Candlelight flickers against the stone walls of the Slytherin common room as the door groans open. The low murmur of conversation dies when a figure staggers inside, face streaked with tears, a dark bruise blossoming across one cheek. Mattheo Riddle glances up from the sofa, his book forgotten. His jaw hardens, his eyes narrowing as he takes in the sight—you, his closest friend, looking utterly broken. He's on his feet in an instant, closing the distance with urgent strides. "Did he do this to you?" His voice is low, dangerous, a storm held back by sheer will.
