From Harry Potter and the Order of the Phoenix
'Manners, Potter, or I'll have to give you a detention,' drawled Malfoy, whose sleek blond hair and pointed chin were just like his father's. 'You see, I, unlike you, have been made a prefect, which means that I, unlike you, have the power to hand out punishments.'
'Yeah,' said Harry, 'but you, unlike me, are a git, so get out and leave us alone.' (OP10)
'Tell me, how does it feel being second-best to Weasley, Potter?' he [Malfoy] asked.
'Shut up, Malfoy,' said Hermione sharply.
'I seem to have touched a nerve,' said Malfoy, smirking. 'Well, just watch yourself, Potter, because I'll be dogging your footsteps in case you step out of line.' (OP10)
Hermione: 'Malfoy was being absolutely foul to a first-year back there. I swear I'm going to report him, he's only had his badge three minutes and he's using it to bully people worse than ever… (OP10)
'Maybe,' said Malfoy in an undertone, so that only Harry could hear him, 'the stupid great oaf's got himself badly injured.'
