Naomi knows her husband well. Only a day after Joshua kicked Barnabas out of his life, he's declaring that both his children are precious to him.
I felt real sympathy for Abigail, as she told Joshua that her hair ribbon had been stolen so that the witch could cast a spell on her. She looked honestly scared, and we know that she was correct about the reason for the theft of the ribbon. I think this is as warm as I ever feel towards Abigail.
And I felt for Barnabas, too. He originally agreed to marry Angelique if she would save Sarah, and now he has been explicitly told that Sarah can't be part of his life.
