Paper Towns: Q and his new attitude

I am almost halfway through Paper Towns by John Green and Q has changed drasticaly compared to the beginning. At the start of the book, Q is kind of quiet and shy. The thought of skipping school was completly ridiculous to old Q. But after Margo makes him go out for a night on the town and for her to never return, Q lets himself crawl out of his shell. He is constantly wondering about Margo, and he needs to find her. Q quickly becomes this rebelious kid who decides to skip school and drive an hour away from their hometown, to this abandoned mall where Margo said she was. He stopped being this small, weak science kid and because a tough, rebelious, can-break-doors-down-with-his-fist kid. Ever since Margo popped into Q's life, he completly changed. He became more passionate in life after that night with Margo. Before it, he was focused mainly on school and didn't really have a lot of fun in his life, but now he is searching for an adventure. And, of course, Margo.
