They graduated and became policemen at King County Sheriff's Department. During that time, Rick had met Lori at a young age and married her shortly.

Afterward, Rick and Morgan go to the police station to arm themselves with weapons. Rick then heads to Atlanta, which Morgan had told him could be a safe place because of the CDC located there. Entering Atlanta, Rick finds out the hard way that Atlanta is anything but a safe place as it is filled with walkers. Rick soon finds himself trapped in a tank.

Rick is saved by group of survivors who lead him back to their group. It is there that he is reunited with his family again as well as his friend Shane. One night, when the group lets their guard down, they are attacked by a crowd of walkers. People die and the group is forced to move on. Rick decides that the group should head the CDC. At the CDC, Rick notices that there is someone still in there. After pleading, Rick and his group are allowed in. The group meets a scientist named Edwin Jenner who is working to find a cure. Finally, after much traveling, the group believes they have found a safe haven for themselves. However, their hopes are dashed when they learn that the CDC will self destruct when the power runs out.

This motivates Rick to try to persuade Hershel to allow his group to stay permanently.

Tensions between the two groups quickly rise when Glenn finds out that Hershel is hiding walkers in his barn. Shane, who is concerned for the group's safety, gathers up the group to shoot all the walkers in the barn, including a Sophia who had turned into a walker. Hershel is dismayed by the violence because those walkers were his family members. Hershel leaves the farm to drink at a bar. Rick and Glenn then go to the bar to bring him back. In the process, they get into a gunfight with another group. They escape, but are forced to bring along a prisoner. The group has a debate over whether to kill Randell the prisoner or not. Rick decides to execute Randell, but ultimately changes his mind when he sees Carl watching eagerly.

Shane, who is discontent with Rick's decision, takes the matter into his own hands and kills Randell in the woods. He then tells the group that Randell had escaped. Rick organizes a group to find Randell. Then he realizes that Shane had lied and was trying to lure Rick into a trap so he can kill him. The two have a stand off that ends with Rick killing Shane. The sounds of gunfire alert a nearby group of walkers that overrun the farm. Rick and his group along with Hershel and his family are forced to flee. However, Andrea is left behind. Finally away from the walkers, Rick declares that the group is no longer a democracy and seals his place as their leader.

The Governor, who is angry that Michonne had killed his walker daughter during Rick's visit to Woodbury, retaliates by sending soldiers and walkers to attack the prison. This attack snaps Rick back to his senses. After the Governor leaves, the group prepares themselves for another attack. Andrea, who heard of the attack and is staying at Woodbury, tries to make peace between the two groups. She fails and the two sides move closer to war.

As they leave, the Governor kills his men for losing the battle. Following the successful counterattack, Rick's group heads to Woodbury to invade the town. Inside the town, they find Andrea in a pool of blood after being bitten by a walker. She asks for Rick's gun and he lets her commit suicide.
