Days of our Lives question?

I answered this in a previous post but here goes: We all know that Stefano would ask for a DNA test so I think in the back of her mind, Nicole was determined to get Sami & EJ's baby to be able to do just that. The doctor agreed to her crazy schemes 'cos she was blackmailing him. She would tell Stefano what he did (cover up her miscarraige) if he didn't help her.
