He might first try to calm the owl down. He could use a soft voice and gentle magic, like a simple soothing spell. Then he'd carefully examine the injury. If it was a broken wing, he'd try to splint it with a small stick and some cloth.
Harry could take the owl to the hospital wing at Hogwarts. Madam Pomfrey, although mainly focused on students, might take pity on the owl and treat it. She'd use her medical knowledge and magic to heal the owl's wounds. She might give it a special potion to ease the pain and speed up the healing process.
In some fanfictions, Harry might ask his friends for help. Ron, for instance, could offer some advice based on what he's seen his family do with their owls. Neville might know some plants that could be used to make a poultice for the owl's injury. Together, they'd all work towards helping the injured owl.
In some fanfictions, Harry might take the injured owl to Hagrid. Hagrid, being an expert with magical creatures, would then tend to the owl's wounds. He might use various potions and spells to heal it. For example, he could use a healing charm that he learned from his time at Hogwarts or some special herbs from his garden.
In this kind of fanfiction scenario, Snape might initially be conflicted. On one hand, he has his long - standing dislike for James Potter, Harry's father. But on the other, his sense of duty as a Hogwarts professor could kick in. He might reluctantly start to heal Harry, all the while muttering under his breath about how much trouble Harry always seems to get into, just like his father. Then, as he heals Harry, he might start to see some of Lily, Harry's mother, in him and soften a bit.
Harry could use his intelligence and the skills he's learned from his friends. He might outwit the bullies by setting up traps or cleverly avoiding them. For instance, he could use the Marauder's Map to know their whereabouts and stay clear.
The fanfiction might show Harry re - evaluating his relationships based on this new identity. He may wonder how his identity as a potential parent affects his relationships with Ginny or other love interests. His friends may also view him differently, and he has to figure out if he still fits into the same social circles or if he needs to find new ones.
Harry might be shocked at first. He'd probably feel a sense of urgency to break the Imperius Curse. He could also feel a bit of pity for Draco, as Draco is being controlled against his will.
Well, in some fanfictions, he might be healed by a powerful magical herb that is rarely found. Maybe a character like Hermione goes on a dangerous quest to find it. She uses her extensive knowledge of magic and ancient texts to track it down, and once she gets it, the herb has the power to mend Harry's severe injuries.
Often, Harry will offer her a handkerchief or a tissue if there is one available. He might also put his arm around her in a comforting gesture. In 'The Common Room Crisis' fanfic, he does just that and then stays with her, listening intently as she pours out her feelings. He is patient and understanding, which is in line with his character in the original books. He tries to make her laugh or at least smile by sharing a joke or a funny memory. This shows his deep friendship and care for Hermione.
Perhaps Harry tries to find the root cause of the rejection. He might start investigating if there's some sort of dark magic or false rumor spreading about him that has made everyone turn against him. He could question his closest friends or even seek out the help of some of the more reclusive teachers at Hogwarts to figure it out.
He might be shocked at first. It's not every day you find out you have mates. He could be a bit clumsy around them, not knowing how to act. Maybe he stutters when he tries to talk to them or gets all flustered.
When Harry is severely injured, he often becomes more vulnerable. This can make him more relatable. He might start to rely on his friends more, which deepens his relationships. For example, Hermione might use her vast knowledge to find a way to heal him, and this could strengthen their bond.
