Well, it might start with Sirius yelling at Ron and Ron feeling really bad about it. Then, Ron might try to make amends by doing something brave or helpful. For example, he could volunteer for a dangerous mission to prove his worth and show Sirius that he can be trusted.
In some cases, the conflict could escalate further. Ron might get defensive and argue back with Sirius, which would only make Sirius angrier. This could create a rift in their relationship for a while until something major happens, like they are faced with a common enemy. Then they would have to put their differences aside and work together, gradually rebuilding their relationship.
It could be that Ron's actions were causing problems within the Order of the Phoenix. If Ron was being stubborn and not following the plans or orders set by the Order, which Sirius is a part of, Sirius might get angry. He would be frustrated with Ron for not being a team player and potentially endangering the mission and the lives of others.
He might become withdrawn at first. Since he's used to being in control and having a certain dynamic in their relationship, Bella's anger could shock him into pulling back. He could go off on his own for a while to think about what he did wrong.
Often, it starts with the shooting incident. Then, it may show the immediate aftermath, like Anakin being rushed to medical help or his comrades trying to protect him from further harm.
Typically, Vegeta's character growth is a big part of how their relationship progresses. As Bulma is pregnant, he begins to see the importance of the family he's creating. He might train less rigorously to be around more for Bulma. This new dynamic makes their relationship more complex and loving, with them depending on each other more and learning to compromise.
Some fanfictions might have Hermione immediately cut Ron out of her life. She's a strong - willed character, and such a hurtful comment could be the last straw. This would then lead to a story about her moving on without him and finding new friends or allies.
Often, it starts with the initial moment of Harry getting mad. Then Ginny tries to figure out why he's so angry. For example, she might approach him and ask directly, but Harry could be too stubborn to tell her right away.
Often, in such a fanfiction, the story develops around the chaos that his transformation brings. Since Inuyasha is now a child, his usual brash and confident self is replaced with a more innocent and sometimes naïve version. This can lead to some comical situations, like trying to fight with a smaller body and less strength. His friends have to keep him out of trouble more than before, and there could be a plot where they search for a way to turn him back to normal.
Well, it depends on how the writer wants to take it. If it's a more angsty fanfic, their relationship could be on the rocks for a long time. Ron's outburst might make Hermione question their friendship. But if it's a more light - hearted fanfic, they could quickly make up. For instance, Ron could accidentally trip over his own feet while trying to apologize to Hermione, which would make her laugh and forgive him right away. Their relationship could then continue with a bit more self - awareness on Ron's part about his temper.
Often, the betrayal is sudden. For example, if it's his friends who betray him, it might start with a small incident that Harry doesn't think much of at first. But then it snowballs into a full - blown situation where his friends turn their backs on him completely. Then Harry has to struggle to deal with this new situation while also facing other threats in the wizarding world.
Often, her friends or the Justice League members will come to her aid. They'll try to heal her and figure out who or what caused her harm. Then, they'll start planning a counter - attack or a way to prevent further harm. For example, if it was a new villain, they'll start researching the villain's weaknesses.
