Dale, Daryl, Andrea, and Carol arrive at the Greene home and set up camp as Carl recovers. Since Shane is still injured and Rick is weak from blood loss, Daryl decides to search alone for Sophia. He does not find her but instead finds a Cherokee rose (a Native American symbol for the tears of mothers on the Trail of Tears) and gives it to Carol. Hershel takes Rick on a tour and tells him that he and his group should leave the property after Sophia is found and Carl heals. Rick begs Hershel to reconsider, and Hershel says he will consider letting them stay if they follow his rules. While Dale and T-Dog are retrieving water from a nearby well, they realize there is a walker inside. Since the survivors cannot kill it, as doing so might infect the water, they decide Glenn will act as bait to snare the walker, so that it can be removed from the well. They succeed in roping and raising the walker, but just as it is being pulled out of the well, its legs and internal organs break off and spill back into the well, thoroughly infecting the water. T-Dog then kills the walker. Maggie and Glenn head to a local pharmacy for supplies, where Maggie offers to have sex with Glenn and he accepts. Glenn retrieves a pregnancy test, requested by Lori, who later uses it and realizes she is pregnant.
