Varför "göm" Lukas från sin far någonstans Anakin vet?

Ärligt talat, detta är en dålig artefakt av en retcon av vad Lucas ursprungligen var tänkt som backstory för Luke och hans familj.

Baserat på noterna och de ursprungliga novellerna finns det inga bevis för att Anakin ursprungligen var avsedd att vara från Tatooine, och Owen Lars var inte anknuten till Anakin på något sätt. Owen var avsedd att vara Bens bror.

Det här uppenbarligen förändrats när prequelerna rullade runt, men går efter den ursprungligen avsedda backstoryen, gör allting bättre med att Ben gömmer Luke på sin egen hemplans, bort från Anakin.

Från de antecknade skärmdisplayerna:

It was decided during story meetings that Uncle Owen was in fact Ben's brother. Owen always resented Ben for imposing Luke on them, and now Ben is taking the blame for what is happening and is feeling guilty.

De ursprungliga novellerna återspeglar detta. Från en 1993 (läs: pre-SE, pre-prequels) utskrift av Return of the Jedi novellering:

Ben continued his narrative. "When your father left, he didn't know your mother was pregnant. Your mother and I knew he would find out eventually, but we wanted to keep you both as safe as possible, for as long as possible. So I took you to live with my brother Owen, on Tatooine... and your mother took Leia to live as the daughter of Senator Organa, on Alderaan."

• Tatooine är fysiskt långt ifrån riket
• Tatooine styrs av Huttsna som sannolikt inte kommer att välkomna en väsentlig imperium närvaro på planeten
• Tatooine är redan besatt av Force (på grund av Anakins association med planeten)
• De har helt enkelt brist på säkra alternativ under de senaste händelserna

“To Naboo, send her body,” Yoda said. “Pregnant, she must still appear. Hidden, safe, the children must be kept.”
“Someplace where the Sith will not sense their presence,” Obi-Wan said.
“Split up, they should be.”
Bail Organa raised his head. “My wife and I will take the girl. We’ve always talked of adopting a baby girl. She will be loved with us.”
Hidden in plain sight, Obi-Wan thought, and nodded. “What about the boy?”
“To Tatooine. To his family, send him.”

Remembering that harsh, dry planet, Obi-Wan winced. But there was nowhere else, and Tatooine was a world on the margins — the Hutt crime lords who ruled it had never been part of the Galactic Republic, and they would keep their distance from the Empire as well. “I will take the child there, and watch over him,” Obi-Wan said. He looked at Yoda, wanting reassurance he knew Yoda could not give him. “Master Yoda, do you think Anakin’s twins will be able to defeat Darth Sidious?”

officiella novellering erbjuder också några andra orsaker;

• Barnet måste höjas i en kärleksfull miljö.
• Att leva på Tatooine kommer att erbjuda Luke möjligheten att växa upp i en liknande miljö till sin far, både fysisk och känslomässig seghet.

Bail stood, a little jerkily, as though he simply could no longer keep his seat. His flush had turned from embarrassment to pure uncomplicated joy. “Thank you, Masters-I don’t know what else to say. Thank you, that’s all. What of the boy?”

“Cliegg Lars still lives on Tatooine, I think-and Anakin’s stepbrother … Owen, that’s it, and his wife, Beru, still work the moisture farm outside Mos Eisley …”

“As close to kinfolk as the boy can come,” Yoda said approvingly. “But Tatooine, not like Alderaan it is-deep in the Outer Rim, a wild and dangerous planet.”

“Anakin survived it,” Obi-Wan said. “Luke can, too. And I can-well, I could take him there, and watch over him. Protect him from the worst of the planet’s dangers, until he can learn to protect himself.”
