One common theme is the 'fish out of water' concept. Thor is from Asgard and Darcy is from Earth, so there's a lot of exploration of how Thor adapts to Earthly things with Darcy's help. Another theme is the power of friendship. They come from different worlds but form a strong bond.
Another aspect is that they could be allies in various adventures within fanfiction. Darcy's scientific knowledge and Thor's physical strength would make them a formidable team. They might face off against villains or solve mysteries together, with their friendship or relationship growing stronger through these shared experiences.
One idea for this fanfiction could be that Darcy loses her glasses in a chaotic event involving Thor and the Avengers. Without her glasses, she has to rely on her other senses more. Thor, being the noble hero he is, starts to protect her more closely. As they spend more time together, they develop a deeper bond, and Darcy discovers a new side of herself that she was hiding behind her glasses.
A romantic plot often involves overcoming differences. Since they are from different worlds, there are cultural and power - level differences. Fanfictions may explore how they deal with jealousy from other characters, or how they make their relationship work despite the challenges. Maybe Thor has to introduce Darcy to Asgardian society, which has its own set of rules and traditions.
In fanfiction, Darcy squinting could be a sign of her trying to figure out a mystery involving Thor. It could be that there are some secrets about his past or his true intentions in the story. She might be using her observational skills, shown by the squinting, to piece together the puzzle.
One popular 'Thor Darcy' fanfiction is 'A Thunderous Bond'. It explores an unexpected connection between Thor and Darcy in the aftermath of the events in Asgard. Another great one could be 'Darcy and the God of Thunder', which delves into how Darcy's scientific mind and Thor's otherworldly powers interact in a series of adventures.
It could be that they fell behind a piece of furniture or were accidentally taken by another character. You'll have to keep looking in unexpected places!
It could imply that she's curious about him. Her squinting might be her way of trying to understand Thor better, which could be a sign of a growing relationship, whether it's a friendship or something more. Maybe she's interested in his world and his powers, and the squinting is a physical manifestation of that interest.
One possibility could be that in this fanfiction, Darcy without glasses might have a more confident and alluring look. She could catch Thor's attention in a new way. Maybe she's at an Avengers party and without her glasses, Thor mistakes her for someone else at first, leading to an interesting encounter.
He might have been a bit confused at first. After all, glasses are not something he's used to seeing in Asgard. But then he could have quickly reacted with his natural heroism and tried to help her find them.
