This episode has some of Lucas's best acting! There is a huge pink elephant in the seaver house! At time in history, an unmarried man did not visit a married female without a third adult being present. Lucas was there for a reason not talked about in *im*polite company. Cora was trying to be the hostess and pretend everything was normal.
I thought it would be neat to have a place to discuss "The Rifleman" episodes. If there is an episode you wish to discuss in length, please feel free to post it here.
