Yeah,Dobby . His death is one of the saddest moment in the book. Almost make me cry. I totally have no idea that Snape had a crush on Lily and they used to be friends too . Harry entering Snape's memory is one of my fave part in the book . I somehow guessed that Snape is a spy or someting but in love with Lily?Totally blew my mind away.Poor Snape .
