In this fanfiction, it might be due to his poor living conditions. He doesn't always have the best food or a warm, clean place to stay. His body could be weakened from not getting enough nutrition, which makes him more likely to get sick. Also, the emotional turmoil he goes through with losing friends and dealing with the Socs could take a toll on his immune system.
Ponyboy Curtis is a complex character. He's sensitive and intelligent. He loves to read and watch movies, which sets him apart from some of the other greasers. He has a strong sense of loyalty to his gang, the greasers. For example, he's always there for his brothers, Sodapop and Darry, even when they have their differences. His love for his friends is also evident in how he stands up for them during the rumbles with the Socs.
The other characters' reactions could vary. Some of the more hot - headed gang members might initially be impatient about Ponyboy being sick and not being able to participate in their activities. But as they see how serious it is, they would come around. The Socs, if they knew, might not care much on the surface, but there could be a few who feel a bit of sympathy, especially if they start to see Ponyboy as more than just an 'outsider'. And the girls in the story, if there are any, would probably be very motherly and bring things like soup and warm blankets for Ponyboy.
If Ponyboy was a girl, her relationship with Sodapop would likely be different. Sodapop might be more protective of her. Their sibling bond could have a different dynamic, with Sodapop perhaps being more cautious about her getting involved in the gang's activities.
One possible reason could be that he's a Greaser. The Socs might see him as an easy target just because of the group he belongs to. They might want to show their dominance over the Greasers.
In fanfiction, Ponyboy and Cherry's kiss can be seen as a moment of connection between two very different characters. It might represent a brief escape from the harsh reality they both face in their different social groups. It could also symbolize the potential for understanding and unity across the social divide in 'The Outsiders' world.
One possible plotline could be that Ponyboy and Sodapop get caught in a sudden storm while out in the open. They're both scared as lightning strikes close by. They huddle together in an abandoned building, sharing their fears and memories from their tough lives. This situation could strengthen their bond and lead to some deep conversations about their dreams and hopes for the future.
One plot idea could be that Sodapop and Ponyboy go on a road trip together. They face various challenges on the road, like car troubles and meeting some interesting characters. This would allow for a lot of character development and some really sweet moments between them as they rely on each other.
