What was the saddest scene for you?

(I will start) Imo in season 3 when Rick meets Morgan for the first time in a year just broke me. I don't really know why this scene tops any character death for me but its probably because how much Morgan thinks of what the world has become and refuses help from Rick when he offers him to come with him. You can see how much Morgan has given up and how mentally insane he has become in this scene especially when Rick leaves the town and you can see him burning walker bodies.
