Mia looked over her shoulder and saw a sour faced McGonagall coming over to them. Then behind her, Proffesor Slughorn appeared and she rolled her eyes. What was that fat man doing here? What did he care what the students got up to? She folded her arms and relaxed her face, whilst Albus was fuming and looked as if he were about to punch someone.
"Hello Proffesor, what brings you to the train?" Mia said with a smirk to the headmistress.
"Ah, Mia Black and her two friends Victoria and Jeff. What are you doing now?" Slughorn asked.
"Nothing. Just waiting to get back to school" Mia said with a shrug.
"LIAR! They've locked Rose in there!" Albus snapped, pointing at the toilet door, not realizing he still had his wand raised.
