What would the main character be likely to do if s/he visited your classroom?

I have just read finished "Scorpia Rising" written by Anthony Horowitz, which is about a teenage boy being recruited against his will into the world of espionage and is sent on a mission again. However, the mastermind of the criminal operation Alex is sent to uncover is Scorpia, which is a criminal organisation which was considerably successful until the arrival of Alex. They, needless to say, wanted to get revenge, as he had uncovered 2 of their operations, and survived an attack by a sniper sent by them. In addition, he feels tired as he has been sent on missions for countless of times, and it took up nearly a whole year. As such, he is forced to keep quiet about what he is doing.

What if Alex were to step into our classroom? I guess he would be very shy as he has constantly has to lie to his old friends at school when he was away for missions. In addition, he would also need help in studies as he was on missions. He would most likely sit at a corner and not talk to anyone. However, he would be very friendly and respond politely if one greeted him. Though he is shy and friendly most of the time, he would definitely help people he sees in need. On one occasion, a sniper miraculously positioned himself on the roof opposite the school and "tried" to take a shot at him. However, Alex managed to defend his good friend by pushing him down to the floor, out of range from the bullets.

Alex is now fifteen years old, and he has ,fortunately, left the world of espionage for good. He is also an expert in martial arts. He hopes to be just a normal boy, to go for his examinations, and to behave like a normal boy. However, he has recently suffered an emotional trauma as his housekeeper was killed by Scorpia. I hope he would be able to recover from it as time passes, and leave at last free from the world of espionage which had been manipulating his childhood from the start
