Adrien would probably feel a mix of emotions. He'd likely be nervous as he approaches the prison, not knowing what to expect. Once he sees his father, there could be a sense of sadness, especially if his father looks different or broken. He might also feel anger, thinking about all the wrongs his father has committed that led to this situation.
Adrien would probably feel a mix of emotions. He'd likely be angry at his father for the wrongdoings that landed him in prison. But at the same time, he might also feel sad because it's still his father.
Plagg would also be there. Plagg is Chat Noir's kwami, and he has a special bond with Adrien. He would probably be worried about Adrien's condition and try to cheer him up in his own unique, mischievous way, like making cheesy jokes or trying to steal some cheese from the hospital cafeteria.
If Adrien were Hawkmoth in fanfic, it could change the dynamics of the story completely. It might explore his internal conflicts and the impact on his relationships with other characters.
Maybe a mysterious new character in the fanfiction. This character could be from Adrien's family's past, someone with a vendetta against his family, and decides to start by getting Adrien arrested to disrupt the family. For example, if Adrien's family wronged this character's family long ago, they see Adrien as a target to take revenge on the whole family.
It could be Ladybug. If Adrien turns villain, Ladybug would be the natural antagonist as she represents the good side. Their relationship would be completely flipped from what it was before. She would have to try to stop him from causing more harm, all while probably still having some feelings for the old Adrien.
Nathalie might be a character in these fanfictions too. Given her role in Adrien's life in the original series, she could be involved in the events leading up to his akumatization. Maybe she accidentally triggers his negative emotions. And then there's Gabriel, Adrien's father. His actions or lack of actions towards Adrien could be a major factor in Adrien getting akumatized. So, he could be a key character in the fanfiction, either as someone who realizes his mistake and tries to help or as someone who makes the situation worse.
Some cousin x cousin fanfiction might focus on family drama. The relationship between the cousins could be a catalyst for all sorts of family issues, like secrets being revealed or family members taking sides. For example, if the cousins' relationship becomes public, different family members might react in very different ways, which can be a really interesting plot point.

And then they were pronounced husband and wife, sharing a passionate kiss as confetti rained down on them.
