They don't just bring it up multiple times an episode..entire episodes revolve around the same god damn backstory that they keep shoving down our throats. Instead of allowing the viewer to make conclusions on their own, it's like the writers think they have to hold our hands and point at Daryl crying so we grasp that he had a shitty upbringing. This is just one blatantly obvious example of how shitty some of the writers are on the show. Like gato said there are thousands of other possibilities to write about, yet this show dumbs it wayyyy down. It's no surprise the writers in the first season either are no longer with the shower or have very limited power. To your point Carrol's character has progressed nicely, I just wish her freakin hair would grow out.
Why would you have to see the fire? You can hopefully use a little deductive reasoning, the smoke cloud was massive every time they showed it, clearly isn't some campfire a bunch of cannibals sittin around singing kumbaya...
I'm gonna spend time outside on sunday at 9pm? haha you are in the minority here defending the show...
