SNAPE: Remarkable feat, don't you think? To enter Hogwarts Castle on one's own... -...completely undetected? DUMBLEDORE: Quite remarkable. SNAPE: Any theories on how he managed it? DUMBLEDORE: Many. Each as unlikely as the next. SNAPE: You may recall... ...prior to the start of term I expressed concerns... ...about your appointment of Professor-- Not a single professor inside this castle would help Sirius Black enter it. I'm quite convinced the castle is safe... ...and I'm more than willing to send the students to their houses. SNAPE: What about Potter? Should he be warned? DUMBLEDORE: Perhaps. But for now, let him sleep.
