He is unlike any other Slytherin.
    There is a saying in the Slytherin common room, "The little wizard who disobeys will be killed and then be eaten by the Night Stalker."
    Friend of the Shadows, the master of Assassination skills and weapons, the Night Stalker whom his enemies fear.
    The glory made him the pride of Slytherin.
    When the Dark Lord arrived, John emerged from the shadows,
    "Whoever comes, Whoever it is, I'll kill them. I'll kill them all !!!"
    With a Wand in his left hand and a sword in his right hand, he will give Death Eaters the hell they deserve!
