Law & Order: SVU Season 19 Episode 10 deals with the subject of mentally ill mothers and daughters.

When Rollins and Carisi are called to a special needs school to investigate an alleged rape of one student by another, Rollins gets a funny feeling about the alleged victim's mother. She confides in Benson, who is on a leave of absence following the Noah kidnapping debacle, that she thinks the mother might be poisoning her daughter. Warner confirms this, but the mother feigns innocence and claims to have taken her daughter from doctor to doctor to try to make her well.

Olivet determines that the mother is suffering from Munchausen's Syndrome by proxy. The mother seems to be untouchable, being released on her own recognizance and then let out on bail after she ignores an order of protection to try to take Mariel's IV out of her arm.

When Mariel kills her mother, Barba is forced to prosecute even though he feels the girl is a victim who snapped and not a cold blooded killer.

Meanwhile, Benson struggles to figure out what to do when Noah asks if Sheila is okay and wants to see her.
