A girl who finds a glory hole by mistake should take quick action. She needs to step away to protect her own well - being. She can then think about how to handle the situation. If it's in a public restroom, she might want to inform the janitorial staff or the management. If she feels it's something more serious, like part of an illegal activity, she should call the police. It's important for her to assert her right to a safe and appropriate environment and not be afraid to take steps to correct the situation.
Well, the first consequence could be psychological. She'd likely be horrified as it's an inappropriate and unexpected discovery. Then, from a safety perspective, she might worry about the environment she's in. And she'd probably take steps to ensure that such a thing is removed or the area made safe. For example, if it's in a restroom she uses regularly, she'd want the management to take action.
If she finds it in a public place, she should probably find an appropriate authority figure, like a store manager if it's in a store, and let them handle it in a proper and discreet way.
She should immediately tell an adult she trusts, like a parent or a teacher. Adults can help deal with the situation properly and make sure it doesn't happen again.
She could try to communicate her feelings. Just tell him that she noticed and it made her a bit uncomfortable.
The girl has a terrifying adventure. She's scared but also curious to know more about the ghost.
Naruto would probably be very friendly and kind. He has a big heart, so he'd likely greet her with a big smile and start chatting right away, asking her name and where she's from.
She should respect her mom's privacy and not read it without permission. If she has already read some parts, she might consider talking to her mom honestly about it and apologize for invading her privacy.
Hermione would likely be a mix of disappointed and worried. Disappointed because Harry is usually responsible, and worried because she cares about him. So she'd probably try to figure out why he got drunk in the first place.
She probably comforts him right away. Hermione is a very empathetic person. She might give him a big hug and let him cry on her shoulder.
She might immediately go to comfort him. Annabeth is a strong character, but she also has a soft side for Percy. She could hold him and let him cry it out without asking too many questions at first.
