Hermione could face a lot of challenges. First, Draco might set very high standards for her that are difficult to meet, either because he wants to test her or because he still has some of that old rivalry in him. Second, there could be a lack of trust between them initially. Since they were not on good terms before, it might take time for Draco to fully trust Hermione with important tasks. Third, the workplace environment itself might be hostile. If other employees are aware of their past relationship, they might side with Draco or make Hermione's life difficult. Hermione will need to be very resilient and use her intelligence to overcome these challenges.
One challenge could be the different portrayals of Draco in fanfiction compared to the original. In the original series, Draco has a certain set of characteristics, but in fanfiction, he can be very different. Hermione would have to understand these new interpretations to translate accurately. Another issue might be the specific language and tone used in fanfiction, which can be quite different from formal writing.
One challenge could be finding a safe place to stay. The wizarding world is not that big, and there are many places that are easily detectable. They would need to use magic carefully to avoid leaving a trail for those who might be looking for them.
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.
Hermione would face numerous challenges. Firstly, the social aspect. The wizarding society is quite traditional and her relationship with Snape is far from the norm. She would be shunned by many. Secondly, there are the practical challenges. Raising a child is difficult, especially when the father - child relationship is so complicated. Snape's past and his cold demeanor could make it hard for him to be a warm father figure. Thirdly, Hermione would have to re - evaluate her own identity. She has always been seen as a smart, rule - following witch. This situation goes against that image. She would have to find a new sense of self in the midst of all the chaos and judgment.
Hermione would also face the challenge of secrecy. If the wrong people found out, it could put her in danger. And she might have to constantly lie to her friends and family, which would be really hard for someone as honest as her. In some fanfictions, this internal struggle is really well - explored.
She might face opposition from the traditional wizarding community. Since Hermione is often coming up with new and untested ideas, some conservative wizards might not accept her inventions. They might think that these new inventions go against the old - fashioned ways of magic and should not be allowed in Hogwarts or the wizarding society at large. For instance, if she invents a new form of magic transportation that is different from brooms or apparition, the old - school wizards might be against it.
One challenge could be the reaction of their families and friends. Hermione's friends might be skeptical of Pansy at first, given her past behavior. And Pansy's family might have different expectations for her. Another challenge could be the wizarding society's view. It's not common for two witches, especially ones from different social circles like Hermione (a Muggle - born hero) and Pansy (a former Slytherin with a less - than - stellar reputation), to get married.
One challenge could be his own reputation. Snape has a rather dark and brooding image at Hogwarts. So, other students or even some teachers might be suspicious of his motives for being Hermione's guardian. Also, Hermione is very independent - minded, which might clash with Snape's over - protective tendencies at times.
Hermione would face a great deal of prejudice from the pure - blood society. Since she is Muggle - born, many in the wizarding world, especially those in the Malfoy's social circle, would look down on her. She would also have to deal with Draco's own internalized prejudices. He has been taught to think of Muggle - borns as inferior, and Hermione would have to work hard to change his view. Another challenge would be maintaining her own identity. The Malfoy family has certain expectations and a way of life, and Hermione would have to find a way to be true to herself while also fitting into this new family dynamic.
She would face the challenge of dealing with Tom's own nature. Even as a baby, he might have some of the traits that later led to his dark side. Hermione would have to find ways to nurture his good side and suppress the bad. Also, she has her own life and studies. Balancing taking care of a baby and her own development would be difficult.
