What would happen if Alex Rider was revealed to his classmates and friends?

Third Person POV

Alex walked down the hall at school. His hair was slightly longer, and he had a new scar on his neck, curving round from under his ear to the nape of his neck. His beaten up rucksack hung of one shoulder. Alex passed a couple kissing against a graffitied wall. He made his way to his first lesson, History. As he walked, students whispered to each other.

Alex knew the things other students assumed about him and, although they hurt, he had learnt to ignore them.

Alex had already calculated all possible exit points and the amount of force it would take to smash one of the 3 windows that overlooked the dismal car park.

They piled into the classroom, shouting about homework and the latest football game. Alex sighed. He wished he go back to the times when his greatest worries were football, homework and insignificant movies.

Mr Garner shifted his weight from one foot to the other, drumming his fingers on his coffee cup. A frown marred his face. Alex took in the man's appearance. Scuffed brown shoes, creased trousers, a striped shirt (part of the collar stained with coffee) and a paper bookmark tucked into the man's back pocket.

Mr Garner cleared his throat before addressing the students seated before him. The shouts and laughter died down, nobody wanted to face Mr Garner's infamous wrath.

" Today in class we will learning about the history and reasoning behind War crimes, most specifically torture. Now, apparently this "triggers" people, but that is just a made up excuse. Everybody needs to sit through and view this lesson." Mr Garner said, contempt twisting his voice. Alex bolted upright in his hair. His face was scared and afraid. But, more than that, he looked angry
