Corrected entry: At the end of the episode the female child molester reveals that she has just learned that she's pregnant with her victim's child. However, earlier in the episode (several weeks prior in the episode's time span), she underwent surgery. A Pregnancy test is part of a standard pre-op workup for all women of child-bearing age. She would have learned about her pregnancy then. Obviously, this was altered for the "end of the episode" dramatic effect.
