One possible 'Ginny punches Harry' fanfiction could be one where there's a huge misunderstanding between them. Maybe Harry accidentally reveals a secret that Ginny had trusted him with, and in her anger, she punches him. It could then lead to a series of events where they have to work through their issues and regain their trust in each other.
On the other hand, Ginny might secretly be a bit flattered that Harry is so possessive over her. But still, she would probably try to stop the situation from getting worse and make Harry understand that he can't just go around punching people because of her.
One possible reason could be Harry's deep - seated feelings for Ginny. If he has been secretly in love with her, seeing Ginny with Dean might trigger his jealousy and lead to such an extreme reaction like punching Dean.
There could be a 'Harry punches Ron' fanfic to explore different character interpretations. Maybe the writer wants to show a more impulsive and hot - headed Harry, or a Ron who has done something really wrong that would push Harry to such an extreme. It can also be a way to break away from the typical, harmonious view of their relationship and see how they would deal with such a violent rupture in their friendship.
Ginny might support Harry by simply being there for him. In the face of everyone else turning their backs, her presence can be a great comfort. For example, she could sit with him at meals when no one else will.
One possible reason could be miscommunication. Maybe Ginny feels neglected by Harry because he's so caught up in his own heroic deeds and doesn't pay enough attention to her. So she might seek comfort or excitement elsewhere.
It could severely strain their relationship at first. Snape might become even more bitter towards Harry, seeing this as just another sign of his lack of respect. Harry, on the other hand, might feel a bit of guilt but also a sense of righteousness if he thought Snape deserved it. However, over time, this incident could also be a turning point. It might force them to communicate more directly, which could lead to a more complex and nuanced relationship, whether it becomes more positive or remains hostile but with a new understanding.
There could be many interesting fanfictions on this topic. One idea could be that in this fanfiction, the 'force' might be some sort of magical or emotional force that binds Harry and Ginny even closer during her pregnancy. It could explore how they deal with the impending arrival of their baby while also facing challenges related to this special force.
Ginny might initially be heartbroken. She could retreat into herself, feeling betrayed and confused. In some fanfictions, she may cut off all contact with Harry immediately.
