From ‘first peck’, Tony Monelli was going to be leader. As his character built, his twin Terry naturally deferred to his brother. There was no doubt about their fraternal love, but in early arguments and rough and tumbles, and there were many, Tony almost always came out on top.
Nonetheless, they shared the limited things available to a poor Italian immigrant family, but inasmuch as Terry looked up to his twin, Tony felt a responsibility to look out for Terry. Tony was his protector.
The arrangement was great, until women came along. Hormones have a habit of messing things around.
