Carol is pretty much the prime example on how this world can change you. I love her character in the show.Great episode again and some really interesting character developments. Carol is badass (as we already knew) and she's good at playing the helpless victim before switching badass mode on. Also good to see that she does actually care about how many people she's killed and it is weighing on her mind as she wasn't always this way and must be a burden on her conscience to an extent. Yeah a lot of people deserved to be killed by her but bet she's wondering if they all "needed" to die & getting harder to blur the lines between "heroes" and "villains" in some scenarios.
In the comics she was completely different being not only in her 20s, but someone who just goes nuts after a break up and kills herself. Pretty much a throwaway.
I think this season is turning out to be the best yet to be honest. So many good episodes, and even if there has been filler, it hasn't been as obvious.
