S03E05 The Space Primevals
Episode Overview
The primitive beings are actually under the influence of a computer named Protinius, which grants temporary advanced intelligence to the lead male to relay its intentions. In this episode, Don and Smith experience a brief moment of friendship when Smith saves Don from a pit. In a surprising twist, Don refers to him as "Doctor Smith" for the first time in ages. However, this newfound bond quickly fades, and they revert to their usual dynamic. While Smith has shown moments of selflessness and integrity before, he ultimately returns to his old ways, leaving their relationship unchanged.
