harry discovers draco is imperioues fanfiction

Well, in many such fanfictions, Harry might be shocked at first. He probably feels a sense of pity for Draco too. After all, being under the Imperius Curse means Draco has no control over his actions.

In the fanfiction, if Harry discovers Draco is imperioused, he might first be shocked. Then he would probably try to find a way to break the imperius curse. He could seek help from the teachers at Hogwarts, like Professor Snape or Professor Flitwick, who are knowledgeable about dark magic and counter - curses.

Perhaps Voldemort himself. He might see Draco as a tool, and Imperiusing him would allow Voldemort to have more control over the Slytherin side of Hogwarts or use Draco to spy on Harry. Another possibility is a rogue wizard who has a grudge against the Malfoy family and wants to cause them trouble by making Draco do things he wouldn't normally do while under the Imperius Curse.

Well, in this type of fanfiction, a plot point could be the change in Draco's behavior. Since he is under the Imperious Curse, his actions might seem out of character. Harry might notice that Draco is doing things that he wouldn't normally do. For example, Draco might be acting more subservient or being forced to target Harry in a more malicious way than before. This would make Harry start to suspect something is wrong. Also, there could be a plot point where Harry has to convince his friends, like Hermione and Ron, that Draco is not acting of his own free will. They might be skeptical at first, but as Harry uncovers more evidence, they come around to help him figure out how to break the curse on Draco.

The plot could involve Harry suspecting the Death Eaters or some other dark forces of being behind the Imperius Curse on Draco. So, he starts to investigate secretly, which might lead him into dangerous situations. Maybe he discovers a connection between Draco's Imperius state and a larger, more sinister plot against Hogwarts or the wizarding world in general.
