The Walking Dead (TV series)
Only one person is left in the CDC. This person is Dr. Edwin Jenner. Everyone else has either left or killed themselves. Dr. Jenner tells the group that his research into the infection has not led to a cure. The CDC building is not the safe place the group thought it would be. The next day, the safety protocols are started when there is not enough fuel for the generators. An explosion will destroy the CDC. The explosion is to stop the escape of any deadly diseases in the CDC. Dr. Jenner tells the group that the French may have found a cure. He thinks this is possible since they survived the longest in their labs. Dr. Jenner choses to stay in the CDC and die in the explosion. A member of the group, Andrea, tries to stay as well. Her sister Amy had just died and Andrea did not want to live anymore.  Dale stays with her. He tells her that if she does not leave, he will not leave also. To stop him from dying, Andrea choses to leave with the group. Before the group leaves, Dr. Jenner whispers something into Rick's ear.  The group leave just as the CDC explodes.
