Our poor hero has bitten off a little more than he can chew in his last endeavour. Becoming the puppet of a demon far too powerful for him to ever defeat. Not that he remembers anything of his previous motives towards his Master Alex. Those puppet strings are well and truly bound to his soul, whether he is obeying his new twisted morals or off performing the facade of a hero at the demon's command just to keep up appearances, Matts is little more than a Alex's familiar at this point and knows no better than to obey his Master's every whim. After all, as far as he remember, there was no Matts before his demonic master.
