My partner at Hogwarts is Tom

In a surprising turn of events, renowned author and Magizoologist Victor Scamander returns to his alma mater, Hogwarts School of Witchcraft and Wizardry, as a professor, accompanied by his trusted friend and expert mouse catcher, Tom. As they arrive on campus, Victor proudly introduces Tom to the students, asserting that the latter is the world's leading mouse catcher. However, this boastful statement is met with skepticism by Tom, who is not one to back down from a challenge, especially when faced with a formidable foe like Voldemort, who mockingly asks what qualifies Tom to be considered on par with someone with the same name.
