The run with Obi-Wan gave her an idea of what the situation was on the ground with Darth Sidious at the helm.
For years, there's been debate about whether or not she got lucky because she was adopted by Bail and Breha Organa and eventually became the princess of Alderaan. On the heels of the Obi-Wan Kenobi finale, Lucasfilm gives the public a new perspective on this, as it makes it look like the twins got the better deal. Spending time with people who died for the cause made her realize that she cannot sit on the sidelines. While Obi-Wan Kenobi focused on the Jedi Master's struggles to survive and keep his faith during the dark period of his life, the show also featured 10-year-olds. At the end of Star Wars: The Last Jedi, he sacrificed himself for the Resistance because of his traumatic experience in rebuilding the Jedi Order.
Lucasfilm was able to craft a story that sticks to the space opera's known canon because there was barely anything known about this particular point before Obi-Wan Kenobi.
While the Skywalker twins had vastly different upbringings as seen in Obi-Wan Kenobi, both eventually committed themselves to destroying the Galactic Empire and the First Order. She gave up her life in order to reach out to Kylo Ren in order to bring back Ben Solo. New details of Obi-Wan's life after the fall of the Galactic Republic were revealed in Lucasfilm's third Disney+ series. Even though he met Obi-Wan in the Obi-Wan Kenobi finale, he was spared the gory details that would have ruined his childhood. She used her position to help smaller pockets of the Rebellion until it was ready to be seen in the original Star Wars film.
The Star Wars origins story has been completely changed after the events of Obi-Wan Kenobi. Obi-Wan is disconnected from the Force a decade after Order 66. His life was drama- and danger-free because he had to work hard for money. He was mostly oblivious to all of this growing up. His attempt to rescue her leads to a number of near-death encounters, including two duels with Darth Vader. As part of Obi-Wan's story, he was almost killed by Reva. She was kidnapped a couple of times in Star Wars because she was in constant danger. He had no idea how bad the Empire was when he was introduced in A New Hope. At a young age, she couldn't simply be a child, she had to take on many responsibilities as a public figure. He was able to live away from the public's attention.
The first season of Obi-Wan Kenobi can be watched on Disney+. He wanted to get out of Tatooine for himself. He was forced to risk his life after Princess Leia was kidnapped.
