"I don't care if it's Justin Finch-Fletchley with the damned Choir, they aren't about to come down here and attack us!" I replied, levitating the cauldron and making my way carefully to the door. Narcissa had her wand out and took over levitating the cauldron for me, shooting it down the hallway towards the looters and followed it up with a Confringo hex. The blast undid the bubble-head charm on it, and I could hear bodies dropping like flies as I pulled Narcissa in from the doorway and slammed the door shut, charming it to seal entirely.
