Question:
Who is the half blood prince, in the book "harry potter and the half blood prince?"?
Answers:
Read it and see.
Clue - it's Professor Snape.
That's why it's obvious Snape is not a bad guy, and is protecting Harry.
He obviously knows Harry has the book, and that's why he's suddenly doing well in potions, but he also wants Harry to learn some Dark Magic, and lots of the potions are Dark Side magic..
It all gets revealed later in the book.
