Victor felt the hair on the back of his neck stand up as something clattered to his left, his gaze went to Mino's shop window thinking perhaps the alchemist was taking out his garbage for the evening. He was about to speak when he heard the same sound, but from the opposite side of the street. 

Victor let out a breath and his palm came to life with the dim glow of one of the few battle spells the boy knew, it was his pride and joy, based off the simple frostbolt spell, his variation looked much like its predecessor, a spike of ice about the length of ones arm that could be fired at about the speed of an arrow, Victor had added a nasty surprise to this spell for when it hit it's target the spell would explode and send icy shrapnel into it's victim. 

The spell could easily be blocked by any ward as it was still just a variation of a Magus-School level spell, but still it was likely to deter an attempted mugging which at this point Victor believed was about to happen as multiple sounds meant multiple attackers.

While obviously spooked Victor kept his pace walking as if he hadn't noticed the sounds, giving his attackers one more chance to turn back from their foolish venture. If they did attack he would hit them with his FrostBolt and if they were simple humans then they would die there in that dim street, however if they were Mage's Victor knew he was well in over his head. At the same pace he had started with Victor continued walking towards home.
