Trivia, Quotes, Notes and Allusions
The episode has no scenes set on Moonbase Alpha and no characters other than the six on the Eagle.
The Eagle featured in this episode was carrying an extra-wide laboratory pod, yet whenever the characters used the door from the standard pod interior, it leads immediately outside. Also, the door to the pod as used by the characters was the wide door of a standard pod rather than the narrower door shown on the model of the laboratory pod.
The rocks could teleport Tony from the cave to the Eagle, yet they didn't seem to be able to do this to themselves so they wouldn't need other lifeforms to carry them to water.
As Eagle 4 lifts off under the rock's control, one shot of it in mid air showed a standard Eagle, not the "specially adapted laboratory section" it has at all other times.
