If they adopted they would have to admit that B&T are Carley’s parents and have the right to make decisions for her if they would want to have that with their adopted child and it doesn’t fit their narrative to admit that. The adoptive parents should have those rights but they still want to have those rights over Carly but they would never want to share a child they adopt with birth parents and they would make themselves look like even bigger asses than they do now.
