McGonagall's Office is in a lot of School of Battle episodes. It was first seen in the episode "The Wand" where Mr. Winkler took the wand from. Her office is where the wand was hidden. The key was hidden in a Baloni sandwich in her fridge. Her office is a replica of the Apparation Classroom. But in her office she has a TV with an Xbox, cable, and a Video Chat Camera. She also has a big window on the side. McGonagall taught many spells in her office including Disorient. McGonagall's Office was then seen in "The Disorient Charm" and then it was again seen in "The Book". She has one rockin office I can tell you that!
