At first, she had a tough time with Aaron and suffered a huge blow. She had always thought that she was carrying Giancarlo's child, only to find out it was actually Aaron's.
She didn't even know when she had conceived a child with Aaron. Later, Aaron told her that all the things she thought were with Giancarlo were actually with other men that Giancarlo had found.
She never even owned a single strand of Giancarlo's hair.
At first, he didn't realize this. He thought he had completely outsmarted Giancarlo, making him drive Jazmine away and causing the death of their child. Moreover, the child in Yoselin's womb wasn't Giancarlo's either, which would be a devastating blow to him.
As a result, it was only later that he realized something was wrong. After going back to investigate, he discovered that Giancarlo had already found another man to replace himself in sleeping with Yoselin.
