Dr. Smith's greed -- or gluttony -- gets him in the soup again. The scene around the dinner table with the protein pills had an air of improvisation and fun about it. I liked that a lot of this episode takes place at night; it suits the b&w cinematography of this first season. The conflict was resolved a bit too simply for my taste, but at least the doggies didn't get hurt.
The robut is really coming into his own with these past few episodes; really becoming more part of the cast than just a piece of equipment or plot device. Fun banter with Dr. Smith.
I imagine Smith and the robut bought a house together once they got back to Earth.
