Well, they could start by comparing their experiences with the Jedi Order. Ahsoka left the Order, while Luke was trying to rebuild it. This encounter could be a moment of reflection for both. Maybe Ahsoka would share her doubts and disillusionment with the old Order, and Luke could learn from her. They might also team up to search for ancient Jedi artifacts or lost knowledge, believing that together they could unlock secrets that neither could alone.
In this fanfiction, they might initially be cautious of each other. Luke, being a Jedi, would sense Ahsoka's strong connection to the Force. They could exchange stories about their experiences with the Jedi Order. Maybe Ahsoka would share her insights from the Clone Wars, and Luke could tell her about his journey to become a Jedi and defeat the Empire.
One plot point could be a Force - vision they share. In this vision, they see the future of the Jedi Order and their roles in it. This could lead them to make certain decisions to shape that future. Another could be that they encounter a new Sith threat together. Their different experiences with the Sith (Luke with Vader and the Emperor, Ahsoka with Dooku and Maul) would come into play as they strategize to defeat this new enemy.
If they trained together, Luke would learn a great deal from Ahsoka. She has a different style of combat and a unique understanding of the Force. Luke might pick up new lightsaber techniques that could enhance his own fighting ability.
One possible adventure in a fanfic could be Ahsoka and Luke teaming up to face a new Sith threat. Ahsoka's experience with the Clone Wars and her knowledge of the Force could combine with Luke's Jedi training. They might travel to a long - forgotten planet in search of an ancient Jedi artifact that could help in their fight against the dark side.
One idea could be a story where Anakin and Ahsoka are reunited after a long time apart. Maybe Anakin has been on a secret mission and Ahsoka has been exploring new parts of the galaxy. When they meet again, they have to work together to face a new threat that is endangering the Jedi Order.
In fanfiction, their training sessions were intense. Anakin would push Ahsoka to her limits. He'd teach her new lightsaber techniques, like advanced forms that require great speed and precision. For example, he might show her how to quickly transition between forms during combat.
Ahsoka, in fanfiction, is usually shown as a determined and quick - learning apprentice. She might be depicted as having a great respect for Anakin, and their interactions can highlight her growth as a character. For instance, she could learn important lessons about the Force and life in general from Anakin's experiences.
In fanfiction, if Ahsoka meets Luke Skywalker, they could potentially train together. Luke, having been trained by Yoda and Obi - Wan, could share his knowledge of the Force with Ahsoka. Ahsoka, with her years of experience in combat and her own understanding of the Force, could offer Luke new perspectives. They might go on adventures together, facing new threats to the galaxy.
They could develop a mentor - mentee relationship. Luke, having been trained by Obi - Wan and Yoda, could pass on some of his knowledge to Ahsoka. Or it could be the other way around, with Ahsoka sharing her combat skills and knowledge of the Clone Wars era with Luke.
