We find out what the Potters did for a living, which was closely related to why Voldemort was after them...and probably how they got all that gold for Harry, too!
Professor Snape will fall in love (wow...maybe he'll be nice to the Gryffindors...no way that's too scary) and redeem himself!
Hermione will become Head Girl (::yawns deeply:: we all knew this was coming didn't we?)
We will learn something HUGE about Lily Potter!! (OOOH I CAN'T WAIT!!!!!!!!)
NOTE: Some believe that Lily Potter...(get ready)...was a DEATH EATER!! Oh no, not our wonderful sweet loving caring motherly Lily Potter! How could she be a Death Eater??!! Of all the utterly disgusting things she could be, it has to be that?? I don't believe it. That would really ruin things for Harry. I mean...imagine thinking your parents were these wonderful people that didn't deserve to die, then you find out that your mother went out and killed and tortured people? UGH. If that happens, I will be extremely disappointed in J.K. Rowling.
Reasons Why I Don't Believe It:
1) Lily was a Gryffindor. Gryffindors never grow up to be like that.
CONTRADICTION: Pettigrew was a Gryffindor, wasn't he? There's still a lot of mystery in that man.
2)For some reason I imagine James Potter as a good-girl kinda guy, lol.
3) Surely Voldemort would have said something to Harry on the night of the third task. He would know a thought like that would torment him.
i also have the rumours list for possible couples which i intend to give out soon plus the second chapter of hp and the secret horcrux!!
