 Glenn and Maggie go off to the pharmacy to pick up additional medical supplies for Lori . Glenn , like Dale , expresses his opinion that the walkers need to be killed . Maggie is annoyed at his use of the word " walker " , saying that she knows those in the barn by their real names , as they were her friends and family . In the pharmacy , Maggie is attacked and nearly bitten while retrieving the supplies — she narrowly escapes after Glenn kills the walker . After returning to the farm , angry Maggie confronts Lori , who she blames for the near @-@ death of Glenn and her . After he intervenes , Maggie tells him that she does care about him and that the rest of the group do not respect him , only using him as " walker bait " . Glenn , however , tells Lori that he is her friend , and again urges her to tell Rick about the pregnancy . Unwilling to bring a child into a world that she sees as without joy , Lori takes the morning after pills Glenn gave her , but immediately goes away from the camp and throws them up . At the same time Rick enters the tent and finds the pills , then goes to find her . She ultimately confesses her previous affair with Shane ( Jon Bernthal ) to her husband , who reveals that he already knew .
