One way could be through words of wisdom. Kakashi has a lot of life experience and could share his insights with Sasuke, like how to deal with his inner turmoil and the path he should choose. For example, he might tell Sasuke that revenge isn't always the answer and that there are other ways to find peace.
In a fanfiction, Sasuke could be kidnapped by a mysterious organization that is interested in his unique genetic makeup as an Uchiha. Kakashi would immediately start his investigation. He'd recall Sasuke's past enemies and possible motives. He might discover that the kidnappers are planning to extract Sasuke's chakra or use his body for some sort of experiment. Kakashi would then have to infiltrate their hideout, which could be filled with dangerous jutsu - based security measures.
Yes, there might be some fanfictions out there with such an unusual plot. However, it may not be a very common or mainstream concept in the fanfiction community. Fanfiction often explores creative and sometimes out - of - the - box ideas, and this would be one of them.
Kakashi would be deeply concerned. Given his relationship with Sasuke, he'd feel a strong sense of duty to save him. He'd use his extensive network of contacts within the ninja world to try and find out where Sasuke has been taken. He might also reflect on his past training with Sasuke and how he can use that knowledge to anticipate the kidnappers' moves. He'd be ready to face any danger or obstacle in his path to rescue Sasuke. And he'd be constantly thinking about Sasuke's safety and well - being during the whole process.
It would be very close. Kakashi would be like a father or an older brother to them. Naruto and Sasuke would respect and rely on him. They would probably have a more harmonious relationship with each other too, because Kakashi would be there to mediate any conflicts.
There could potentially be some really creative and out - of - the - box fanfictions with this concept. But finding one might be a challenge. You could try searching on specialized fanfiction websites and use specific search terms like 'Kakashi Sasuke non - traditional relationship fanfiction' and then look through the results to see if there are any that involve the idea of Sasuke being pregnant. But remember, this is a very unusual concept even for fanfiction.
One possible reason could be training. Maybe Kakashi's training methods are too harsh for Naruto. Naruto is eager to become stronger quickly, but Kakashi might be holding him back in Naruto's eyes. For example, Kakashi could be making Naruto do repetitive basic drills instead of teaching him more advanced jutsu right away.
Another possibility is a jealous rival. Maybe there's someone who is jealous of Gohan's power or his relationship with certain characters. This rival could do things to annoy Gohan and push him to the edge of his temper.
A new player on an opposing team could be the cause. This new player might be overly cocky and disrespectful towards Kuroko during a game. They could constantly taunt him about his lack of presence, which finally gets on Kuroko's nerves and makes him mad.
It could be Vegeta. Maybe Vegeta does something really underhanded like stealing Goku's senzu beans or trying to take all the credit for a victory that Goku also contributed to. Goku, being a fair - minded person, would get angry at such behavior.
