Minerva had come to the dungeon to go to the potion lab, but found it locked. That was the second year in a row she had come to find it locked .She was surprised to see it locked this term, because it had taken her longer to get there. Someone had to have been in there by now she thought. Maybe, Professor Lafay had it locked for a reason. She went to the professor's door and knocked. She had been to the this door the last three terms, and did not fear it as much anymore.
