Percy would likely experience a whole range of emotions. Initially, he could be in denial, thinking that Annabeth will be back soon. As time passes and he realizes she's not coming back right away, he'd feel overwhelmed. He has to take on a role he may not have been fully prepared for. He'd be worried about making mistakes with the child, but also he'd start to develop a deep bond with the child. This new relationship would give him a new sense of purpose, while still longing for Annabeth's return and the family they could have had together.
Percy would be really hurt. He loves Annabeth, and her leaving would make him question their relationship. At the same time, he would feel a strong sense of protectiveness towards the child. He would be determined to do his best for the child, even though he's not sure how. He might also feel a bit of anger towards Annabeth for leaving him in such a difficult situation, but deep down he would still hope for her to come back.
Percy would probably feel a mix of shock and confusion at first. He might wonder why Annabeth left him with this huge responsibility. Then he would start to feel a bit scared because he doesn't know if he can take care of the child properly.
He'd probably be devastated. Percy loves Annabeth deeply, so this would be like a punch in the gut for him.
He could go on a desperate search for her. Percy is a very determined person. He would try to find out the reason for her leaving. He might ask all their mutual friends and look for clues everywhere. Meanwhile, he would also be trying his best to take care of their child. He would be heartbroken but also focused on keeping their family together in some way.
Annabeth would likely be furious at first. She has been through so much with Percy, and for him to leave her for Calypso would seem like a betrayal. But then, she might also start to reflect on their relationship and what went wrong. She could become determined to win Percy back or to move on and prove that she doesn't need him.
Perhaps Annabeth is forced to leave because of a prophecy. She believes that by leaving Percy with the child, she is protecting them both in some way. Percy then has to struggle with his own feelings of abandonment while also trying to raise the child. He might seek help from his friends at Camp Half - Blood, like Grover. Grover could help him understand the child's needs better as he has some experience with young creatures. The story could then follow Percy's journey of self - discovery as he becomes a more responsible and loving father.
Annabeth would probably be very hurt at first. She has a strong bond with Percy, and his leaving for someone else would be a huge blow to her self - esteem and her heart.
Percy could be heartbroken. He might initially go into a state of denial, not believing that Annabeth would actually leave him for a mortal. He might keep thinking there was some mistake or that she was being influenced in some way.
Well, Percy could have a range of reactions. At first, he might be in denial, not believing that Annabeth would actually leave him for a job. Then, as it sinks in, he could get angry. He's a passionate guy, and this would be a big blow to him. He might also feel a bit of envy towards the job that seems to have taken Annabeth away from him. In the long run, though, he could use this as a chance to grow on his own and become more independent.
In such a fanfiction, the relationship between Annabeth and Percy would be in tatters. Annabeth would have to deal with the fact that the person she loved and trusted left her at such a crucial time. Their friends' relationships would also be affected. Those who are closer to Annabeth would probably cut off ties with Percy. However, there could be a chance for redemption. If Percy realizes his mistake and tries to make amends, it could lead to a slow rebuilding of their relationship, but it would be a long and difficult process, especially with a baby in the picture.
Percy's reaction could be complex. Initially, he'd be hurt and angry. But as time passes, if Annabeth is sincere in her attempts to get him back, he might start to question his own feelings. He could be torn between his love for her and the pain of the betrayal.
Well, one reason could be that in the fanfiction, the writer might want to explore a different dynamic. Maybe Annabeth gets lured by Luke's charm that has been newly developed in the fanfic. Luke could be presented as more understanding or having a different kind of allure that attracts Annabeth away from Percy.
