The night was long. Ella couldn’t sleep. But then she thought of something.
She spotted that Sam had a birthmark on the bottom of his foot, and Eric had one at the same place. She went to Sam’s room and inspected the birthmark closer. That’s when she noticed his birthmark and that of Mark were almost similar.

In the morning, she asked Eric if there was something he needed to share. He said he wanted to return Sam because he guessed he was his biological son. When he saw the birthmark he sh0cked.
The truth was that Eric had an affa:ir with some woman he met at a bar. He confirmed it was just a fling and a one time thing, but he che:ated when she was the most delicate and went though painful IVF’s broke Mia’s heart.
It was clear that Eric deplored breaking his wife’s trust, but che:ating on her was something Ella couldn’t accept that. She simply couldn’t live with Mark any longer.
Eric didn’t vanish out of his son’s life completely, but their connection was stricted to rare visits and birthday gifts sent through the mail.
Ella understood that she made the right decision for her and Sam. The moment she realized Eric was ready to abondon on his son in order to prevent his aff:air to be learned of.
