Fighting with the Half-Blood Prince at Hogwarts

"Professor McGonagall! I reported Eli Thorne for violating school rules. After curfew last night, I saw him entering the library with my own eyes. He must have gone to peek at those banned books!" James Potter's tone was full of certainty. Professor McGonagall pushed up her glasses: "Mr. Potter, Eli is a good boy. The prefect did not report any abnormalities during the curfew period. The dormitory records also show that he went to bed on time. How did you see Eli in the library after curfew time?" "Professor Slughorn! Eli Thorne used unknown methods to tamper with the formula in Potions class and almost caused the entire pot to explode!" Severus Snape held the parchment stained with potion in his hand. Slughorn twirled his beard and shook his head with a smile: "Mr. Snape, I have already checked the ingredients of that potion. It is a problem with the potion material. Eli is a good boy, and all this has nothing to do with him." "Professor Binns! Eli Thorne can talk to the ancient wizard in the portrait. This definitely goes against the rules of the magical world!" Lily Evans stopped Professor Binns with confusion in her voice. Professor Binns' figure swayed translucently and responded calmly: "The magical world is full of unknowns. It is not against the rules to communicate with portraits. Eli is a good boy. Don't be too sensitive to abnormalities." "I'm such a good boy, why don't you believe me?" Eli Thorne looked at James Potter and Severus Snape who fell in front of him, and shook his head.
