They might become more protective of each other. Since they are both responsible for the baby, they would need to work together even more closely. Their love could deepen as they see each other in the role of a parent.
The arrival of the baby could also add some stress to their relationship. There could be disagreements on how to raise the baby, especially considering the unique situation of a half - vampire baby. For example, Emmett might be more lenient while Rosalie could be more strict. But through these differences, they could learn to communicate better and grow stronger as a couple.
Their relationship would likely become more centered around the baby. They would have to cooperate even more closely to take care of the little one. There would be less time for their own personal issues as the baby's needs would be top priority.
With the baby's arrival, they would have less time for just the two of them. But this could bring them closer in a different way. Spock might become more in touch with his emotions because of the baby, and Uhura would be more understanding of Spock's Vulcan side as they navigate parenting. For example, when the baby has a fever, Spock uses his Vulcan knowledge to try and cool the baby down, and Uhura is impressed by his calmness and resourcefulness.
Their relationship can become more protective. Logan will be extra vigilant about keeping Rogue and the baby safe. Rogue might become more dependent on Logan in some ways, especially when it comes to physical protection. Also, they might have more tender moments as they take care of the baby together.
The twin could create jealousy in Rosalie if Emmett shows too much interest in the new character. Since Rosalie is very protective of her relationship with Emmett, any threat, even if it's just a perceived one from her twin, could cause a rift between her and Emmett. On the other hand, it could also strengthen their bond if they work through it together.
Well, in fanfiction, Rosalie and Emmett's daughter could have a very different personality from her parents. Maybe she's more of a peacemaker compared to Rosalie's sometimes fiery nature. She might befriend humans more easily, which could cause some tension within the vampire family as they try to keep their existence a secret. It could also lead to her having her own set of adventures, like trying to find a way to co - exist with humans without breaking the vampire laws.
One idea could be that the baby has a special power. For example, it might be able to communicate with animals in a way that surprises everyone in the family. Another plot could revolve around the challenges of raising a half - vampire baby, like finding suitable food sources that won't harm the baby or its development.
In fanfiction, Rosalie and Emmett's love could be explored through different scenarios. Maybe a story could be written about how they first fell in love. It could start with Emmett's admiration for Rosalie's beauty and grace, and Rosalie being drawn to Emmett's fearless and fun - loving personality. Their love might also be depicted as a journey of self - discovery for both of them, as they learn more about themselves through their relationship.
One possibility could be that their daughter has special powers. In the Twilight universe, it's not unheard of. Maybe she has a unique ability to control the elements, which sets her apart from other vampires. This could lead to a whole new set of adventures and challenges for her as she tries to keep her powers a secret from the human world while also dealing with vampire politics.
Their relationship would likely become more centered around the baby. They would have to make decisions together as parents, which might cause some initial disagreements. For example, Rumple might be more protective in a way that Belle thinks is too overbearing.
Their relationship could grow deeper as they face new challenges together. Raising two children is different from one. They would need to divide their attention and time, and through this process, they might understand each other's strengths and weaknesses better. For example, Harry might be better at teaching the kids defensive magic, while Ginny could be great at instilling values and courage. This mutual understanding would strengthen their bond.
