Goof: When Goren looks at the son's writing sample at the hospital (the one with the picture of the dinosaur), it is written very neatly and clearly. Later, when he looks at the same piece of paper, the handwriting is much different. The second version has childish handwriting that uses all of the lines at the bottom of the page.
Robert Goren: I see why you're not angry at her. Because she's a reflection of everything that you've done to her.
Paul Whitlock: I did nothing but help her.
Robert Goren: No, you terrorized her! You got kicked around at work, you came home, and you crushed her.
Paul Whitlock: I never laid a hand on her!
Robert Goren: You didn't have to!
Alex Eames: I don't know about you, but that guy's starting to stick in my craw.

This episode appears to be ripped from the headlines of the Andrea Yates case. In 2001 Yates, who many doctors believe suffered from a severe case of post-partum psychosis, drowned all five of her children in the bathtub before calling police to tell them what she had done. Yates was found guilty on two charges of capital murder. When questioned as to her reason for killing her children, Yates gave the reason that they were still innocent and would burn in Hell if she did not kill them.
The title of this episode, "Magnificat," refers to the prayer that Mary gave upon learning from the angel Gabriel that she would be the mother of the son of God. Also known as the "Canticle of Mary," the first line of the Latin prayer is Magnificat anima mea Dominum (My soul doth magnify the Lord). Magnificat means "magnifies".
