The scene with Ray and Robert in the car is arguably the best scene this show has ever done and it easily made up for the weak scenes prior to it, and the particularly lame ending after it. It was funny, it was emotional, it was honest and it was relatable.
This is a problem that all people will go through with their last remaining parent and it was just good for them to have a scene that lasted for about 10 minutes or so. It was unlike anything this show had done before, and was easily the highlight of this series. It made the episode for me.
