I am so sorry this ate my brain and then things ran away from me. I AM SORRY.
So. Anakin leads an army to retrieve his children and it’s this twisted version of everything Sidious ever wanted and he’s prepared for that.
But Sidious always underestimates how love changes things. And while he’s prepared to fight Anakin’s devoted army of former crechelings, he underestimates how that’s changed the rest of the Order.
Because Obi-Wan is quieter about whom and how he loves but doesn’t make it any less strong. When Obi-Wan loves someone it is unconditional and unyielding and he has never loved anyone as much as he loves Anakin Skywalker. Then the twins are born and Anakin is bashfully about it but he’s not ashamed and of course Obi-Wan has to know, he can’t imagine Obi-Wan not knowing his children (Obi-Wan totally already knows, he has been rolling his eyes about this for months and waiting for Anakin to come to him so he doesn’t spook him or for Padme to knock some freaking sense into him, which she does, because not-dying Padme is scary post-pregnancy and not willing to deal with the stupid anymore) and then Padme hands him Leia and everything stutters to a halt for a moment because oh, oh no, Anakin has found him another padawan.
There is no one Obi-Wan will ever love as fiercely as Anakin, except for Anakin’s children, who may as well be his own children. And he knows from the moment he first holds her that Leia will be the greatest Jedi he ever has a hand in raising.
(It becomes a joke among the Knights and Masters at the temple after the Skywalker twins arrive. If you even think that you might like to take Leia as your padawan, you can feel Obi-Wan glare at you no matter where he is in the galaxy.)
And when Sidious kidnaps Anakin’s children – his future padawan – Obi-Wan is the only Jedi in the galaxy who can put a hand on Anakin’s shoulder and say we need a distraction to do this safely, trust me to bring them home for you. Anakin will lead the frontal assault and tear down all of Sidious’ carefully constructed plans. Obi-Wan will sneak in and safeguard their children and bring them home.
Here’s what none of them expected:
When Luke Skywalker came screaming and red-faced into the world, an ancient, meddling, troll of a Jedi Master who had vowed never to take another padawan felt it and thought: fuck.
Whereas Leia is, even as a child, stubborn and willful and silk hiding steel, Luke is twin balls of sunshine. Raised among Jedi, he is so bright a presence it hurts. Even raised among Jedi, he wears his heart on his sleeve and has absolutely no guile and he pouts when the cafeteria doesn’t serve his favourite dessert but will cheerfully walk across the room and give it to someone else if he senses that person is still hungry. The first time Luke sees Yoda he stares at him, all big blue eyes and pudgy baby hands, then grabs his ears and won’t let go. Everyone is horrified. Yoda harrumphs at him and tell him, “Patience, young one.” He toddles after Yoda from the time he can crawl and no matter how grouchy Yoda seems he never actively dissuades him from it.
After the twins enter the temple, Anakin always knows not to worry if Luke is missing from the crèche. Yoda will escort him back sooner or later.
(He’s always much more worried when Leia disappears because, yes, Obi-Wan will bring her back but they’ll have always gotten into trouble in the meantime.)
Yoda does not confront Darth Sidious. Yoda does not lose his duel with the Sith lord and become diminished because of it. Yoda is with Obi-Wan, sneaking into his stronghold to see the twins safe. Yoda cannot go Sith hunting when Luke is in pain and gently clinging to him, his arms around his neck, bruised and bleeding and smiled at Yoda when he saw him because Luke knew he would come.
(Sidious cannot win, with them. Leia would risk her home being obliterated rather than betray her righteous cause. Luke would willingly walk into flames rather than give up on those he loves. It hurts, oh it hurts, to see the other in pain, but Leia can watch Luke being hurt and know there are more important things at stake than the two of them and Luke can watch Leia being hurt and trust that they will be saved.)
Sidious escapes but his Empire falls before it solidifies. He will never be as powerful as he needs to be.
(It’s Anakin who notices there is something wrong with the clones. He’s not their General but Obi-Wan is and Obi-Wan is a good general. When Obi-Wan is hurt, they’re all nosey and worried and Anakin – all but glued to his former Master’s bedside when it’s really bad and first and foremost a mechanic – can tell that something is wrong. He’s not always with them so it never becomes familiar, it never becomes normal, and it niggles at the back of his brain until he’s sitting in front of Obi-Wan’s bacta tank – old training bond humming between them because Obi-Wan hates drugs and hates being sedated and he stays quieter and heals faster if Anakin is there to keep him calm – and Rex walks in to check on the General and Anakin turns around to look at him and he sees it.
The Jedi Order quietly deprograms the clone army. They trace the chip back to Palpatine. Padme and Bail Organa and Mon Mothma start quietly amassing information against him and his allies – enough for criminal charges, pushing Sidious to show his hand and try to kidnap the twins.)
Obi-Wan takes Leia as his Padawan the second she’s old enough for it to be proper. They are scarily well matched. If he was the Jedi’s best hope to keep planets from succeeding during the war, together they can talk whole systems into rejoining the rebuilding Republic.
Yoda leaves Luke in the crèche until the day before his thirteenth birthday. Everyone is worried except Luke (who knows he is meant to be a Jedi and knows Master Yoda is meant to teach him and trusts this, since he was raised in the Temple. It’s easier to have faith when you’ve always had it and it’s never been wrong). Fourteen Jedi have tried to ask him to be their apprentice. Yoda bashed twelve of them over the head with his stick before they could and Luke turned two down himself, the last three days before his birthday. He spends his last day as a twelve-year old following his dad around, both of them a little clingier than usual. Anakin has always thought that Yoda intended to take Luke as his Padawan but he’s literally hours from aging out and he’s seriously considering comming Ashoka and begging her to come act as backup, when Luke suddenly hugs Anakin hard and quick and Anakin looks over and sees Yoda waiting in the doorway.
Anakin hugs Luke back very, very tightly and then he lets him go. Luke already has his few things packed and waiting. Yoda harrumphs at him. “Ready, you are, padawan mine?”
Luke’s smile is blinding. “Yes, Master.”
Leia talks star systems into rejoining the Republic. Luke returns the Fallen to the Jedi. Dooku is the first and most fleeting (having not been killed by Anakin) – having been betrayed and split from Sidious – Luke finds him when he’s dying and gets Yoda to him in time for him to pass them information on Sidious’ new schemes and die a Jedi, with his old master at his side. There are others, after that, who Fell during the war and didn’t think they could ever return from it. Luke, bright and shiny and full of faith, sees them, thinks, I can fix this, and brings them home one by one.
After the second Return, which is unavoidably public, Leia and Obi-Wan look at each other and enlist everyone they can to begin working to make Luke the new poster boy for the Order. Luke is intensely embarrassed by this and a bit bumbling and shy about it, which just makes it more attractive to everyone. It also keeps the spotlight well away from their rebuilding efforts, which are way easier when there’s less press exposure.
Sidious, who would still like to capture and corrupt the twins, eventually stops trying with Luke because there’s only a 50/50 anyone he sends after him will come back and between years of Yoda’s training (ie dodging his stick), Luke’s innate Force sense and his dumb luck he’s practically impossible to kill.
(Sidious dies ignobly at the hands of a new apprentice, one of the Fallen who Luke has been trying to save. His defeat was always going to be someone else’s redemption.)
