The door to the parlour was open, and as he passed he could see the back of what could only be Professor Snape, dressed in his voluminous black robes as usual, with his arms around Draco in a comforting embrace. Draco's cheek was resting on Snape's shoulder and his eyes were closed. Harry had never seen his face so unguarded, nor ever looking so unutterably sad. He hurried past to retreat to his room, glad at least that Snape was there to look after Draco for a while until they could get the whole mess sorted out.
