As they face more and more threats from the Empire and the dark side, they would become more interdependent. Ahsoka might start to see Ezra as a true Jedi in the making, not just a young Padawan. Ezra, on the other hand, would look up to Ahsoka even more. They could also have some light - hearted moments during their travels, like joking about the strange aliens they meet or the clumsy droids they come across. These shared experiences, both in battle and in downtime, would cause their relationship to grow into a strong and unbreakable one.
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.
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.
Their relationship could start with mutual respect due to their Jedi training. As they go on adventures together, they'd grow to trust each other more. For example, in a fight against the Empire, Ezra might save Ahsoka's life, deepening their bond.
As they work together more often, they might develop a friendship. For example, Ezra could teach Leia some of the more unorthodox ways of using the Force that he learned from Kanan, and Leia could introduce Ezra to the broader political landscape of the Rebellion. This exchange of knowledge would bring them closer.
Ezra could be developed further by exploring his darker side. Maybe in a fanfiction, he gets tempted by a powerful Sith artifact and has to struggle with the pull of the dark side. Ahsoka, on the other hand, could be developed by showing more of her post - Jedi life emotions. For example, her feelings about the Jedi Order now that she has left it. They could also be developed through their interactions with each other. Ezra could learn from Ahsoka's more refined Jedi skills and Ahsoka could be inspired by Ezra's raw, unorthodox use of the Force.
Well, in a fanfiction where Ezra is trained by Ahsoka, it might start with Ahsoka recognizing Ezra's potential. Maybe she sees his raw talent with the Force and decides to take him under her wing. This training could lead to Ezra having a different perspective on the Force, perhaps more in line with Ahsoka's own beliefs which were shaped by her experiences with Anakin. It could also change the way he approaches battles and his role within the Rebellion.
Another possibility is that in the alternate universe, Chopper is actually a super - advanced droid with a hidden ability to enhance Ezra's Force powers. As they discover this ability, their relationship would shift from a normal friendship to a very special and powerful partnership. Ezra would need to keep Chopper safe not only because he's his friend but also because Chopper is key to his growth in the Force. This would lead to a much more intense and interdependent relationship.
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.
In many fanfictions, the relationship between Ezra and Maul is a slow - burn one. At first, Ezra is afraid of Maul, given his reputation as a dangerous Sith. But as Ezra matures in the Force, he begins to understand Maul's motives better. Maul, on the other hand, starts to see Ezra as a kindred spirit in a way, as they both are somewhat outcasts in the grand scheme of the Force - users. This mutual understanding leads to a relationship that is full of tension but also has elements of cooperation and even a strange sort of friendship.
Their relationship could develop in a hostile way at first. The Inquisitor is tasked with hunting Ezra, so he would be constantly on Ezra's tail, trying to capture or kill him. Ezra, in turn, would see the Inquisitor as a major threat and fight back with all his might.
Their relationship often develops through shared battles. As they fight side by side, they start to trust each other more. This trust then turns into a deeper connection.
