Millicent had come outside for some more fresh air, it had gotten much nice and being stuck in the castle these days was making her antsy to finish things up. She had been going one way, when she heard the familiar sound of rocks being blasted. The last time she heard that noise, it was Blaise and he had mentioned being out there another time. She was starting to see a pattern or at least that something was not right with him.
As she came around the corner she watched him blast a few more before pulling out her wand. She wasn't going to hex him to get his attention, instead she waited until she could tell the rock he planned to blast next and then used the most simple of spells to make it move as she leaned against the wall. "Locomotor Rock..."
Though she made sure not to move the rock towards her, the last thing she wanted to do was get blasted herself.
