However, he slowly opens up with encouragement from Your Character and her friends, to the point he becomes comfortable discussing his family and his sexuality with them.
Speaking of family, Zig is fiercely protective of his family. Considering he has four sisters and was raised solely by his mother, Zig has grown up surrounded by strong female role models and has great respect for the women in his life. In fact, he defended his sister Marie when her abusive ex-boyfriend marched into their old home and tried to assault her, leading to Zig beating him to a pulp and receiving a community service order for doing so. This displays just how far Zig is willing to go to protect the people he loves.
From about the time of The Sophomore, Book 1, Zig has shown signs of becoming mellowed as he is accepted into Hartfeld University via the Second Chance Scholarship, which was accepted by Dean Stafford after a proposal by Student Body President Chris Powell with the help of Zig and Your Character. Despite this, Zig does often show signs of frustration about how he is treated by those who know of his background, but he does his best to improve on his temper.
