Often, Naruto would use his own experiences to comfort Hinata. He has faced so much rejection and loneliness in his life. So, he might share those stories with her, like how he was always the outcast in the village at first. He'd say something like 'I know how it feels to be alone, but look at me now. And you're so much stronger than I was, Hinata.'
Another way Naruto could comfort Hinata in fanfiction is by protecting her. When she's in danger or scared, Naruto would step in and shield her. Then he'd tell her not to be afraid because he'll always be there to keep her safe. He might also joke around a bit to lighten the mood, like 'You know I'm not going to let anything happen to you. I'm too stubborn for that!'
Often, Minato comforts Naruto through words of affirmation. He tells Naruto how proud he is of him. Since Naruto has been constantly seeking validation, especially from his family, Minato's positive words can be extremely comforting. Minato might also explain to Naruto the reasons behind some of the hardships he has faced, like being the Jinchuriki of the Nine - Tails. This can help Naruto better understand his situation and feel less burdened.
Well, first of all, the fanfiction usually establishes how Hinata gets brainwashed. It could be something as simple as a rogue ninja using a mind - control technique on her. After that, the story focuses on the consequences of her brainwashed state. For instance, she could be used to spy on the village or cause chaos. Naruto, being the main character, senses that something is wrong with Hinata. He then starts to dig deeper, using his skills and the help of his friends. The development often includes a lot of emotional turmoil for Naruto as he tries to save Hinata while also dealing with the potential danger she poses to the village. Eventually, the story reaches a resolution where Hinata is either freed from the brainwashing or there's a new development that keeps the story going.
Naruto might also become more cautious. He's always been a bit of a trusting person, but after Hinata's betrayal, he would be more careful about who he lets close. He would analyze his relationships more deeply and be on guard against future betrayals. This could change his approach to both his friendships and his role in the village as he tries to protect himself from further hurt.
Often, it portrays their relationship in a more intense and complex way. The hypnosis can act as a catalyst. For instance, if Hinata is hypnotized to be more assertive, she might take the lead in their relationship, which is different from her usual shy self.
In these fanfictions, at first, the relationship is often strained. With Naruto being evil, he may push Hinata away. But Hinata's love remains constant. As the story progresses, Naruto might start to see Hinata's efforts and slowly warm up to her again, gradually rebuilding their relationship.
These fanfictions usually change the storyline by introducing a new dynamic between Hinata and Naruto. With Hinata being evil, their relationship is no longer one of mutual support. For instance, Hinata might try to undermine Naruto's goals or turn his friends against him. This completely flips the original positive relationship they had in the anime. Also, it can create new alliances and rivalries as other characters react to Hinata's new persona.
One common theme is Hinata's understanding of Naruto's loneliness. Since Naruto has often been alone in his life, Hinata's presence to comfort him fills that void. For example, in many fics, she simply sits and listens to him talk about his problems.
In these fanfictions, their relationship development might also be shown through their shared experiences outside of the main ninja battles. For instance, they could volunteer together in the village to help rebuild something. During this time, they get to know each other on a deeper level, sharing their hopes and dreams. Naruto might discover Hinata's dreams for the future of the Hyuga clan and how she wants to make it more inclusive, and this makes him admire her even more. As they spend more time together, their relationship deepens, and they start to fall in love.
Well, it could be that Draco has a moment of realization at the Yule Ball. He notices Hermione is alone and sad, perhaps because Ron has been a jerk. Draco, having his own issues with expectations and family pressure, might feel a connection. So he approaches her and starts a conversation. He might say something like 'I know how it feels to be out of place sometimes.' This simple act of reaching out can be a form of comfort.
Often, he's portrayed as selfish. In these fanfictions, Sasuke may be shown as not caring about the consequences of his actions on others, especially Naruto and Hinata. He could be seen as a rival who is always trying to one - up Naruto in a negative way, rather than a healthy rival. And his actions might be painted as always causing trouble for Naruto and Hinata's relationship.
