In this week’s PEOPLE cover story, a legal source tells PEOPLE that while the threat of time behind bars is there, Loughlin and Giannulli are most afraid for their daughters.

The source adds, “Lori is very afraid that her daughters will have to testify. That will traumatize them even more.”

For Loughlin, what matters most is the opinion of her daughters. “Yes, she can think about the public perception of her, but that’s nothing compared to what her daughters think of her,” the legal source explains.

Previously, a source detailed to PEOPLE how Loughlin and Giannulli “always wanted the best” for their daughters and oftenput pressure on their kids to succeed at school despite the fact that the girls did not appear to have an interest in academics.

“Olivia and Isabella’s personalities were always very different from their parents. They are average students. They have never been obsessed with school and didn’t seem to care that much,” the source said. “They attended school because their parents made them. Their focus was never about getting straight As.”

“It was always clear that it was the parents that pushed them to go to school,” the source continued. “Olivia always talks about her vlog. This is her passion. She never really understood why she needs to go to school.”
