He did not reveal the truth for the same reason that Obi-wan Kenobi did not reveal the full truth. R2-D2 was in on the scheme to keep the secret away from Luke and Leia.
secondly, in Legends, R2 was given programming that actually restricted him. from sharing any information with Luke or Leia. about their parents or relation to one another.
So Owen had no idea his "new" protocol droid's name was C-3PO. A counter to that might be asking why Owen didn't recognize C-3PO's distinct voice, but again, it's worth remembering Owen hadn't seen C-3PO in more than 20 years. It's possible Owen simply forgot what C-3PO's voice sounded like.
Since Bail Organa had C-3PO's memory wiped previously in order to prevent him from spilling the secret of Leia's parentage, it could be that this was a semi-regular occurrence for the droid given he couldn't be trusted to keep quiet about things.
Why Didn't Darth Vader Remember C-3PO in The Empire Strikes Back? Star Wars Explained (Legends)
Does R2-D2 know Luke is Anakin's son?
R2-D2 was present when Padmé gave birth to Leia and Luke, so he knew Luke was Anakin's son – but what he didn't know was that Anakin became Darth Vader. In addition to that, Anakin's fall was surely a painful event in R2-D2's life, one that he definitely wouldn't like to remember or even talk about.
in the Dark Horse comic series star Wars Tales, which is now part of legends, it's revealed that Darth Vader did recognize C. 3PO on Cloud City. when 3PO was shot by Stormtroopers, his parts were brought before Vader. because the Imperials thought he could hold valuable.
The base assumption of why Obi-Wan doesn't remember R2-D2 -- in light of the prequels -- is that Obi-Wan is feigning ignorance in A New Hope to downplay the importance of the droid's arrival.
Summary. Darth Vader's failure to recognize Leia as his daughter in Star Wars: A New Hope stems from George Lucas's late decision to make Luke and Leia siblings. Leia's Force abilities and her lack of awareness of her true identity also contributed to Vader's inability to sense their familial connection.
Why is C-3PO forbidden to translate the Sith-Runic language? Rather simple. All protocol droids have the ability to translate. But a Senate ruling put in a rule that required all translating droids to be forbidden to translate, and if such system is overridden, to erase the droid's memory.
Shortly after the Clone Wars, C-3PO's memory was erased, though R2-D2's memory was not. C-3PO and R2-D2 were assigned to the Alderaan cruiser Tantive IV, where they served senator Bail Organa for nineteen years, assisting in his fledgling resistance movement against the Galactic Empire.
Obi-Wan Kenobi has no idea who C-3PO is when they meet in “Star Wars: A New Hope” even though the prequel trilogy later told us that the two certainly knew each other.
C3PO had his memory erased so he doesn't remember at all. And I agree with the above statement about Obi-Wan and R2 having an off set agreement about there friendship. Also Obi-Wan and C3PO had plenty of meetings in the first 3 movies.
In Star Wars, younglings were traditionally recruited into the Jedi Order from an early age — so young that 9-year-old Anakin Skywalker faced opposition as being too old to train. However, during the original trilogy, Yoda and Obi-Wan Kenobi resolved to train a 19-year-old Luke Skywalker.
Summary. Anakin's fall to the dark side had a heartbreaking effect on R2-D2, who felt abandoned and ignored by his former master. Star Wars droids like R2-D2 rarely receive emotional depth, making R2's words about Anakin's betrayal even more tragic.
Although Lucas portrayed R2-D2 as a defiant droid who refused to listen to his master's orders, the theory video claims R2-D2 wouldn't stay with the ship because the last time he did that, Anakin never came back.
Darth Vader didn't learn he had a daughter until Return of the Jedi, when he stood before Emperor Palpatine. The Emperor's power probed Luke's mind, attempting to goad him to fall to the dark side, and he discovered Leia's existence. "Sister," the Emperor taunted.
Vader was hunting down the pilot who blew up the Death Star, and hired Boba Fett to find them. Boba was unable to, but he did give Vader a name: “Skywalker.” This, combined with his knowing Luke was Force-sensitive and had been trained by Obi-Wan, was what made him realize the truth.
You saw how Luke's attitude completely changed when he realised that was actually Yoda and so did Yoda's behaviour. As for the r2 thing, is incredibly likely he just suspected R2 had had his memory wiped several times since they last saw each other.
Darth Vader can not use force lighting, because of his severed arms. Robotic hands can't summon the force lighting. However Darth Vader can still use other forms of the force, such as force choke.
Every time she speaks, he remembers Padmé. Fighting alongside Sabé reminds him of fighting alongside his wife. While that is certainly painful enough, it's also reminds Vader of the man he used to be, a past he had long ago attempted to kill and bury. However, the memory of Padmé via Sabé won't let his past stay there.
She senses Anakin when she reaches out to the pilot — and Vader realizes that Ahsoka, his former Padawan, lives on. In Season 2, Episode 18, “Shroud of Darkness,” Ahsoka's guilt manifests as a vision of Anakin, who's angry with her for leaving him all those years ago.
On a mission to Pasaana, C-3PO discovered safeguards in his programming made it impossible for him to translate Sith runes that could help the Resistance locate the legendary planet Exegol. With the fate of the galaxy hanging in the balance, C-3PO reluctantly agreed to have his memory erased so the runes could be read.
