Dumbledore could also be an ally in the background. He may not be directly involved in the day - to - day care of the dragons, but he could provide Hermione with the necessary permissions and protection. His vast knowledge of magic and his influence in the wizarding world could help Hermione avoid getting into too much trouble for her dragon - caring activities. Additionally, some of the older and more experienced wizards in the Care of Magical Creatures department at Hogwarts might offer their assistance, albeit secretly.
Neville could be an ally too. His skills in herbology could come in handy when it comes to finding the right plants to feed the dragons or to use for medicinal purposes. Also, Luna Lovegood might be involved. Her unique perspective and knowledge of strange magical creatures could give Hermione new ideas on how to care for the dragons. She might know of some obscure spells or methods that are beneficial.
Harry and Ron could be her main allies. They've always been by her side in the original story, so it's likely they'd support her new adventure as a dragon rider. They could help her keep her dragon - riding activities a secret from the teachers at Hogwarts.
Harry and Ron would be her most likely allies. They are her best friends, and even if they might be initially shocked or jealous of her being in the tournament, they would surely come around to support her. Another likely ally could be Cedric Diggory. He's a fair - minded and kind wizard, and he might see Hermione's intelligence and skills as an asset and offer to help or at least be friendly towards her.
Perhaps Hermione gets involved in a dragon - breeding project gone wrong. She has to care for dragons that have some genetic mutations due to improper breeding. This could lead to her researching ancient dragon - care spells and potions. Or, she could be in a situation where she has to teach dragons how to fend for themselves in a changing magical environment, which would involve creating special training regimens.
Harry and Ron would most likely be her allies. They've always been by her side through thick and thin. Neville could also be an ally as he has shown courage and a willingness to stand up for what's right. Luna might be another one. Her unique perspective on things could be really helpful in a rebellion.
Harry and Ron could be her obvious allies. They've been through so much together, and if Hermione has a reason to get revenge on the Order, they'd likely stand by her side. They trust her judgment and would be willing to help her out.
Dumbledore could also be an ally. He is very knowledgeable and might give Hermione some advice or information about the vanishing cabinet that she needs to successfully sabotage it. He might also provide some protection if there are any risks associated with her actions.
One possible reason could be a misunderstanding. Maybe her friends thought she was following but she got distracted by something, like a new spell she saw in an old book. So they unknowingly left her behind.
A magical creature like a talking fox could be her ally. The fox might be immune to her frozen touch and understand her loneliness. It could help her navigate through dangerous forests or find hidden places where she can learn more about her power.
Another possibility is Harry Potter himself. This would be a very different take on their relationship. In some fanfiction, the strong bond between Hermione and Harry could be taken to a new level. Maybe in a situation where they are the last hope for the wizarding world, they conceive a child in secret to carry on some special magic or power that could save the wizarding community.
Sakura could be one of her main allies. Even in a samurai - themed story, Sakura's medical skills and combat abilities would be useful. She could support fem Naruto in battles and help heal any wounds.
