I Have A Theory

Or rather speculation (whatever the right word is)...

After reading Harry Porter and The Order of The Phoenix,



and just recently finished reading Harry Porter and The Half-Blood Prince,



I think Snape is actually on Dumbledore's side. Ngeeee...

For those who have finished reading them all, please let me get away with my speculation. Therefore, the 'comment' is disabled. ;)

Oh no, no, no. I haven't read anything from the Wikipedia. I don't want to spoil it like I did before. ;)
