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 do n'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 . " 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
