Classroom off of the Charms corridor

"Professor McGonagall pointed them into a classroom that was empty except for Peeves, who was busy writing rude words on the blackboard."

- Narrative

This classroom was located off of the Charms corridor, near Classroom 2E. After Minerva McGonagall pulled Oliver Wood from Filius Flitwick's class to speak with him and Harry Potter about his joining the Gryffindor Quidditch team, she led them to this classroom, where Peeves was writing rude words on the blackboard. McGonagall told him to leave them, and he threw the chalk in the bin and left, cursing.
