Tacitus666, AKA Arkaine (as he is often known) is the New Zealand equivalent of a cynical logic-buster. In other words, he is always on a different train of thought to his peers, and though this may seemingly indicate mental problems, this couldn't be further from the truth.
Unfortunately it often seems like he is mentally unstable, due to his complete inability to comprehend extremely complicated maths equations. Also, he can pretend to "stutter and look like an idiot" at the drop of a hat. Many times he has been unable to counter arguments headed directly toward him, yet in the hours or even weeks following these arguments, he has been known to 'suddenly' realize the perfect comeback and responses to his opposing peers. Put simply, it drives him completely mad.
To this end, Arkaine can often be found putting himself in a cocky demeanour, boldly challenging 14-year-olds to a game of Magic: The Gathering, only to lose the match as well as a sizable chunk of his ego, which is subject to regeneration. He can also be found saying what he thinks to be the perfect comeback to any insult, only to realize that he has messed up his words and said it completely and horribly wrong, again making him look like an idiot.
He can often be recognized in his trademark black brandless cap, black parting shirt, black shoes, and an uncomfortable look on his face. It is not entirely uncommon to see him carrying up to TWELVE different items of food as he makes his walk from the school canteen to the spot where he and his 'friends' and 'acquaintances' hang out, whereupon he eats it all as the others look on with an unsurprised look on their faces. Contrary to all reports, Arkaine is indeed the only skinny person in his household.
