Fleur might expose them. If they are students, they could face expulsion from Hogwarts.

Well, Fleur is a complex character. When she finds out about Harry's abuse, she might initially be in disbelief. But once it sinks in, she would feel a deep sense of sympathy. Fleur might use her own experiences to relate to Harry. For example, she has faced prejudice in the wizarding world due to her Veela heritage. She could draw on that strength and determination to help Harry. She may offer him a place to stay away from his abusers, and use her magic to create a safe and comfortable environment for him. Also, she could start training Harry in some defensive magic so that he can protect himself in the future.

They might be shocked and immediately want to protect Harry. For example, they could confront the abuser or find a safe place for Harry.

And the school itself could start providing special resources for Harry, such as counseling or extra protection spells. Also, there could be a big change in the way the wizarding community views Harry. Instead of just seeing him as the 'Boy Who Lived', they would see him as a victim who needs support.

The other students could have a range of reactions. Some might be sympathetic and try to befriend Harry more. Others might be afraid, especially if the abuser is still around. But overall, it would create a stir in the wizarding community, and there would be a general outpouring of concern for Harry's well - being.

The abuser might face the wrath of the DA. They could be ostracized within the wizarding community. The DA members could use their influence to make sure the abuser is held accountable for their actions.

Their friendship would become deeper. Ron would be more protective and more attuned to Harry's emotions. There would be a new level of trust as Harry has shared such a difficult and personal experience with Ron.
