A plot twist could also be that they run into some old enemies from Harry's past who have somehow found their way to La Push. These enemies could be after Teddy for some reason, like they think he has some special power that they can use. Harry then has to protect Teddy and the new home they've found in La Push.
Perhaps Teddy starts to have strange dreams about the forest in La Push. These dreams could be some kind of premonition or connection to an ancient power in the area. As they investigate, they find out that there's an old magic that is starting to reawaken, and they have to figure out how to deal with it before it causes chaos.
One possible plot twist could be that they discover a hidden magical community in La Push. Maybe it's a group of Native American wizards who have their own unique brand of magic that Harry and Teddy have never seen before. This could lead to all sorts of adventures as they try to understand and interact with this new group.
Well, they could get involved in the local werewolf lore. Since Teddy is a werewolf (as Tonks was his mother), La Push being a place full of werewolves in the Twilight universe (if this is a crossover), he might find a new community. Hermione, with her intelligence, could perhaps study the unique magic or phenomena in La Push. Maybe they'd make new friends, or even face some threats that are specific to the area.
Well, a plot twist might be related to their families. What if Harry's fame starts to cause problems in their new neighborhood? Some people might be too curious or intrusive. Also, Ginny could get an unexpected job offer in a far - off place, and they have to decide whether to stay in their new home or move again. And it could be that there's a magical creature living in their attic that they didn't know about at first, and it causes chaos in their new living situation.
Well, it could be about Bella exploring the new place in La Push. Maybe she makes new friends there, discovers local secrets, and has some adventures in the unique setting of La Push.
Well, if they arrive, it could cause a bit of a stir. Harry is quite famous in the wizarding world. Some in the local community might be curious about him and his powers. At the same time, Teddy's unique abilities as a metamorphmagus could be both fascinating and a bit intimidating to the locals. There could be some initial suspicion, but as they get to know Harry and Teddy better, they could form strong bonds.
One adventure could be related to the local werewolf pack. Teddy might have to prove himself to them. Hermione could be the one to mediate any conflicts that arise. They could also go on a journey to find a lost spell book that is said to be hidden in La Push. Along the way, they'd face challenges like rough terrains and other supernatural beings that don't want them to find the book.
Well, perhaps Teddy is in some sort of danger. Maybe he's being targeted by dark wizards because of his connection to Harry. Harry, being the heroic type, decides to fight to protect Teddy. He could use his magic skills and the support of his friends like Hermione and Ron to keep Teddy safe.
Well, perhaps in the fanfiction, Harry adopts Teddy after Teddy has some trouble at Hogwarts. Harry steps in as a father figure. He teaches Teddy advanced magic, things he learned from his own adventures. They might also have a trip around the world of magic together, visiting different magical communities and learning about diverse magic cultures.
One possible plot could be that Harry and Ron arrive in Forks and are immediately struck by how different it is from the wizarding world. They might struggle to adapt to the normal human lifestyle. For example, they could be confused by Muggle technology like cars and electricity. Maybe they meet the Cullens from Twilight series in Forks. Since they are wizards, they might initially be seen as a threat by the Cullens, but then they figure out that they can all co - exist peacefully. They could also use their magic to help out in Forks in some way, like protecting the town from natural disasters using spells.
Well, perhaps the plot could involve Harry and Draco putting aside their past differences to give Teddy a stable and loving home. They might struggle at first with co - parenting due to their long - standing rivalry. But as they get to know Teddy better and see how much he needs them, they start to work together more smoothly. Maybe they also have to protect Teddy from some dark forces that are after him because of his parents' history.
Another idea is that they travel to a time just after the end of the First Wizarding War. There is chaos and rebuilding going on. Harry and Teddy could be on a mission to retrieve a powerful magical artifact that was lost during the war. Along the way, they meet survivors of the war and learn about the true cost of the conflict. Teddy, who has grown up in a post - Voldemort world, is deeply affected by the stories of those who lived through the dark times.
