The Eldest Pine Sibling

Y/n Pine is the eldest sibling of Mabel and Dipper Pine; he used to be a good kid. A and B student, Captain of the Baseball team, and even had a Scholarship but one day...Something changed. Y/n became a violent and destructive student out of the blue, falling all his classes and causing fights. He would go on being expelled from school to school while gaining a criminal record. To avoid prison, Y/n goes with his siblings to visit their Great Uncle for the summer and can not be arrested for anything!
