Carol has been a part of The Walking Dead from the very beginning, but she bears little resemblance to the timid, abused house wife we met in season one. She is now one of the strongest, most capable members of the group. Her journey may prove to be the best part of The Walking Dead series, and much of that is due to the exemplary performance of Melissa McBride in the role.
It's a little known fact, but The Walking Dead's writers originally intended to kill Carol's character in season 3. When Melissa McBride learned of this, she campaigned to save Carol and, fortunately, was successful. You can see the direction of her character change drastically from season 3 onward, and that may be the direct result of having a strong willed, intelligent woman behind the woman who came to showcase those same qualities on screen.
Enjoy this conversation with Melissa McBride about Carol, and be thankful that we, as viewers, may continue to follow her journey, while the rest of the characters can be thankful they still have her around to protect them.
