At 1:23 on the DVD there is
a scene of Grumpy fighting Spike (or another Triceratops). I believe
this scene is actually from Wah Chang's earlier short film
Dinosaurs: The Terrible Lizards.
When the sun fails to rise, Rick and Holly remark
that the last time something like this happened, time stopped and
the sun wouldn't set when a crystal blew out in the clock pylon.
This occurred in "The Longest Day".
At 15:26 on the DVD, you
can see that Rick and Enik have stepped off the surface of the High
Bluff exterior set and onto the studio floor.
There are strange
background sounds in the Library of Skulls. They almost sound like
distorted voices of humans in pain! Is it the telepathic wah of the
Altrusian skulls? Listen:
This is the first time we hear Enik "speaking" in
the hissing sound of the Sleestak (when he calls the Sleestak guards
away from the second clock pylon).
At the end of the episode, we see that Rick has
removed the keys from the two clock pylons. Do the Marshalls also go
back and remove the keys from the other pylons? Were the keys still
in the cave at High Bluff when the quake struck and buried it in
"After-Shock" (leaving the pylons unopenable)?
