These rules are what keep rivaling gangs at bay, but as in any game if you don't follow the rules you called get penalized or in this case killed. The main code is based on loyalty, loyalty to your family, friends and your self.

This makes her anxious and weary because she knows that Tony has mucked around in the past so she asks Tony if he called get a vasectomy. Tony totally disagrees with the idea and asks her to forget about it. This angers her because she doe not want a bastard child brought into the family. Later in the episode Tony agrees to the vasectomy but his wife doesn't. She just wants him to be loyal to her and maybe have another child.
