For Merlin, there are both good and bad consequences. On the bad side, some of the more traditional and anti - magic people in Camelot might try to oppose him. However, since Arthur now knows, he has a powerful ally. Arthur can protect Merlin from those who would do him harm. Also, Merlin can now be more open about using his magic for the good of Camelot, which is a positive change.
I'm not sure if 'his wife is story' is a correct expression. It might be a misprint or an unclear statement. If you mean 'his wife is a storyteller', then it means his wife likes to tell stories. If it's something else, more context is needed.
Some of his other friends might react differently too. Some may be more cautious around him, worried about the power of the jinchuuriki within him. But those who truly trust Naruto, like Shikamaru, might not change their attitude much. They would see that Naruto is still the same person he was before, just with this added aspect to his identity.
His confidence would probably soar. Knowing he has his parents, who are likely strong ninjas, supporting him would make him feel more secure. He might become a bit less reckless as he now has people who care about him deeply and he wouldn't want to worry them.
His friends might be shocked too. They could be supportive of Harry, trying to help him come to terms with this new information. For example, Hermione would probably start researching if there was any way to change this in the magical world's past, while Ron would be more about just being there for Harry, sharing his feelings.
This revelation would likely shatter Harry's previous idealized view of his father. He might start to question all the stories he had been told. For example, if he was told his father was a hero, now he has to grapple with the fact that he was a bully. It could make Harry feel conflicted, angry, or even a bit lost. He may wonder if he has any of those bullying tendencies in him too.
Well, in this fanfiction scenario, if Naruto discovers Tsunade is his mother, it could change his entire world view. He has always seen Tsunade as a strong and somewhat intimidating figure in the village. Now, as his mother, she could become a more nurturing presence. Naruto might also start to question his own identity more deeply. He's used to being the orphaned Naruto, but now he has a family connection to one of the most powerful people in the village. This could lead to new storylines about him learning more about his family history and what it means to be related to Tsunade.
Nick would likely be very concerned. He might become more protective of Judy, not wanting her to put herself in dangerous situations again. He could also be angry at the circumstances that led to her getting hurt.
The expression 'he finds out his wife is story' is not a common one. But if we assume it means he discovers some aspect of his wife that is like a story, he might feel shocked at first. However, he should give his wife the chance to explain. For example, if she has a past relationship that she never told him about and it's now out in the open, he should consider that it was her past and focus on how they can move forward in their current relationship. He could also think about how this new discovery can add depth to their understanding of each other.
Well, first of all, he should sit down and have a good talk with her. Ask her about her stories, whether they are just for fun or if she has deeper intentions. If he is open - minded, he can join in on her storytelling. For example, he could help her create new stories by providing new ideas or different perspectives. This way, they can bond over her storytelling hobby.
