In this fanfiction, they have a very close family - like relationship. The Cullens are like a big family, and Alice and Jasper are important members of it. They care for each other deeply.
In the fanfiction, they might have an intense reunion. Maybe there will be a lot of emotional exchanges, hugs, and smiles. They could start sharing their recent experiences and adventures right away.
In many fanfictions, when Alice and Jasper meet the Cullens, there could be a lot of emotional exchanges. Alice might use her power to foresee some potential events related to the Cullens. Jasper, with his ability to control emotions, could help ease any tensions within the group. They could also exchange gifts or tokens of friendship, strengthening their bond as a vampire family.
Carlisle, being the peace - loving and rational leader of the Cullens, would first try to understand Jasper's motives. He would probably try to communicate with Jasper to find out why he has kidnapped Bella and see if there is a way to resolve the situation peacefully.
Often, they are received with open arms. The Cullens value family and friendship. Since Alice and Jasper are part of their extended family, there would be hugs, smiles, and lots of chatter. They might immediately start sharing news about other vampires or events in the vampire world.
The other Cullens would likely be divided in their loyalties at first. Some might side with Alice, believing in her visions and her usually positive intentions. Others might understand Jasper's concerns, especially those who respect his military - like decision - making. This could create tension within the family.
Jasper might interact with the Cullens in a very protective way. Since he is aware of the importance of Bella's birth and the potential implications for the family, he could be on high alert. He would likely communicate his concerns and observations to Carlisle, given Carlisle's role as the family's leader and doctor. With Esme, he might share in her maternal - like worry for Bella and offer his calming influence.
Well, it could also have an impact on the group dynamic. Since they are part of a coven in 'Twilight', if Jasper uses his power on Alice, other members might take sides. Some might be on Alice's side, feeling that Jasper's action was wrong. Others might understand Jasper's motives, which could create division within the coven. Also, depending on the nature of his power use, it could potentially put Alice in danger or make her act in a way that is not in her best interest. This in turn could lead to problems for the whole coven as Alice's visions often play an important role in their safety and decision - making.
In a scenario where the Mikaelsons meet the Cullens, there could be some interesting alliances or rivalries. Maybe some of the younger members from both families might be intrigued by each other. For example, Klaus from the Mikaelsons and Edward from the Cullens could have a very tense relationship. Klaus is all about power and dominance, while Edward is more focused on protecting his family and Bella. Their different priorities could lead to some intense confrontations.
If the Cullens read Twilight fanfic, they might be either amused or appalled. Some fanfic might depict them in ways that are completely different from how they see themselves. For example, they could find some overly romanticized or out - of - character versions of themselves.
