Entertainment Weekly spoke with The Walking Dead Showrunner Scott Gimple about the development in detail.
Gimple and the writing team had the storyline in mind from the beginning because something's similar took place in the comic books.
"This was not a story that was sensational," he says. "We weren’t exploiting anything. It was something that was very much a part of Carol’s story and very much these girls’ story and very much a story of this world, and I felt that we had a very sensitive approach to it. No matter how extreme the end was, we weren’t just doing it for shock."
"To the emotional conclusion of the season. Both episodes are really big episodes," Gimple teases. "There are some insane things that happen. There are some tragic things that happen, There are some things that happen that are hopeful. And there is just some remarkably dark stuff."
