She's married in real life and as you could tell in the episode she was SUPER pregnant when it was filmed. Thing is, this story has always been about the people. Never really about the walkers. The whole idea being that even in the zombie apocalypse the true monsters are still the living. I actually skip through the episodes. I never watch a full one. Comic is still better and it's now in the war with "The Whisperers" people who literally wear the faces of the walkers and hide out with them in plain sight.
