He pointed his index finger towards the room's second floor landing and from afar they could still decipher a candle's light slowly wavering out although barely. They both shared a knowing grin, holding out their own bag full of different coloured Muggle permanent markers for the other to see.
"Make sure to scribble down James' name all over his face." chuckled Valerie, picturing the horrifed expression Scorpius would soon have on when he'd wake up to find his face full of his siblings' markings and drawings. Damian gave out another snicker on her right side.
"And dicks," he said as he slowly made his way to the ancient staircase. "Never forget to draw dicks all over a sleeping person's face."
