[spotting Harry and Ron, both disguised as Crabbe and Goyle]
Excuse me!
What are you doing down- [Harry nudges him; clears his throat and speaks more authoritatively] I mean, what are you doing down here?
I happen to be a school Prefect. You, on the other hand, have no business wandering the corridors this time of night. What are your names again?
[Rounding a corner]
Crabbe! Goyle! Where have you two been? Pigging out in the Great Hall all this time? [looks oddly at Harry, who is still wearing his glasses] Why are you wearing glasses?
Reading? [Harry nods yes; puzzled] I didn't know you could read. [Turns to Percy] And what are you doing down here, Weasley?
[sternly]
Mind your attitude, Malfoy.
[Malfoy just smirks and walks off; Harry and Ron follow him to the Slytherin common room.]
