Well, Sirius could be extremely protective of Hermione. Since he lost so many people he cared about, he doesn't want to lose her too. He stays by her side constantly, using his magic to ease her pain. As she recovers, Hermione starts to ask Sirius about his past, like his time at Hogwarts and his relationship with James Potter. This leads to a series of flashbacks that add depth to the story.
It's possible that Sirius finds a strange magical mark on Hermione when she's injured. This mark could be related to some new dark magic that Voldemort is using. Sirius then embarks on a journey to find out what the mark means and how to remove it, all while protecting Hermione from further harm. Along the journey, they encounter old enemies and make new allies, and Hermione's intelligence and Sirius's experience combine to solve the mystery.
Next, Sirius might immediately send for help from other members of the Order of the Phoenix. He knows that Hermione's knowledge and skills are crucial for the fight against the Dark Arts, so he wants to ensure she gets the best care.
One idea could be that Sirius uses his knowledge of magic from his time as an Animagus and as a member of the Order to quickly heal Hermione's injury. Maybe he transforms into his dog form to track down any threats still lurking around her.
There are many possibilities. Maybe Ash discovers that Drati's injury is part of a larger conspiracy. Or, it could bring Ash and Drati closer together as they go through this ordeal.
He might explore the spaceship out of curiosity. Naruto is always eager to learn new things, so he'd be all over the controls and strange gadgets inside. He could accidentally activate something that sends out a signal, attracting either help or danger.
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.
The baby might have some special powers that start to show up. Yami Yugi has to figure out how to control and help the baby develop these powers in a positive way. For example, if the baby can create portals, Yami Yugi will need to teach it when and where it's appropriate to use such a power.
Well, in many such fanfictions, Naruto might take the fox kit under his wing. He could start by trying to find out if the kit is injured or lost. Maybe he'd use his own experiences of being an outcast to empathize with the little fox. He might try to protect it from any harm in the village, as the villagers often misunderstand things related to foxes due to the Nine - Tailed Fox incident. And who knows, the fox kit could turn out to have some special powers or a connection to Naruto's own chakra.
She might be taken to a medical bay. The clones would surely be very grateful and protective of her. They would do everything they can to ensure her safety while she recovers. Maybe some of the clones would even offer to stay by her side as guards until she's fully healed.
Sirius would probably be very concerned. He might immediately ask her what's wrong and offer her a handkerchief to dry her tears. He has a bit of a wild side, but he also has a big heart, especially when it comes to those he cares about or sees as in need of help.
In the fanfiction, Loki could take Peter under his wing. He has a lot of power and knowledge, so he might train Peter to be more confident and able to defend himself. Loki might also use his magic to make Peter invisible when the bullies are around, so Peter can avoid them until he's ready to face them. And Loki would definitely give those bullies a stern warning in his own menacing way.
It could be that she's homesick. Even though she loves being at Hogwarts, sometimes she might miss her muggle family a great deal. Also, she might be crying because she's being bullied. There could be some students who are jealous of her intelligence and are giving her a hard time. In the fanfiction, Sirius finding her crying might lead to him becoming a sort of mentor or protector for her, helping her deal with whatever is making her sad.
