Agatha Ripp - S2-E8
Audio problem: When Christian is returning to the office and sees a crowd of people outside hoping to see Agatha (who they believe has the stigmata of Jesus Christ), he runs into a couple with their infant. Christian asks if their baby is sick, and the couple shows him the backside of the infant where it has a vertebrae "tail", and they then ask him if they can see Agatha. During this sequence, we can hear loud crying, but various camera shots show the baby's face and she/she is not crying.
