That would be my guess, as well. They've ruled out Screech and Mong as being totally unsuitable as parents. It may also be a factor that J&B have absolutely refused to be returned to Casa Shithole. I also have a feeling that our two dipshits have flown the coop to Screech's Mom's house to help with her Dad. Lorraine probably gave them an ultimatum if they want to keep being pulled by her tugboat.Because they're already certain they're not going to give custody to the other parent so they're making sure the likely candidate is mentally sound?
Just my laymen's opinion.
