Land of the Lost1974

[The alien Enik has made a startling discovery about the temporal doorway that has led him and the Marshalls to this world]

Enik:
I cannot leave here. Nothing can leave here, unless an object of equal mass and temporal energy enters.

Will Marshall:
Well, that means we can't leave either, unless three other people come in.

Enik:
Yes, but there is more. You should not be here at all. Your presence here is the source of my problem. Look...

[Enik opens the time doorway onto a view of the Grand Canyon]

Will Marshall:
It's Earth! Enik, if I had a parachute I could jump through!

Enik:
Wait, there is more.

[Next Will sees himself, Rick, and Holly]

Will Marshall:
That's us, on the river!

Enik:
Pay attention now, this is the troubling part.

Will Marshall:
That's the rapids we were on.

[The time doorway replays - via stock footage of the show's title sequence - Rick, Will, and Holly being swallowed into a cavern by a monstrous earthquake, descending down underground rapids, and plunging down a monstrous waterfall - but Will notices an anomoly the audience cannot see]

Will Marshall:
Enik... where's the mist for the doorway?

Enik:
I do not know

[Will now realizes what Enik means by his earlier comments]

Will Marshall:
We... we were all killed. Weren't we.

Enik:
Obviously. You should not be here now.
