An AU fanfic is a type of fan fiction where the story takes place in an alternate universe with different settings or circumstances than the original work.
An au fanfic is a type of fan-written story that takes the characters or setting of an existing work and places them in an alternate universe or situation that differs from the original.
The development of their relationship in Harry and Umbridge lemon fanfiction can be quite diverse. It could be that Umbridge, in an attempt to control Harry more closely, gets drawn into his world in a way she didn't expect. Harry, on the other hand, might start to see through her tough exterior and find some vulnerability in her. This discovery could lead to a series of exchanges between them, some filled with tension, some with a strange sort of understanding, and over time, this shapes their relationship in the fanfiction.
Harry Potter would surely interact with her. Given their history of animosity, he would be one of the first to notice and oppose her new 'dark lady' ways. He would try to protect Hogwarts and his friends from her schemes.
Hermione might also try to turn the situation around to expose Umbridge's tyranny. She could gather evidence of Umbridge's improper behavior during the punishment process and then use it to convince the other teachers or even the headmaster that Umbridge is a bad influence in the school. This would be in line with her intelligent and problem - solving nature.
One way is to have an open and honest conversation with the host family during the interview process. Au pairs can ask about the family's expectations and also share their own. And during the stay, if something is wrong, don't be afraid to speak up or seek help from the au pair agency. Au pairs should also trust their instincts. If something seems off during the initial contact with the family, it might be a sign to look for another opportunity.
In the context of the original Harry Potter story, it seems quite abnormal as Umbridge is a very unlikable character to Harry. But in the world of fanfic, anything can happen. Fanfic allows for different interpretations and character developments, so while it's not normal in the traditional sense, it's possible within the creative space of fan - created stories.
