Referring the newer episodes back to older ones is what I love about this show, and I'm really enjoying it. I was skeptical about how this half of the season would turn out, but it's heading in a good direction to me.
Right there with you.
My favorite part about this series is remembering back to who all these characters used to be and witnessing what they have become to survive in this world.
In particular, Andrew Lincoln does Rick's character evolution all the justice and then some that it deserves.
