It's a creative way to try and make a buck, but I don't think Ben Thompson or Ford & Gina would care if it is Ben's baby. They would surely be glad to take care of her if it is. It doesn't make any sense.
You're right, but why would LB be going through all this if there was even a doubt? I don't care whose baby it is either. I'd just feel sorry for LB after this if the baby wasn't his. Seems almost cruel.
