Despite Barney, Gomer, and Otis's shenanigans, the fact is that a man who Andy shot and who went to prison is back. He is an unknown quantity. That tension works really well. We don't know what to expect nor does Andy. The three idiots keep the comedy up. Gomer has no clue about the danger of the gun he is holding, and Otis's willingness to quit is great. Really liked this.
