"Listen, Regulus. Mischief knows no rest." Sirius smirked and kept thinking, finally finding the right tube and pulling it free, but not yet handing it over. "Whose house are we at again? Malfoy, right?"

He pondered, almost dreamily. "Lucius does have that long, long, long hair." He sighed, then smiled at Regulus. He was hoping he could touch upon it. That hint of mischief inside his brother, that he always tried to bury so well.

"Don't you think his hair could be improved if there was just a bit of sparkle, to catch the eye?"
