The impact would be minimal in the grand scheme of the wizarding world. Molly is just one person, and fanfiction is a rather niche concept. However, if she were to make a big deal out of it, it could cause some stir among those who are close to her. For example, Ron and Hermione themselves might be a bit embarrassed or amused if they found out that Molly knew about the fanfiction. And it could also make some of the older, more traditional wizards raise their eyebrows in confusion at this newfangled Muggle - inspired idea.
Well, it might also lead to a split in the wizarding community. Some might side with Ron and Hermione, believing they had a good reason to abandon Harry. Others would be outraged and try to find Harry and bring him back. This could create chaos and internal conflict within the wizarding world, making it vulnerable to outside threats as well.
Hermione's spell - casting skills would be very useful. For example, she could use the Stunning Spell to immobilize enemies quickly. Also, her knowledge of potions could potentially be used to create antidotes for any toxins or poisons the Avengers might encounter.
If Hermione can convince Dolohov to change his ways, it could have a huge impact. He might be able to provide valuable information about the dark side's plans, which could help the Order of the Phoenix. For example, he could reveal the location of hidden dark magic artifacts or the identities of undercover Death Eaters.
The baby's existence could also have a unifying effect. Given that Hermione is a Muggle - born and Ron is a pure - blood, their family represents a combination of different wizarding backgrounds. Their baby could be a symbol of unity, inspiring other wizards and witches to look beyond blood status differences and work together more harmoniously.
One possibility could be through some sort of time - traveling or alternate universe scenario in the fanfiction. Maybe a spell gone wrong sent Hermione back in time and through a series of complex events, she ended up in a situation where she was related to Draco in that way. It's a very creative and out - of - the - box concept that fanfiction often explores.
On the negative side, if some fanfiction contains misinformation or harmful ideas, she might have to be careful not to be influenced by them. However, if she's smart about it, she could use her study of fanfiction to bridge the gap between the official wizarding knowledge and the more creative, fan - based ideas. This could make her a sort of cultural ambassador between the two worlds, helping to bring new and exciting concepts into the mainstream wizarding society while also protecting it from the less desirable elements of fanfiction.
Hermione's friends, like Harry, would likely be very protective of her. They might try to keep the news from spreading too far and help Hermione in any way they can. As for Draco, his family's reaction could be complicated. They might see this as an opportunity to gain some sort of advantage over the Weasleys, or they might be more sympathetic to Hermione's situation depending on how Draco feels about her.
One way this could be possible is through a long - lost bloodline. Maybe Merlin had a child or a relative whose descendants remained hidden for centuries. And Hermione, being a very powerful witch, could be part of this secret line. In the wizarding world, there are many hidden families and secrets, so it's not entirely far - fetched.
Well, in fanfiction, anything can be possible. It could be possible through some dark magic or a complex time - travel plot. Maybe a spell went wrong and created a connection between Hermione and Tom Riddle that led to her being his daughter. However, in the original "Harry Potter" lore, it's completely against the nature of good and evil as Hermione is on the side of good and Tom Riddle is the evil Lord Voldemort.
She might be quite surprised at first. Fanfiction often takes the relationships of the characters in unexpected directions. Molly is a rather traditional character, so she could be a bit taken aback by some of the more creative interpretations in the fanfiction about Ron and Hermione.
