They were at Hogsmeade, and they ran into a little boy.
He had messy brown hair and big blue eyes. Daphne thought he was just adorable.
But Blaise smirked because he saw him for what he was.
"Come on Daph, he's a rogue… he'll steal your money."
And sure enough, the little boy hugged an elder lady and slipped his grubby hand into her pocket, producing a bulging bag of galleons.
Daphne managed to find plenty of reasons why the little boy would do such a thing, of course.
