Many changes happened after the incident of Fleur Ash's sudden departure, first and foremost was that Crey left his dorm to shift his longings to the working lab and warehouse of the Professor. Everyone knew about his sudden 'moving', but neither Professor nor Major Moy asked or inquired anything from him. They let him do anything he pleased like they didn't care about his decision.
With the annual tournament appearing right around the corner, each and every Order was busy making preparations. For this reason, Head Professors like Major Moy were busier than ever.
It seemed like due to this hubbub of tournament Academy had unanimously chosen to forget about the recent assassination. And using this tournament, they were trying to regain the spirits of everyone back. But to Crey, the tournament was not even on the last in his list of worries.
