It could also be due to the pressure of living up to everyone's expectations. Archie is seen as a bit of a local hero in Riverdale. He's expected to be strong, brave, and always there to help. This constant pressure might keep him awake at night, tossing and turning as he thinks about how to maintain that image.
Perhaps it's his family issues. Archie has had his fair share of family drama. His father's business problems or his mother's absence could be weighing on his mind at night. In fanfic, this could be explored further, like how he tries to deal with these emotions while still being a hero in Riverdale.
It could be due to an unrequited love. If Aramis has feelings for someone in the fanfic who doesn't return those feelings, it can be a source of restlessness. He might be lying in bed, thinking about this person and how to win their heart, thus unable to sleep.
It could be that Aria's creative mind is working overtime. Since she's an artsy person, she might be constantly thinking about her writing, art, or the various events in the PLL story from an artistic perspective. This over - stimulation of her creative thoughts can make it difficult for her to relax and fall asleep.
The themes usually revolve around loyalty. Archie and Betty are often portrayed as being loyal to each other through thick and thin in fanfics. There's also the theme of self - discovery. As they interact with each other, they learn more about themselves. For instance, Betty might discover a new side of herself because of Archie's influence. Also, the small - town life in Riverdale is a theme. How the town's gossip, traditions, and events affect their relationship is often explored in these fanfics.
The plot might involve Archie getting sick due to some sort of mystery in Riverdale. For example, there could be a strange virus going around that only affects certain people. Archie's sickness could be the starting point of an investigation. His friends, being the curious and caring bunch they are, start looking into what's causing it. This could lead to uncovering secrets in the town that were previously hidden. Also, Veronica might use her family's resources to try and find a cure for Archie.
Maybe the kid is too excited about something that happened during the day. Or, they could be scared of the dark or have had too much caffeine.
Another factor could be the events in the fanfiction world around her. For example, if there are threats to their camp or friends, Annabeth, being the strategic thinker she is, might be up all night planning defenses or thinking about how to counter the threats.
Well, I know a fanfic called 'Sunny Days with Archie and Betty'. In this one, they go on a series of adventures around Riverdale during the summer break. It's really cute as it shows their lighter side and how they bond over simple things like ice - cream and bike rides. Then there's 'Archie and Betty: The Secret Pact' where they make a pact to always be there for each other no matter what. It has some really heart - warming moments.
It has interesting storylines and engaging characters. The art style is also appealing.
One possible reason could be the stress of his ninja duties. He has so many missions and responsibilities that his mind is constantly racing, making it hard to relax and fall asleep.
They are closely related. Riverdale comics often feature Archie and his gang, and the Archie comics have elements that can be found in Riverdale.
