Jaco is a short boy with Polish roots, bright blue eyes and blond hair. There is a certain level of innocence with him, which is very appealing. Jaco can also appear a little bit stiff, which G. Duroy is working on. "I believe this stiffness is the result of a very good Catholic upbringing," George says. Based on Jaco's youthful experience with a local priest, George brought a group of boys to Vatican City and filmed them meeting the Pope. It was actually Jaco's second papal visit; that's how protypical a Catholic upbringing he has received. "He is doing his best to shed his inhibitions," George says. Jaco is quite pleasant and likable and brings good energy to those around him.
