1. This episode oddly uses different terminology for a function of the ship, than any other episode.
'Directional controls' are referred to, instead of simply 'setting course'. A leftover from an early draft maybe?
2. He calls himself a fool. But who, or what, is actually the fool in this episode?
Correct!
As you say, LOKAI: What a fool I am, expecting help from someone like you. - Both of the citizens/inhabitants of Cheron for their racism.
3. I think I'm getting space sick...
Nice guess, but I was referring to the zooming in and out of the camera onto the red alert, used a couple of times in the episode. It sticks out, to me.
4. Let's all stand in a line, shall we.
Kirk, Spock, Chekhov and Uhura stand in a line and the camera pans past each of them, as they watch bridge controls being destroyed. As with the zoom in above, the director makes some creative camera decisions in an otherwise fairly tedious episode.
5. Interesting convenience going on here..
Here I refer to the door being ajar in the recreation room allowing Spock to conveniently eavesdrop.
6. Run, rabbit, run. - Correct! Lokai's evasion of Bele, especially at the end of the episode. I specifically meant the ending.
7. Neat or cheap? Henoch is correct. The invisible ship idea is neat, but production-wise saves on costs of building a new model.
8. There's a nice scene in this episode that is pure padding, but dramatically effective, and could easily have been used in other episodes. Correct! The auto-destruct scene.
9. Our mission is almost slap bang in the middle of this episode. The rest of the story is pure encounter. - Correct! Decontamination of the planet Ariannus.
10. This is probably one of the most 'talky' episodes there is. - Correct! Yep, lots of conversational scenes.
Well done! The bridge is yours!
