You sense someone new

As you walk around the school grounds you feel a new presence in the building. You notify Zatanna to come to you as you enter the Gryffindor corridors you sneak closer to the mind until you hear whispers. You walk in to see Hermonie and Ron Weasley in a room as she is comforting him for what Ginny did. You then allow them to notice you at which point Ron spins his wand and you feel a tight squeeze around your throat. You fall to your knees, gasping for breath as Zatanna bursts into the room, chanting a incantation as Ron is tossed into the roof, with chains made of gryffin bones keeping him there. You catch your breath for a moment, before allowing Ron to fall to the floor, at which point you grab him by the throat and hold him into the air, demanding to know how he got in. He refuses to answer, so you give him over to Circe, for a more persuasive argument. You then drag Hermonie back to your quarters for a quick chat.
