The hidden door in the bookshelf at Spinner's End, the starcase and sleeping room - doesn't that remind anyone of Harry's accomodation at the Dursley's in PS?
Seriously, Snape wouldn't have that installed for Wormtail only.
And what is it with Snape that he called Lily a Mudblood while he himself is one? How... stupid?
And how come he already knew so many hexes and whatnot when he came to Hogwarts? The Hermione of his generation? ;)
Why didn't we hear anything about Snape's Patronus so far? Can he create one? And if so - does anyone doubt it will be Dumbledore?
And about the Rumour section on JKR's homepage - about the rumour of Snape being Luna's father:
Why did JRK anser that no, Snape doesn't have a daughter? Does that mean he has/had a son or did she just want to keep us occupied/wondering?
