His first touch of magic

severus discovers his magic abbility, he was mucking around in ollivanders whilst waiting for his mother to get her wand checked up on, and he picks up a random wand pretending to be Ned Kelly with a gun (i dunno, i think that Ned Kelly was sev's childhood hero ') and the wand emits the colour of his aura. his mums all like "wow!" and his dad is all like "shit!"
