Mike said he would not kill Fredo untill the mother was dead. But when he said that the mother was not sick. There was no mention of her being ill. So how long would mike have waited to kill Fredo? What if the momther had lived another 20 years? Would Mike have waited? MAybe he thought the mother would live a long time and he would not have to kill Fredo. Am I right or did they mention the mother being sick and I just missed it. And she looked like she was in her 80's not 60's. I understand the timeline but they made her look really older then she was. I understand that back then most Italian women after losing there husbands kind of let themselves go and almost wanted to die but she looked pretty banged up.
