Just as a "Devil's Advocate" question, why would she lose custody of her children? Both of the Fathers are dead. That leaves Grandparents of JJ. What standing do they really have? Grandparents rights for visitation? Pretty nonexistent.
Idaho law on Grandparents rights
"The court may award visitation rights if visitation is in the child's best interest. Adoption cuts off all visitation rights of grandparents."
Grandparents' Rights in Idaho
Which means, because JJ is adopted, that cut off all visitation rights of Grandparents.
Lori doesn't even have to show up, they literally have no real standing. Sadly.
