In the fanfiction, perhaps Elladan and Elrohir would be intrigued by the Dwarves' craftsmanship. The Dwarves, in turn, might be impressed by the Elves' grace and magic. They could end up sharing stories around a campfire, forging an unlikely friendship.
Well, it could start with a bit of tension. The Elves' refined ways might seem strange to the Dwarves, and the Dwarves' rough - and - tumble nature could be off - putting to the Elves. However, as they face challenges together, like a group of orcs attacking, they would come to respect each other. Elladan and Elrohir could learn about the Dwarves' loyalty to their clans, and the Dwarves could see the Elves' deep connection to nature.
They could start with a formal greeting. Given the history between Elves and Dwarves, they would be polite but reserved.
One common theme is friendship. Since the original characters (OCs) are often inserted into the world with Elladan and Elrohir, the development of friendship between them is a big part. For example, the OC might start as a stranger and gradually become a trusted ally.
One interesting story could be about their early adventures in the forest near Rivendell. Maybe they discover a hidden glade filled with magical creatures. Another could be about their first attempts at learning elvish archery from their father, Elrond.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are often many Tolkien - related fanfictions there, and you can specifically search for ones about Elladan and Elrohir as babies. Another place could be some Tolkien - focused forums, where fans might share their own written works or recommend good fanfictions.
Another interesting one is 'Among the Elves: Elladan, Elrohir and OC'. This story dives deep into the elven culture and how the OC adapts to it while being in the company of Elladan and Elrohir. It shows their daily lives, their training, and how they interact with other elves. The descriptions of the elven settings are really vivid, making you feel like you're right there in Middle - earth.
In fanfiction, when the Weasleys meet Sirius, there could be a lot of excitement. Sirius might share some of his wild adventures from his younger days. The Weasleys, being a large and warm - hearted family, would likely welcome him with open arms. Maybe they would exchange stories about the wizarding world, especially those related to the Order of the Phoenix.
Maybe there would be some sort of cultural exchange. The Malfoys are used to the magical ways and traditions that have been passed down in the wizarding world for generations. The Grangers, on the other hand, bring in fresh, Muggle - influenced ideas. They might share knowledge about things like Muggle technology with the Malfoys, while the Malfoys could introduce the Grangers to some rare magical artifacts or spells that are not commonly known outside pure - blood families.
Well, in some fanfictions, the Dursleys might be completely bewildered when they meet Teddy. Teddy, being a wizard like Harry, could show off some magic accidentally, which would terrify the Dursleys as they are so used to the non - magical world and have always been afraid of magic.
In some fanfictions, when the Dursleys meet Sirius, there could be a lot of chaos. Sirius, being a wizard, might shock the Dursleys with his magical abilities. They would probably be terrified and try to get away from him as they are not used to magic. Maybe Sirius would try to take Harry away from them right then and there, leading to a big confrontation.
Well, they might start off as rivals. The protectors could see the brawlers as a threat to the peace they are trying to maintain. Maybe there would be some initial skirmishes or misunderstandings between them.
