This being the third episode, we already see the Robot falling out of Dr Smith's good graces. It's interesting, how the concept apparently changed within the first few episodes of the show. At first, Dr Smith and the Robot were not part of the show. When these two characters were introduced, it was Smith and the Robot against everyone else. Very shortly, the Robot started to move away from Smith, and towards the Robinsons. This episode also marked the introduction of the Bloop (although the Bloop did appear in the unaired pilot episode). Also curious is how Penny first referred to the Bloop as "him." Two minutes later, she says: "I'm going to call you Debbie." Penny always was a little genius, wasn't she? The humorous exchanges between Smith and the Robot were great (as well as when Smith tries to convince Prof Robinson and Major West of his sudden "reformation."
