Well, Female Obi - Wan could bring a different perspective to the training of Anakin and Ahsoka. She may focus more on their personal growth and well - being rather than just their combat skills. Anakin, under her guidance, might develop a better sense of self - control. His relationship with Ahsoka could also be more of an equal partnership rather than a master - apprentice one. Ahsoka, in turn, would be exposed to a different type of Jedi teaching, which could make her more versatile in her use of the Force and in handling different situations.
Female Obi - Wan might develop a more nurturing side. Instead of the more stoic Obi - Wan we know, she could be more openly affectionate towards Anakin and Ahsoka. Anakin, with this different influence, might not be as quick to turn to the dark side. He would have more emotional support. Ahsoka would grow to be more confident, as she has two strong role models in Female Obi - Wan and Anakin. She would be able to learn from their different styles of using the Force.
The presence of a child would likely make their relationships more nurturing. Female Obi - Wan might take on a more motherly role towards the child, and Anakin and Ahsoka would be influenced by her example. They would become more protective of each other as they are all responsible for the child's well - being.
One interesting storyline could be that Female Obi - Wan takes on a more maternal role towards Anakin and Ahsoka. She could be the one to help Anakin better control his emotions, which was a struggle in the original story. For Ahsoka, she could train her in a different way, perhaps focusing more on the spiritual side of the Force. This would change the dynamics of their relationships and lead to new adventures where they work together more harmoniously as a family unit.
To develop Anakin's character, start with his disillusionment with the Jedi. He believes they have failed him, so his turn to the dark side seems like a way to gain the power he thinks he needs. In the Mustafar part of the fanfic, he can be shown as more impulsive and less in control of his emotions. Obi - Wan, on the other hand, can be developed as a character who is still holding onto hope that Anakin can be redeemed, but is also ready to do what is necessary to protect the galaxy.
If Obi - Wan travels back in time, his character would become more self - aware. He would have the knowledge of his past mistakes and would be more cautious. For example, in his relationship with Anakin, he might be more empathetic from the start, understanding Anakin's insecurities better. This would lead to a different dynamic between them, and perhaps Anakin would not be so easily swayed by the Dark Side. Also, Obi - Wan would be more confident in his Jedi abilities as he has already seen the heights and lows of the Jedi Order in his own time.
One possible storyline could be that the female Obi - Wan discovers a lost child during a mission. Anakin and Ahsoka then help her take care of the child. They face many challenges like protecting the child from the Sith. As they do this, they also learn important lessons about family and loyalty.
Anakin might develop more self - control earlier. Yoda's wisdom and unique training style could help him better understand his emotions and not be so easily swayed by fear, which was a major factor in his fall to the dark side in the original story.
Some writers portray their relationship as more brotherly, with lots of friendly banter and deep emotional support for each other. They might show Obi - Wan as a protective older brother figure to Anakin. Other writers may focus on the master - apprentice aspect more strictly, highlighting Obi - Wan's role as a teacher and Anakin's as a student who is sometimes rebellious.
Padmé would be devastated. She loved both Anakin and Obi - Wan. Her relationship with Anakin would become extremely strained, if not completely broken. She might try to stop Anakin from further falling into the dark side or, in her grief, turn against him.
Maybe the Force itself could be an antagonist in a sense. The light side of the Force would be trying to pull Obi - Wan back from the dark side. And the natural balance of the Force that doesn't want too much dark side influence could be working against Anakin's plan to turn Obi - Wan. So the Force, in its own way, could be the main antagonist.
Perhaps Obi - Wan uses his Jedi skills in a creative way. For example, he could use a Force - related technique that shields Anakin from the influence of the Sith. He might create a sort of Force barrier around Anakin's mind, preventing the dark whispers from corrupting him further.
