"Not for me," Kate replied immediately, lightly nudging his arm with her own. "I don't know that I realized it at the time you and I decided to try for a baby, but we pretty much gave up on going home then, don't you think?"
There was a small part of her that wondered if this baby could at all be the same as the one Lucifer had told her that she had at home, but Kate had resigned herself to never ask him. If the answer turned out to be no, it'd destroy her just as thoroughly as the idea of going home and given up this child.
And hadn't Lucifer told her that she was home and happy? So, in some way, her other child was loved and taken care of. It still tore her to pieces if she really stopped to think about it but she could accept it nonetheless.
