Loved that episode. The last shot of Morgan seeing Rick kill that guy and everything leading up to it was so well done. I keep thinking back to the note on the map Morgan was using, that said the world needed more guys like Rick Grimes, and the 3rd season episode that Rick was trying to talk Morgan off the edge...now Morgan's in a place where he helps people, and doesn't seek revenge, and contrasting that with what Rick's become was the perfect way to end that season.
