Thor may also find it amusing in a way. He's from a different world with different problems, and a human losing their glasses could seem like a very minor yet strange thing to him. He might tease Darcy a little about it, but all in good fun, while still being concerned about her well - being.
She might immediately start feeling around on the ground for them. After all, she can't see well without them.
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.
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.
Well, she might have trouble seeing clearly. Maybe she stumbles around a bit, which could lead to some comical situations. For example, she could accidentally bump into Thor or other characters, causing some light - hearted banter.
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.
She might be embarrassed too. She could be self - conscious about not being able to see well and worried about making a fool of herself in front of others at the party. Maybe she's constantly squinting or trying to hide her face a bit because she doesn't have her glasses. Also, she could be a bit scared that she won't be able to find them and will have to go through the trouble of getting new ones. It's a very uncomfortable situation for her, and these feelings can add a lot of depth to the story in the fanfiction.
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.
In a fanfiction, it could be a plot device. For example, as Darcy drops her glasses, she might accidentally discover some hidden clue on the ground that is related to a bigger threat the Avengers are facing. And Thor could be the one to help her make sense of this new discovery, leading to a joint adventure where they have to work together to solve the mystery.
In the fanfiction, when Darcy's glasses fall off, it might be a plot device to create some chaos. For example, she could have been in the middle of an important experiment or task related to Thor's world, like analyzing some Asgardian artifact. Without her glasses, she makes a mistake that sets off a chain of events. Maybe she misreads some symbols on the artifact and accidentally activates a strange power that Thor then has to deal with.
Rosalie might initially be taken aback. Since she is used to being in control and having a certain level of respect, Bella's outburst could shock her. She might just stand there for a moment, not knowing how to respond immediately.
