Mac and Flack are also instrumental in ending a hostage situation involving a deaf young man holding his baby daughter and his murdered girlfriend's mother at gunpoint in their car. While Mac talks to the young man, Flack sneaks up on the other side of the car and slips the baby out of the vehicle through the driver's side window. As soon as the child is secure, Mac is able to safely disarm the young man without anyone getting injured. The baby is then returned to the custody of her grateful grandparents (episode 3.12 "Silent Night").
