Well, a big challenge might be dealing with the different loyalties. Harry is often associated with Dumbledore's side, while Draco's family has ties to the Death Eaters. Harry will have to navigate this complex web of loyalties. For example, if the Death Eaters find out that Harry is protecting Draco, they might target Harry more vigorously. And from Draco's perspective, he might be conflicted between his family's expectations and Harry's protection. Plus, in the wizarding world, rumors spread fast. Harry protecting Draco could start all kinds of wild rumors that could put both of them in an uncomfortable position.
Harry may face the challenge of trust. Draco has been a bully to Harry and his friends in the past. So, Harry has to overcome his own doubts about whether Draco is truly worth protecting or if he's just going to stab him in the back. There's also the challenge of physical protection. Draco might be involved in dangerous situations, like in the Forbidden Forest or during duels. Harry has to have the skills and resources to keep Draco safe in these scenarios. And don't forget about the social aspect. The wizarding society has certain expectations and norms, and Harry protecting Draco goes against the typical behavior between students of their two houses, which could lead to a lot of social pressure.
One of the main challenges could be the animosity between Gryffindor and Slytherin. Harry is a Gryffindor and Draco is a Slytherin, and their houses have a long - standing rivalry. So, other students from both houses might not understand why Harry is protecting Draco and could try to interfere. Another challenge could be Draco's own pride. He might not want to be seen as needing protection, especially from Harry, which could make it difficult for Harry to do his job. Also, there could be external threats, like dark wizards who target Draco for some reason, and Harry has to constantly be on guard against them.
Well, one challenge could be the public perception. Since Draco is a new reporter, he might be investigating something controversial. Harry has to protect him from those who don't want the truth to come out. Another challenge could be Draco's own pride. He might not want to be seen as needing protection, which could put him in more danger.
One challenge could be dealing with the other students' reactions. Most students at Hogwarts have pre - conceived notions about Harry, Hermione and Draco. For Harry and Hermione, Draco has always been seen as a bit of a bully. And for Draco, being friends with a Gryffindor like Harry and a Muggle - born like Hermione goes against his family's beliefs. So they'd have to face a lot of gossip and maybe even some hostility from their peers.
One challenge could be Harry's distrust. Harry has had a long - standing enmity with Snape, so he might be reluctant to accept Snape's help. Another is the complex nature of Harry's problems. Harry has faced so many traumas and has a big destiny to fulfill. Snape might find it difficult to address all these issues without overstepping boundaries or causing more harm.
Managing the bureaucracy within the Ministry is no easy feat. There are likely many long - established traditions and procedures that might be resistant to change. Harry, who might be more used to action - oriented tasks, will have to learn how to deal with the red tape and inefficiency that often comes with a large organization like the Ministry.
One reason could be that Harry has a newfound sense of fairness. He realizes that Draco is constantly hounded by over - eager girls and he doesn't think it's right. Harry has been through a lot himself and he might empathize with Draco not wanting to be bothered all the time.
One challenge could be getting Hermione to eat. Babies can be picky eaters, and in the wizarding world, there might be special potions or foods that Hermione needs but doesn't like. Another challenge is keeping her safe from magical accidents. With all the magic around, a simple spell could go wrong and put Hermione in danger.
One challenge could be dealing with other students who don't understand his over - protective attitude towards Harry. Some might think he's being too nosy or interfering. Another might be that he has his own studies and responsibilities at Hogwarts which could sometimes conflict with his protection duties.
One challenge could be the Time - Turner rules. If they are using a Time - Turner, they need to be very careful not to break any of the laws regarding time travel. For example, they can't be seen by their past selves or make significant changes that would disrupt the future they come from. Another challenge is the danger of the time period they visit. If they go to a time when Voldemort was active, they are at great risk of being detected by Death Eaters.
One challenge would be the goblins. They are very protective of Gringotts and would not easily give up control. They have their own laws and traditions regarding ownership. Harry would have to deal with their resistance and find a way to convince them or negotiate with them.
One challenge could be cultural differences. Harry is from a world where magic is more about spells and potions, while Zatanna's magic is more about incantations and showmanship. Another challenge might be the acceptance of their relationship by their respective communities. Some in the wizarding world might think Zatanna's magic is too different and unorthodox, and some in Zatanna's world might not understand the ways of the wizarding world. Also, they might face villains who target them because of their combined power and the threat they pose to the status quo.
