There could be a number of reasons why such a scenario might be in a fanfiction. It could be used for comical effect, like she's in a rush to see something important in the Avengers' world and can't find her glasses. Or it might be part of a more character - building moment where she's a bit flustered and her groping for glasses shows her more human side in the midst of all the superhero action. But without actually finding the specific fanfiction, it's hard to say more.
She could finally find her glasses and then notice some crucial detail about Thor or a new threat approaching. For instance, she might see a strange symbol on Thor's hammer that she hadn't noticed before.
It could be a simple moment of clumsiness that adds a touch of humor to the fanfiction. Maybe Darcy is in a hurry to see something important related to Thor or the Avengers' activities, and her groping for glasses shows her distracted state.
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.
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!
To find that specific fanfiction, you first need to know where most Avengers fanfiction is hosted. As mentioned, AO3 and FanFiction.net are popular. When you search, be sure to use the full set of keywords 'Darcy groping for glasses Avengers' to narrow down the results as much as possible. Additionally, some smaller fanfiction communities might also have relevant stories. You can explore these by looking for Avengers - themed fanfic forums or sub -reddits. Don't forget to check the tags and summaries of the stories that come up in your search to make sure they really match what you're looking for.
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.
Maybe she was startled by something sudden, like Thor using his powers or a loud noise. In many fanfictions, characters can be caught off - guard in such situations, causing their accessories like glasses to fall off.
Maybe Thor, being the chivalrous god he is, might pick up Darcy's glasses for her. He could use this simple act to start a friendly conversation with her, perhaps asking about the purpose of these strange 'eyeglasses' as they don't have such things in Asgard.
Yes, there might be. Some could focus on how Darcy's glasses are a part of her identity in the Avengers and Thor universe. They might explore how other characters react to her with or without her glasses. For instance, Thor might find her just as charming with or without them, but others might have different opinions.
