I think they are all mentally “challenged”. (I’m trying to be nice here!)
Have you heard that the kids don’t know who their REAL mothers are? They call numerous women “mother” so they couldn’t give them back to them anyway until they know who belongs to who.
I’ll bet they watched the kids interact with the “moms” and realized there was no way they were ever going to get the truth of identity, etc.
What a mess!
Hopefully, the six who chose ‘safe haven’ can shed some light on who belongs to who.
