text: Over the next several months , Lori finds that both Rick and Carl have grown distant from her . Lori is near the end of her pregnancy as the group finds an abandoned prison they decide to clear out for their own . They deal with roaming walkers as well as five living prisoners , two who quickly fall into line with the group , but the others they are forced to kill , while Rick leaves the fifth , Andrew , outside in a pack of walkers , though unknown to them , Andrew manages to escape . Lori fears that the baby may have rotated in her womb to make normal childbirth impossible , and has the group practice Caesarean section on dispatched walkers . Sometime later , Andrew lures a group of walkers back to the prison to get his revenge . The group is forced to scatter as the walkers flood ; the fright causes Lori to enter into labor , and she , Carl , and Maggie take shelter in a boiler room . Lori 's fears are affirmed about the birth , and she instructs Maggie to perform an improvised Cesarean section on her , knowing that without painkillers or anesthetic , this will likely be fatal for her . She says her goodbyes to Carl before Maggie starts . Lori 's daughter is recovered alive , but as she expected , Lori succumbs to the procedure . Carl insists on being the one to put down Lori before she can reanimate . Maggie and Carl take the baby outside once the walkers have been cleared , and Rick , on seeing the child but not Lori , breaks down .

Rick starts having hallucinations of Lori and other survivors that had previously died , leading to him struggling to keep leadership of the group .
