbolift and tells them to take care of themselves because he has a job to do, as he takes the other turbolift down on his way to the Death Star reactor core.
Rowan confronts M-OC at the Death Star reactor core. M-OC remarks that he calculated that Rowan had a one in three chance in coming. M-OC is confident that the rebel attack will face because he believes he is invincible in his current form. Rowan is defiant and attacks M-OC with the Kyber Saber. While Rowan advances on M-OC, Zander says that he can't believe what Rowan did to them. Roger is not surprised since he knows Rowan well. Exiting the lift, the Freemakers try to find their ship StarScavenger only to run into three stormtroopers, who chase them.
While recognizing that the Kyber Saber has upgraded Rowan's powers, M-OC taunts him that he is invulnerable in his arachnid form. Rowan is unable to breach the deflector shield generated by M-OC's Arrowhead kyber crystal. M-OC unleashes a multi-faceted attack with all his weapons and blasts at Rowan. Meanwhile the other Freemakers lead their stormtrooper pursuers on a chase and cross a bridge. After they have crossed, Kordi manages to stop the advance by threatening to touch the control panel. When one of the stormtroopers says that they will still blast her, Kordi deactivates the bridge, causing them to plunge into the depths of the Death Star. Kordi quips about the trooper's honesty.
The Freemakers reach the hangar bay where the StarScavenger is parked and fight the stormtrooper sentries stationed there. They then depart aboard their ship with Kordi firing up the converters and angling the deflectors. Zander tells the others to hold on to their bricks, as the StarScavenger departed on its way to the Death Star's reactor core to pick up Rowan as he defeats M-OC. In the Death Star's reactor core, M-OC manages to drive Rowan to the edge of the platform. Rowan manages to hide behind the reactor core. M-OC boasts that as long as he has his kyber crystal, he is invulnerable.
Realizing that he has been going about it the wrong way, Rowan uses the Kyber Saber to call to M-OC's Arrowhead crystal. When M-OC questions his unorthodox move, Rowan retorts that he is taking back his crystals. A tug of war between the two ensues. M-OC says they have reached a stalemate that he cannot win but Rowan counters that he is trying to distract him from protecting the reactor core. M-OC vows to finish Rowan quickly and taunts Rowan about his lack of focus.
M-OC attacks Rowan with his flamethrowers, missiles, and many other countless weapons which Rowan is able to avoid. However, M-OC uses hologram recordings of his siblings Zander and Kordi to distract Rowan and blasts him with a sonic cannon, knocking the Kyber Saber out of his hand. M-OC pins Rowan down with one of his magnetic legs and taunts him that just as he predicted, family is his weakness. However, M-OC is distracted along with Rowan saw the Emperor plunging to his death down the Death Star reactor core. With M-OC distracted in which that he's shocked for the loss of the Emperor, Rowan hurls the Kyber Saber into M-OC's Arrowhead crystal.
M-OC says this was not in his calculation before exploding, disabling the deflector shield protecting the reactor core. Rowan realizes he won but that the rebels will blow up the second Death Star with him on it. Rowan is about to resign himself to death when he hears the screech of the StarScavenger's engines. Zander says they have got their little brother while Kordi opens the scoop. Rowan boards the StarScavenger shortly before the Millennium Falcon and several rebel starfighters arrive and blast the reactor core. The Freemakers and Quarrie escape the second Death Star as it explodes. Rowan is delighted his family came back for him and embraces them. The StarScavenger joins the rest of the rebel fleet in fleeing to Endor.
The Freemakers, Quarrie, and Valeria partake in the rebel celebration at Bright Tree Village. Quarrie offers design suggestions for the X-wing to Valeria. Zander and Becky share a kiss while Roger chats with C-3PO and R2-D2, asking what they did to advance the cause of freedom.
Rowan asks his siblings where they go from here. Zander says they don't know because it is a pretty big galaxy. Kordi says that she has a feeling that it would need a lot of rebuilding. Roger quips that it would need a whole lot of rebuilding. Rowan suggests they could help with that.
Rowan then meets Luke Skywalker, whom he calls Master, and shows him his Force Building powers by levitating and reassembling a chest in the presence of the rebels. Wedge Antilles is impressed and asks who he is. Kordi tells Wedge that Rowan is their brother. X-wings fly overhead as fireworks explode in the skies above Endor.
