I think her mother, Lily, would be an important character in some fanfictions. Lily has a lot of influence on Serena's life. Although their relationship is complicated, Lily might step in to help Serena during her panic attacks. Also, Rufus could be another unexpected supporter. He has a warm heart and could offer Serena some fatherly advice when she is struggling with her panic attacks.
Dan could also be a great support. He has a deep understanding of Serena's complex personality. In fanfictions, he might use his writing skills or just his kind heart to help Serena get through her panic attacks. And of course, Nate. As Serena's long - time friend, he would be there to comfort her and make her feel safe during those tough times.
In these fanfictions, a common theme is Serena's attempts to hide her panic attacks from the public eye. Since she is a part of the high - society in the Gossip Girl world, she is afraid of the judgment. Another theme is the exploration of different coping mechanisms. Some fanfictions might show her trying yoga or meditation, while others might show her relying on her friends for support.
'The Rivalry Turned Friendship' is also quite well - known. It takes their on - screen rivalry and gradually turns it into a strong friendship, which is really appealing to fans who love to see character development in fanfiction.
In addition to the main characters from the original story, there could be new characters created by the fanfic author. For example, a therapist or a new friend who has had similar experiences with panic attacks. This new character could offer different perspectives and ways of dealing with Conrad's situation. But the core group of characters from the original source material would still be central to the fanfic.
Annabeth would be a likely helper. She's very perceptive and has been through a lot with Percy. She would probably be able to sense something was wrong and offer her calm and rational presence to help him through it. Grover could also be there. He's Percy's loyal friend and his empathy for Percy's situation would make him a great support. He might even use his nature - related powers to create a more soothing environment for Percy.
Blair could be a great character to pair with them. Her complex relationship with Serena and her history with Nate add a lot of drama. There could be a love triangle situation or they could all form an unlikely alliance to take on a common enemy.
Professor Sycamore could be a character involved in a surprising way. Maybe he discovers something about Ash that he believes is dangerous and tries to use Serena to stop Ash. Or perhaps there's a misunderstanding where Serena thinks she's doing the right thing by following the professor's orders which seem to go against Ash. It shows how complex the relationships can be in these fanfiction scenarios.
Definitely Ash, as he's the center of Serena's affections. But also, there could be new female characters created specifically for the fanfiction. These new characters might be trainers who are really good at Pokemon battles and catch Ash's attention. Serena would then become jealous of their skills and the attention Ash gives them. Additionally, any of Ash's Pokemon that seem to have a special connection with another character could also be part of the scenario that makes Serena jealous. For example, if Pikachu seems to like a new girl more than Serena, that could be a reason for her jealousy.
In fanfiction where Serena and Nate are married, it could start with a grand wedding that the whole Upper East Side attends. Their relationship might be filled with love and passion, but also drama. For example, Serena's friends might be jealous of her new life with Nate. And Nate, on the other hand, might have to deal with Serena's fame and the attention she gets. But overall, their marriage could be a symbol of a new chapter in their lives and in the Gossip Girl universe.
They need to explore the root causes of her panic attacks. Maybe it's the stress of being a Muggle - born in a wizarding world full of prejudice, or the fear of losing her friends in the war against Voldemort. By understanding the causes, the story becomes more believable.
The 'frenemy - to - besties' trope is also common. It shows how they can be rivals in some aspects, like for boys or social status, but then realize that their friendship is more important. It adds a lot of drama and tension that fans of 'Gossip Girl' love. For example, in some fanfics, they compete for the same guy at first but then end up supporting each other instead.
