In this scenario, it could also lead to a major shift in the relationships within the fanfiction. Hermione might feel betrayed if Draco doesn't stand up to his father. And Draco could be forced to make a difficult choice between his family's expectations and his feelings for Hermione. Lucius's interference could also bring in other elements of the wizarding world, like the Ministry or other pure - blood families getting involved depending on how the situation unfolds.
One consequence could be that Hermione becomes isolated from her original friends. Since she only trusts Lucius and Draco, her Gryffindor friends might not understand her actions and distance themselves from her.
She could face isolation within the Hogwarts community. The students might gossip about her newfound relationship with Lucius. Hermione may also become more involved in the darker aspects of the wizarding world if Lucius leads her that way. Her academic focus could shift as she gets caught up in the drama of this new relationship. Moreover, she may end up regretting leaving Draco if she later realizes that Lucius was just using her, and this could lead to a lot of emotional turmoil for her.
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, one possible consequence could be a major shift in the relationship dynamics between Hermione and Draco. It might start with shock and confusion among their friends. For example, Harry and Ron might be completely taken aback. Hermione herself could feel a strange mix of embarrassment and a new - found curiosity about Draco. Draco, on the other hand, might initially be smug but then start to have unexpected feelings for Hermione.
One consequence could be that he gains an unexpected ally in Draco. Draco might feel indebted to Harry and start to change his views towards him, which could lead to some interesting interactions between them in the future. This could also cause some tension among their respective groups of friends.
On the other hand, it could also lead to a change in their relationship. Draco might start to respect Hermione's boldness and intelligence. He could realize that his own behavior has been rather childish, and this could be a turning point in the fanfiction where they start to understand each other better, albeit reluctantly at first.
One possible plot could be that Lucius is trying to punish Draco for some disobedience or failure. Starving him could be a form of extreme discipline in a very dark and cruel Malfoy family dynamic.
One consequence could be that it creates a rift between Ron and Hermione. Hermione might be grateful to Lucius, which could make Ron jealous or angry. This could lead to a strain in their relationship, and they might have to work through their feelings about Lucius' interference.
Hermione herself would also develop. With the support of two former adversaries, she might gain more confidence in dealing with the pure - blood elite. She could learn to trust them and in turn, teach them things about the Muggle - born perspective. This triangular relationship could lead to all three characters growing in unexpected ways.
In the wizarding community at large, he could become an outcast. Other wizards and witches would likely look down on him, and he might find it difficult to get support or make alliances in the future. His actions could also lead to him being targeted by those who support Hermione and want justice for her.
