The twelfth season of the American fictional drama television series ER first aired on NBC on September 22, 2005, and concluded on May 18, 2006. It consists of 22 episodes.

Plot

Kovač and Abby become the main central characters and their relationship slowly starts to get back on track as they deal with her unexpected pregnancy. A new nurse manager causes friction among the staff; following a successful operation, Weaver no longer needs her cane. Pratt journeys to Africa to join Carter on a relief mission, while a face from Sam’s past leaves Abby and Kovač’s lives hanging in the balance. In addition to Darfur, geopolitics of the day get a strong spotlight due to the Iraq War.
