Mistake in the book
In the Chapter,"The Prince's Tale",Rowling has shown Snape's various roles,one of which includes him talking to Dumbeldore's portrait.
If you read the book correctly,you'll find that there is a scene wherein Dumbeldore's portrait asks Snape to give the correct timing of Harry's departure from Privet Drive.What we must note over here is,that the school year had not yet begun.Also,Snape was accussed of murdering Dumbledore.The Ministry was still under Rufus Scrimgeour's command.Which means that they were after Snape.
So,the quetsion over here is-How did Snape enter Hogwarts ?
If he did,how did he get into the Headmaster's cabin ? Did Hagrid help him,seeing as he is the keeper of the keys ?
This was well before Snape became the Headmaster.
