So, Yoda decided to spend time away and rejuvenate his connection with the Force. Yoda's decision was made on the basis that if Luke and Leia were meant to become Jedi, the Force will guide them on their way!
Yoda lists several specific reasons why he's reluctant to train Luke. He's impatient, angry, reckless, and constantly looking to the future at the expense of the present. In short: He felt Luke wasn't ready.
Obi-Wan could not adopt Luke because Owen and Beru raised him. His Uncle was there in the beginning, in the father role. That is why. Luke's story comes first.
Much like Anakin, Grogu was too emotionally connected to his parent to totally commit to his Jedi training. Grogu chose to leave Luke and the Jedi behind when presented with the opportunity.
First, Yoda didn't want to train Luke at first because he believed he was too reckless and would go down the same path as Anakin. He saw the many similarities between them and didn't want to risk it.
Yoda held the title of Grand Master of the Jedi Order since the days of the High Republic Era. At some point, Yoda took on a human named Kantam Sy as his Padawan.
Vader and Palpatine didn't know Yoda trained Luke because Yoda concealed his presence from the Force. They knew about Obi-Wan, but both Vader and the Emperor thought Obi-Wan was the last Jedi. Even in the "Return of the Jedi", Vader and Palpatine thought Luke's skills derived from Obi-Wan.
While fans don't know the state of Grogu's well-being in the sequel trilogy, his ties to Mandalore might explain why Kylo Ren doesn't kill him. It's likely Grogu stays with Din Djarin and the Mandalorians, and never returns to embark on his training with Luke.
It was believed that Grogu would eventually become a victim of Kylo Ren's destruction of Luke's Jedi Order. However, The Book of Boba Fett revealed that Grogu chose to follow the Way of the Mandalorian rather than become a Jedi, sparing him from Kylo Ren's wrath.
As depicted in "Chapter 20: The Foundling," Grogu was rescued from the attack on the Jedi Temple by Jedi Master Kelleran Beq. Beq completed the daring escape that got Grogu to safety, then escaped the attack with his life.
His only weakness proved to be a soft spot for his son, Luke, which led to him chucking Emperor Palpatine into oblivion, before he himself died a redeemed, but one-armed, hero.
For years, Vader hated Obi-Wan, having been struck down by his mentor and left for dead while also believing the Jedi had worked to turn his true love Padmé against him.
Theory 1: Leia Doesn't Remember Ben Is Obi-Wan
Throughout her encounters with Kenobi in the series, he refers to himself as Ben. The most straightforward explanation would be that Leia knows the person who rescued her is Ben, and never connected the dots that Ben is actually Obi-Wan.
He once stood in the middle of the Jedi Council, and not a single Jedi Master (including Yoda) could sense the dark side in him. Moreover, he also used a technique known as “Sever Force,” to dampen the Force abilities of every single Jedi in the galaxy, with little to no effort as well.
Yoda was a legendary member of the Jedi Council as a Grand Master of the Jedi Order and member of a mysterious species capable of living for centuries. He was stronger than most in a connection to the Force and though he was small in size, he'd been so powerful and wise having had trained Jedi for several centuries.
After their battle in Star Wars: Revenge of the Sith, Palpatine was sure Yoda was still alive. So why did he never bother finding the old Jedi master? While everyone remembers Anakin's fight against Obi-Wan, the battle between Yoda and Palpatine was just as important.
Is Grogu Yoda? According to the events of "The Mandalorian" so far, Grogu and Yoda are not the same character. They are simply from the same species. The name of this species has never been revealed since "Star Wars" creator George Lucas wanted to give Yoda a sense of mystery.
As such, it's very unlikely he will ever become one with the Force — at least not anytime soon. While it seemed Star Wars had “removed” Grogu/Baby Yoda/the Child in The Mandalorian Season 2, he returned in The Book of Boba Fett (2021) the following year.
The second time Yoda mentions his long life is in Return of the Jedi, when he tells Luke, “When you reach 900 years old, you will not look as good as you will.” If we take Yoda at his word, that means the Jedi Master died at the ripe old age of 900.
Grogu survived the Great Jedi Purge and was hidden away. Grogu was rediscovered by a remnant of the Galactic Empire after it fell, and became known to many simply as "The Child," during the New Republic Era. However Grogu was rescued by Din Djarin, a Mandalorian bounty hunter where he became a foundling.
As previously mentioned, Ben Solo was born in the early days of the New Republic and is very much alive by the time The Mandalorian kicks off.
Grogu's force sensitivity is the strongest reason that there is a bounty on him. While force sensitivity is the most important trait that he is being hunted down for, the imperial remnant might be seeking him to study the genetic traits, for cloning, or for training him to become one of them.
During the iconic opening moments of Star Wars: A New Hope, Darth Vader has a tense confrontation with Princess Leia, an adversary who, unknown to him, is actually his daughter. Despite participating in Leia's interrogation, the Sith Lord doesn't uncover his familial connection with the rebellious royal.
Because R2-D2 did not know. The last time R2 saw Anakin was when he accompanied Padme and Obi-Wan to Mustafar; while Anakin and Obi-Wan fought, R2 and C-3PO loaded Padme onto the ship, then saw Obi-Wan return alone, upset, and holding Anakin's lightsaber.
Fans have been dying for her to meet Luke on-screen for a long time, ever since their knowledge of each other was teased in the Star Wars book The Secrets of the Jedi. Here, it's hinted that Ahsoka inspired Luke to achieve greatness, with Luke himself mentioning that Ahsoka was his father Anakin's Padawan.
