I just had this idea.
I'm thinking that maybe Ephram would have decided that the child's best interest was to be with a family that would raise him, and be there for him in ways that Madison and Ephram could not. But have an open adoption. Ephram would get updates here and there.
I mean, imagine Ephram getting the mail, so excited to show Andy the newest picture of his son! It would change everything completely.
Ephram never said he wanted the baby, he just wanted to get to know him, and maybe one day, eighteen years in the future, the child...if he wants...can find Ephram and they can finally meet...father and son.
That's my take on it
