 The producers came up with a very interesting idea to keep their  viewers looking at the show during the hiatus between the first and  second seasons. In the first seasons final episode, the Marshalls  discover that for some reason they arent supposed to be there. Enik  later informs them that due to a time disturbance that they never  really arrived in the Land of the Lost and must go back in time and  relive the accident that brought them there. By going back in time,  they also would experience everything that happened to them up to  that point in a sort of time loop.
