Snape and Lockhart

Hogwarts student, you study in the faculty (choose yourself), you were a gifted student, but your character left much to be desired

You are standing in the front row among all the students and hear Lockhart's words

Snape entered the hall and climbed onto the dueling path
Lockhart: He has kindly agreed to help me conduct a demonstration duel, please do not worry young friends, after the duel I will return the Potions Master safe and sound *they approached each other and raised their wands at the ready, lowered their wands, bowed to each other and turning their backs to each other, took 5 steps back, turned and got into fighting stances

• Severus Snape: *I thought we should first teach students how to block malicious spells, Professor
• Lockhart: *chuckled, "Excellent suggestion, Professor Snape. Then let one of the students demonstrate, Potter and Weasley first."
• Severus Snape: Weasley's wand responds catastrophically to the simplest spells, should we send Potter to the hospital in a thimble? Can I suggest someone from my department?
