In some fanfictions, Snape might yell at Draco because he expects more from him. Draco is from a prominent pure - blood family, and Snape, being strict, wants Draco to uphold certain standards. Maybe Draco made a mistake in potions class, or he showed disrespect towards other students. Snape's yelling could also be a way to protect Draco from getting into more serious trouble in the dangerous Hogwarts environment.
One reason in fanfiction could be that Snape is frustrated with Draco's lack of focus. Draco might be too preoccupied with his family's reputation or his own petty rivalries at Hogwarts. Snape, who values discipline and academic excellence, yells at him to snap him out of it. For example, if Draco is slacking off in Defense Against the Dark Arts, Snape may yell at him to remind him that he needs to be better prepared for the real threats that exist in the wizarding world.
Well, it could be that Snape yells at Draco in fanfiction due to Draco's association with the wrong crowd. Snape might see Draco getting involved with Death Eaters - in - training or those with bad intentions. Snape, having his own complex past and loyalties, may be trying to steer Draco away from a dark path. He yells to get Draco's attention and make him realize the seriousness of his actions.
In fanfictions, Draco may yell at Harry due to jealousy. Harry is often the center of attention and gets all the glory. Draco, who comes from a proud pure - blood family, might feel overshadowed and this could lead to him yelling in frustration.
Perhaps it's related to Harry's association with his father, James Potter. Snape had a long - standing grudge against James, and seeing Harry might bring back those bitter memories. So, whenever Harry does something that reminds Snape of James, like being overly confident or a bit of a troublemaker, he yells at him.
Snape might be protective of Draco in fanfiction because in the original series, Snape has a certain loyalty to the Slytherin house. Draco is a young Slytherin, and Snape could see a bit of his own past self in Draco. Also, Snape was tasked with some difficult and dangerous missions by Voldemort. He might want to protect Draco from getting too deeply involved in Voldemort's dark plans to spare the boy from a similar fate as his own.
Snape could also punish Draco by deducting house points. Since Draco is in Slytherin, losing house points is a big blow to his pride and to the whole Slytherin house. This would make Draco the target of his housemates' ire, adding to the punishment's severity.
Snape might force Draco to protect him. Snape has his own complex motives in the wizarding world. By forcing Draco to learn certain skills or follow certain paths, he could be ensuring Draco's survival. For example, in some fanfictions, Snape sees Draco as a key to maintaining some sort of balance in the Slytherin house or within the Death Eaters' influence.
Another reason could be related to Peter's mistakes. He may make errors during a mission that put the whole team or the city at risk. Tony, who has a lot of responsibility on his shoulders, might yell at Peter as a way to make him understand the seriousness of his actions and to prevent future mistakes.
Snape, being a skilled wizard, could use magic to protect Draco. He might cast protective spells around Draco when he's alone or in vulnerable situations. Maybe he uses a spell that alerts him whenever Draco is in danger, so he can rush to his aid immediately.
He might yell because he is startled by the strange things around him in the story.
Well, Snape's care can make Draco more confident. Knowing he has someone like Snape looking out for him gives him a sense of security. This can lead to Draco being less arrogant and more self - aware. He might start to question some of the pure - blood supremacist ideas he was raised with, as Snape's care could show him that there are more important things than just blood status.
One reason could be that Lupis's actions had negative consequences for Ainz or their associated group. If Lupis's deeds led to losses, whether it was of resources, reputation, or something else, Ainz might yell at her out of anger and disappointment.
