In fanfiction, how do Rose and Scorpius react when they get caught?

Well, they might face various consequences. Maybe they get scolded by their families or friends. It could also lead to a big misunderstanding that they have to clear up.

They usually react with shock and horror at first. After all, they've spent their lives denying the existence of magic. But as the situation unfolds, some might show a glimmer of curiosity, while others remain stubbornly resistant.

Percy would most likely go into a state of panic. His mind would be racing, thinking about all the teasing he'll get from his friends and what his mother would say if she found out. He might try to make a joke to ease the tension, but it would probably come out all wrong. Annabeth would be a bit more calm, but still mortified. She would be thinking about how this could affect their reputation in the camp, especially since they are both leaders in a way. She might give Percy a look that says 'this is all your fault' even if it wasn't really.

Some people react with shock. They might not be expecting to see someone crossdressing, so their immediate reaction is one of disbelief. For example, a friend might be completely stunned if they catch another friend crossdressing.

There are those who, when caught cheating, will try to shift the blame. In a business deal, if one partner is caught cheating on the contract terms, they might try to say that the other party didn't communicate clearly. But in general, being caught cheating often leads to a loss of trust. Whether it's in a friendship, a relationship, or a professional setting, once caught cheating, it's very difficult to regain the respect and trust of others.

Some characters might be shocked. They could never have expected Dexter to be involved in such situations.

They might use magic to create disguises so they can be together in public without being recognized. For example, they could use a glamour charm to change their appearances slightly.

Some people might feel embarrassed. If they are caught reading or having erotic stories in a public or inappropriate setting, it can be quite a shameful experience.

Definitely, Teddy Lupin could be in there. He could be a cool older cousin - like figure to Rose, showing her different aspects of the wizarding world that she might not have known. Then there's Astoria Greengrass, Scorpius's mother. Her backstory and how it affects the couple's relationship can be explored. And Blaise Zabini could be a side character, perhaps involved in some of the social events that Rose and Scorpius attend as a married couple.

First, look away to respect her privacy. Then, in a calm voice, say something like 'Mom, I'm sorry. I didn't mean to intrude.' And then, give her space. If she wants to talk about it later, be open and honest about it, like explaining that you just happened to be there by accident and that you'll be more careful in the future.
