Tom tricked Li Weide into sending romantic gifts and letters to more than a hundred Hogwarts girls, leaving him branded the school’s Number One Sea King.

• Grace believed Tom’s explanation and began passing it along to the other girls, while Tom judged that the rumor would eventually clear Li Weide’s reputation.

Li Weide returned to the Moving Castle and agreed with Miravia that the world needed a revolution, while she hinted she might accept his confession if he achieved his ambitions.

• Miravia told Li Weide that the suffering she had seen in the war convinced her the world needed a great revolution, and she agreed to help him.

The diadem advised him to earn Nicolas Flamel’s trust and seek his help, leaving Li Weide hopeful that mentorship could bring him closer to using or making a stone.

• Li Weide asked Ravenclaw’s Diadem whether it knew how to create the Philosopher’s Stone, and it explained that Ravenclaw had researched the subject but abandoned it as impossible with the alchemy of her era.
• Li Weide wondered whether the Philosopher’s Stone had existed before the Four Founders and whether it explained Hufflepuff’s longevity, but the diadem said it had no evidence and could not explain how she lived so long.
• The diadem assessed that Li Weide’s talent was exceptional but his alchemical foundations and experience were far behind Nicolas Flamel’s, estimating that he would need decades of study before he could attempt to make a stone.
• The diadem suggested that Li Weide use his talent to become Nicolas Flamel’s student, potentially gaining access to Flamel’s Philosopher’s Stone or help making his own.
• Li Weide agreed that earning Flamel’s trust and borrowing the stone would be more practical than trying to create one himself.

• Spike knocked Tom Cat unconscious during the fight, and Li Weide was startled to see how much the bulldog had changed.
