Sirius may also be angry at first. Given his protective nature towards Harry, if he misinterprets the situation as Draco causing trouble for Harry, he would likely step in assertively. But if it's a situation where Harry and Draco have a more positive or friendly interaction in the fanfiction, Sirius would have to re - evaluate his initial reaction.
Another possibility is that Lucius could be initially confused. He might not understand what he's seeing at first. After all, Harry and Draco are supposed to be enemies in the general wizarding world view. He could stand there for a moment, trying to process what's going on before taking any action.
Well, depending on the context of the fanfiction, Sirius could also be very understanding. If he knew that Harry and Hermione were just having a private conversation about important matters like their fight against Voldemort or schoolwork, he might just give them a knowing smile and say something like 'Carry on, then. Just making sure everything's all right.' He's a rather perceptive character, after all. And he trusts Harry a great deal, so he would likely give them the benefit of the doubt before assuming anything untoward.
Well, Ron could get angry. He has a strong loyalty to Harry, and seeing Harry with Draco, who he has always seen as an enemy, might make him feel betrayed. He might immediately jump to conclusions and start shouting or demanding an explanation from Harry.
One possible reaction of Sirius could be shock. He might stand there frozen for a moment, unable to believe what he's seeing. Another reaction could be anger. If Sirius has certain expectations or feelings about James and Regulus' relationship, he could get angry at finding them together. Or he could be confused, trying to figure out how and why this is happening between his friend James and his brother Regulus.
He might be shocked. Draco has always seen Harry as an equal rival in some ways, but finding out he is Lord Black means Harry has a whole new level of status. So, shock is a very likely initial reaction.
Reactions could vary greatly. Some might freeze in panic, while others might try to explain or make excuses. But in any case, it's a highly stressful and embarrassing moment.
Draco may initially react with disbelief. But as he realizes it's true, he could have a complex range of emotions. He might be disgusted by the act itself. His Slytherin nature might make him want to be cunning in dealing with the situation, perhaps by finding out more about the incident in a secretive way. He could also have a moment of self - reflection, thinking about how his own actions in the past might have added to Harry's stress or made him more vulnerable. And ultimately, he could be motivated to help Harry heal, whether it's through emotional support or taking more practical steps like helping him report the crime if that's applicable in the fanfiction world.
One possible reaction could be shock. Carlisle might be momentarily stunned to see them in an unexpected situation. He could quickly compose himself and offer some words of wisdom or caution. For example, he might remind Edward to be extra careful with Bella considering her human nature.
This kind of content is not appropriate and goes against common decency. We should focus on positive and meaningful subjects instead.
She would probably be furious at first. Harry is known for her strong will, and being forced into a marriage, especially with Draco, would go against everything she believes in. She might try to fight it directly, using her magic skills to break free from whatever is forcing this marriage.
