Hindsight
In this unique episode, events leading up to Christmas are shown in reverse chronological order. Kovac's troubled life turns tragic when he gets into a car accident on an icy road--and his passenger, young medical student Erin Harkins (recurring guest star Leslie Bibb), is seriously hurt. Earlier, Kovac struggles to help a young man, Rick (Michael Ealy - "Barbershop"), fight for life as his condition worsens unexpectedly. Also, Abby and the emergency room staff attend to a pair of belligerent "elves" and a young female hockey player, Jane (Brittney Lee Harvey) with a head wound.
