The other adoptions
I wasn't too terribly surprised that the movie made no reference to the other adoptions from that same agency that would subsequently be overturned once proof of its fraudulent practices came to light.
If the FBI was able to find Elena's birth-mother surely they were able to locate records on the rest. Doubtless some of those adoptions were several years old. But the protagonist never seems to face the question of not only making a decision to relinquish her baby, but all of the others as well.
& the husband ... what a sport!
After all of that I'd have said, "No more babies! We'll get dog."
