It has not been long since I first read the Harry Potter books and saw the movies, but from the first moment I saw Severus Snape, known only as the man talking to Professor Quirrel, I knew without a doubt that there was no one else who ever could have been Snape. He brought this character to life more vibrantly than I could ever have imagined or hoped for. Rest in peace Alan Rickman, and know that we will remember you, always.
Legilimens. "The mind is not a book, to be opened at will and examined at leisure. Thoughts are not etched on the inside of skulls, to be perused by any invader. The mind is a complex and many-layered thing... It is true, however, that those who have mastered Legilimency are able, under certain conditions, to delve into the minds of their victims and to interpret their findings correctly." —Severus Snape
