<P> This episode marked the climax of the relationship between Maggie Greene and Glenn, in which they engage in sexual intercourse at a pharmacy . Writer Robert Kirkman insisted that it was important to view the storyline in a different perspective, explaining, "I don't think we wanted to turn that into some kind of steamy, pornographic sex romp ." "Cherokee Rose" marked a turning point in the character development of Daryl Dixon . It contains a monologue that references the cherokee rose and its association to the Trail of Tears . The scene was devised and written by Evan Rielly . "I was actually on set during the filming of that," stated Kirkman . "Almost every actor in the cast showed up, because they absolutely loved that scene and they wanted to see Melissa and Norman's portrayal of it as it unfolded ." </P> <P> The episode contains a scene in which the survivors pull a bloated walker out of a well in order to prevent contamination of the water . Such attempts prove to be unsuccessful, as all of the water retention severs the walker in half . Greg Nicotero, the special effects director for The Walking Dead, collaborated with KNB Efx Group to produce the sequence . Nicotero received a phone call from staff members of the company two hours after leaving production offices . They devised and expressed plans of creating a scenario in which a walker falls into a well . Nicotero worked with KNB Efx Group in several other films in the past . "One of the things we've noticed--looking at some morgue research and cadaver research--is that everything gets really swollen," he articulated . "The liquid saturates the skin so much that it swells up, and the skin starts to split . That was one of the things that we really wanted to play up ." A costume was sculpted using a body and a head cast . It was composed of three layers; a thin skin - like substance covers the exterior of the suit, followed by a layer of silicone and a layer of foam in the costume's center . A mask that was previously utilized in the action horror film Grindhouse (2007) was used as part of the costume . Nicotero inserted water balloons between the silicone and foam layering . He explained that as the performer begins to move, the liquid transfers from one side of the costume to another . Nicotero added: "If we made it out of foam latex, it would've been stiff . But we used silicone that was heavily plasticized--which means that the silicone was really soft ." The suit weighed approximately sixty pounds . </P> <P> Brian Hilliard, a member of the KNB Efx Group, was chosen by producers as the walker . Hilliard was favored in lieu of another actor, who fell ill shortly after being cast . In his interview with Entertainment Weekly, Greg Nicotero explained why he chose Hilliard for the part: </P> <P> I needed somebody who could perform, and who also had a lot of endurance, because we were shooting in Atlanta at the end of July . Silicone doesn't have cell structure, like foam does . It doesn't breathe . So Brian was basically encased in a sixty - pound wet - suit . Every part of his body was covered . He had facial prosthetics, hands, full legs, feet . It was all glued down . It wasn't like we could take him out between takes . He was in . </P>
