hate to say it, but i reckon snapes a good guy. gut feeling i guess.
but im kinda thinking why snapes parents passed down a 6th year potions book to snape, for him to use, when ron's family, being poor (or once being poor), didn't even pass down a 6th year potions book to ron (and note, bill, percy, and charlie, both finished at hogwarts i think, and then his parents as well, so there's gotta be atlesat 1 book lyin around somehwere) ?
because obvioiously snapes mother had to pass the book down to snape to make it 50 years old and for snape to be the hbp, because harry thought it was his dad, but it couldn't be since it was 50 years old. so yeah. just thinking its kinda weird.. :/
