Headscratchers / Land of the Lost (1974)

• If Enik succeeds in warning the Sleestak's ancestors not to destroy their civilization, what will become of the Marshalls? Will their entire sojourn in the Land cease to have ever happened, leaving them back on Earth with no memory of the events? What about Cha-Ka, Taa, and Saa? Or will Enik's warning just create a separate, alternate universe where Altrusia never fell, leaving our familiar version of the Land intact? Or is Enik doomed to fail?

• Granted that Enik usually isn't quite friendly enough that you'd go asking him for help when it's not absolutely essential, but it still seems odd that the Marshalls never just ask him outright what the Land's origin is and how his people relate to it. Did the Altrusians create the Land, and if so, where did they come from before that? Conversely, if they're part of the artificial Land themselves, then who did make the Land? Humans or humanoids, as the later episodes imply? Then where (or when) are they from?
