Marcia’s take on the encounter with Paolo was that there weren’t many fit young men around her house and never had been... and sex wasn’t on her menu that often and she knew that Sofia was getting quite a lot... and with her husband Tony too!
Also, Sofia had said Paolo was sweet on Livia and was frustrated, waiting for the gift of her body. Marcia still didn’t like Livia and hated how she was keeping Sofia and her in the dark.
She delighted that she had had Paolo... and at the right time, she would certainly let Livia know!
