The gang would be extremely worried. Shaggy might be shaking more than usual and Scooby would be whimpering. Fred would start coming up with plans to rescue her right away, using his knowledge of traps and such.
The gang's reaction would be intense. Fred would be focused on finding a way to rescue Velma. He'd use his skills in engineering and planning to come up with a rescue strategy. Daphne would be the emotional support for the group, keeping everyone's spirits up. Shaggy and Scooby, despite their fear, would be determined. Shaggy would keep thinking back to any strange occurrences before the kidnapping that could give them a lead. Scooby would be using his nose to sniff out any traces of Velma or the kidnappers. They would all be united in their goal of bringing Velma back safely, and they wouldn't rest until she was found.
The character would likely feel extremely vulnerable. Without their glasses, their vision is impaired, making the whole situation scarier. They might react by trying to stay calm and use their other senses to figure out where they are. For example, they could listen for any familiar sounds or feel the texture of the place they're in.
She might be in real trouble without her glasses. Since she is often the brains of the group, not being able to see clearly could make it hard for her to find a way to escape. Maybe she tries to use her other senses like hearing to figure out where she is.
The Avengers would be extremely concerned. Captain America would immediately start strategizing a rescue mission. Thor might be angry and ready to use his strength to find her. Black Widow would use her espionage skills to gather information on the kidnappers. And Iron Man would likely use his technology to track any possible leads, all while being aware that Darcy without her glasses might be in a more difficult situation.
Perhaps the girl without glasses has a special ability that she's not fully aware of. The kidnappers, who are part of some sort of secret organization, know about this ability. They kidnap her to study her or use her power for their own purposes. As she's held captive, she starts to discover more about this ability herself and tries to use it to escape.
I'm not sure which specific 'Kidnapped Felicity Squints Without Glasses' fanfiction you're referring to. There could be many different interpretations and stories within that concept. Maybe it's about Felicity being kidnapped while in a situation where she's not wearing her glasses and has to rely on other senses or the help of others to escape.
In this fanfiction, Blurry without glasses might be on a quest to rescue Felicity. Their journey could be filled with obstacles not only because of the danger of the kidnappers but also because of their impaired vision. This could lead to some really intense and exciting scenes as Blurry tries to navigate and find Felicity.
Harry would likely be defiant at first. Even without his glasses, he has his inner strength. He would probably try to resist Voldemort's every command and look for opportunities to escape or fight back.
If this is a fanfiction, it might explore themes of vulnerability and heroism. Felicity being kidnapped puts her in a vulnerable position. Blurry without glasses could be seen as less capable at first, but perhaps they overcome this disadvantage to rescue Felicity. It could also involve a lot of character development for both Felicity and Blurry as they face this difficult situation.
One possible fanfiction could be that the girl who was kidnapped was a very shy and nearsighted person. Without her glasses, she could barely see. The kidnapper might have targeted her because of some special ability she unknowingly had. As she was squinting in the dark place where she was held, she started to recall all the mystery novels she had read, trying to find a way to escape using the little she could see and her wits.
Her friends could be really surprised. They're used to a more composed Daria. They might first be concerned because she's not wearing her glasses and then realize she's drunk. Some might try to take care of her, while others could be a bit more amused at seeing this different side of her.
