Their relationship could develop further through shared battles. As they fight side by side against the Empire, they learn to trust each other even more. Each battle they survive together deepens their bond.
They might start to open up more about their past traumas. For example, Rex could talk about the Clone Wars and how it affected him, and Ahsoka could share her experiences with Anakin. This mutual sharing would bring them closer together, understanding each other on a deeper level.
Their relationship could develop as they train together. Ezra would learn more refined Jedi techniques from Ahsoka. This would create a deeper bond of respect and mentorship.
One way to further explore their relationship is through the Force. Since they are both strong in the Force, they could sense each other's emotions and intentions from a distance. For example, Vader might feel Ahsoka's determination to stop him, and it could remind him of her as a young Padawan. Also, a story could be written where they communicate through the Force without actually meeting, sharing memories and feelings about their past together.
One common theme is loyalty. Rex and Ahsoka have a deep loyalty to each other that dates back to the Clone Wars. In many fanfictions, this loyalty is tested but always prevails. For example, in stories where they are faced with difficult choices that could put the other in danger.
In fanfiction, Rex's character often develops from a battle - hardened clone to a more empathetic and wise figure. He learns to trust his new allies in the Rebels, like Ezra and Kanan. His past experiences in the Clone Wars shape his decisions in the Rebellion, making him more cautious yet determined.
For Ahsoka, her character could be developed further by exploring her feelings of being an ex - Jedi. She could struggle with her place in the galaxy now that she's no longer part of the Jedi Order. Rex, on the other hand, could be developed by showing his life after the Clone Wars. Maybe he has a hard time adjusting to a new way of life without the structure of the military.
Perhaps they find themselves in a situation where they have to deal with a new Sith - like threat. This new enemy has a connection to their past in the Clone Wars. Ahsoka and Rex must figure out the nature of this threat and stop it before it spreads chaos across the galaxy. They could face many challenges along the way, like old clones who have been corrupted by the new enemy's dark influence.
One great 'Star Wars Rebels Rex and Ahsoka fanfiction' is 'Reunion on Lothal'. It beautifully captures their reunion after so long apart. The story delves deep into their shared history and how they've both changed since the Clone Wars. It has some really intense action scenes where they fight side by side against the Empire, and also some touching moments of reminiscing about the old days with Anakin.
The relationship could start as a mentorship. Shaak Ti, being an experienced Jedi, could initially see Ahsoka as a young, promising Jedi in need of guidance. Ahsoka, in turn, would respect Shaak Ti's wisdom and skills. As they go on missions together, they would grow to trust each other more deeply, like comrades in arms.
In some fan - made stories, their relationship develops through shared adventures. They might go on a quest to find a lost Jedi artifact. Along the way, they face many challenges and in the process, they start to trust each other more deeply. Anakin might learn from Ahsoka's more independent thinking and Ahsoka could gain a new respect for Anakin's skills.
In fanfiction, Ahsoka's character can develop by facing new challenges. For instance, she may have to deal with the moral gray areas that come with fighting in a Rebellion. This forces her to reevaluate her Jedi teachings and grow as a person.
