Afton surveyed Malfoy expressionlessly. He knew this was Morag's boyfriend, but more so he knew the boy as Professor Malfoy's son. Afton was certainly in no rush, and he was not about to get into a petty name-calling argument outside the professor's office, which is what Malfoy's comment seemed calculated to cause.
"Would you like to go first?" Afton held out his hand to indicate the door. Besides, this way Malfoy would be indebted to him, or at the very least patronized. Malfoy's choice was to accept the patronization or to go second. Afton liked his position.
