Dorothy had enough of Jack and his ways. Putting up with her husband was already one hard task and then she had been keeping Beth captive. "I didn't fail you. I did everything I could to set you up to be successful and to be better than your father. You failed yourself."
"I stayed with your father because I already had you and knew what the future awaited you as his heir. I was not going to leave and have him get someone else pregnant to let them convince him to make someone else his heir. I did not help make something of this family for another woman to reap the benefits."
"You didn't need to stay because of me. That's an excuse that you use," Jack replied.
Jack knew he would have been well without his mother living here. His father loved him so regardless of who else walked through the front doors, he would always inherit everything.
