In fanfiction, Edward's reaction could vary greatly. Some stories might depict him as being overjoyed and excited, ready to embrace fatherhood. However, considering the unique situation of a vampire and a human having a baby, he could also be very apprehensive. He may think about how the baby will grow up, whether it will be accepted in their world. He might also be concerned about Bella's transformation, if that becomes necessary for her survival during or after the pregnancy.
Ezra's reaction could be complex. First, he might need some time to process the news. He could worry about how their families and friends would react, especially considering their relationship might have had some ups and downs. However, once he gets over the initial shock, he would likely embrace the situation wholeheartedly. He would be there for Aria every step of the way, attending doctor's appointments with her, and getting ready to be a father. He might also start thinking about how to balance his career and family life in the fanfiction world.
Lucas could also be overjoyed. He might immediately hug Riley tightly and start talking about their future together, like how they will decorate the baby's room and all the fun things they will do as a family.
He might be initially shocked. Vegeta is a tough Saiyan, but deep down he has feelings. He could show a rare moment of vulnerability, maybe just standing there in silence for a while, trying to process the news.
Jacob might feel extremely angry. In the Twilight series, Jacob has strong feelings for Bella. Seeing her kiss Edward would be like a slap in the face. He could feel betrayed and might even lash out at them.
Edward's reaction can vary greatly depending on the specific fanfiction. In some, he's overjoyed right away, seeing it as a new chapter in their lives. In others, he's more cautious, worried about Bella's health and the future of their family. He could start making plans immediately to ensure Bella's safety and the well - being of the baby.
Remus might be initially surprised. He could show great interest as he is generally a good listener. Maybe he'll give Hermione some advice on her writing, like how to improve the plot or develop the characters better.
Bella would likely be very frightened during the car incident. Once Edward saves her, she'd be extremely relieved and probably feel even more attached to him. Edward, on the other hand, would be initially worried and focused on getting Bella to safety. After saving her, he might feel a sense of relief as well, but also a bit of that over - protective feeling that he often has for Bella.
Edward might seek revenge if he believes Bella's death was caused by someone. He would use his vampire abilities to track down the supposed culprit. For example, if he thought a rival vampire or a group of humans were involved, he'd be relentless in his pursuit. His sense of loss would fuel his anger and drive for vengeance.
They could be very protective. After all, Edward is their son. So they might be a bit cold to Bella at first, sizing her up.
Gajeel might be initially shocked. He could then feel a rush of joy and immediately start planning for the future, like thinking about how to make a safe and happy home for the baby.
