She might be overjoyed. After all, she's been separated from them for so long. She could immediately embrace them, tears of happiness in her eyes, and start telling them how much she has missed them over the years.
In this fanfiction scenario, she could initially be in shock. She might have thought she would never see them again. Once the shock wears off, she would be eager to get to know them. She would be curious about their personalities, their skills, and their dreams. And she would also feel a sense of responsibility towards them, wanting to make up for the lost time and protect them from any harm.
How about a spaceship? Perhaps their mother is on a journey of her own, and by chance, their paths cross in the vastness of space. The confined space of the ship would create an intimate setting for their meeting, and they would have to deal with the limited resources and potential dangers while getting to know each other.
Luke might be in awe. He's always been seeking his family and a sense of belonging, so meeting his parents could make him feel complete. He'd probably listen intently to whatever they have to say.
Luke would probably be excited. He's always eager to learn more about the Jedi. Leia might be a bit skeptical at first. Ahsoka would likely be analytical.
In fanfiction, when Luke and Leia meet their parents, it could be a very emotional moment. Maybe they finally understand their family's past and heritage better. They might learn secrets that were long hidden. Their parents could offer them wisdom and guidance that they've been lacking.
They would probably be very surprised at first. After all, they might not have expected to ever meet Luffy's mother. Then they would be excited to learn more about Luffy's past from her.
Often, Palpatine can still be a main antagonist even in time travel fanfiction. If Luke and Leia travel back in time, he might sense their presence and try to stop them from changing things that would undermine his power. Another could be Darth Vader if they travel to a time when he was still firmly on the dark side. He would be a powerful foe for them to face.
Perhaps it's a time - travel scenario in the fanfiction. Luke and Leia, having discovered a way to travel back in time, meet their parents. Anakin would be shocked to see his grown - up children, and Padme would be in awe of the strong Jedi and princess they have become. They could exchange stories of their lives, with Luke and Leia learning about their parents' early days.
One possible scenario is that they travel to a planet where they believe their parents' spirits reside. They might face various challenges on their journey, like hostile creatures or difficult terrains. Along the way, they could discover more about their family's history through ancient artifacts or wise beings.
The relationship would likely be more sibling - like from the start. In the original story, they didn't know they were siblings for a long time. But in this fanfiction, they'd grow up with that knowledge. So, they'd be more protective of each other right away and have a deeper understanding of each other's quirks and abilities.
I really liked 'The Time - Traveling Skywalkers'. It's a story where all four characters are caught in a time - travel anomaly. They end up in different points in time relative to each other. Padme gets to see a future where her children have grown up strong despite all the hardships. Anakin has to face his past self and tries to guide him away from the dark side. Luke and Leia use their knowledge of the future to try and make the galaxy a better place in the past. It's a really engaging read.
