Answer:
Antigone is very loyal to her family, She disobeys Creon's order and buried her brother Polynieces, Antigone and her sister Ismene are both different because while Antigone values family loyalty, Ismene obeys law and afraid of punishment. i will explain further below.
Step-by-step explanation:
Antigone proposes that they disobey the decree by Creon, Ismene replied by saying "What can your meaning be?" Ismene tells her sister that the burial is forbidden in Thebes but Antigone loyal to family, believes that her brother deserved to be buried although he betrayed the state she responded to Ismene by saying "I will do my part.. to a brother. false to him i will never be found".
After Antigone had buried her brother, Ismene in trying to become friends with her sister again, declares herself to Creon that she wishes to share in the punishment and suffering with her sister but Antigone rejects the offer. All these connect to the theme of family and loyalty.
