Episode premise:
Kivas Fajo is determined to add the unique Data to his prized collection of one-of-a-kind artefacts and, staging Data’s apparent death, he imprisons him aboard his ship.
We know that Data is later logically coerced to lie in “Clues” to protect the crew, but this appears to be a decision all his own. Or did he not in fact actually fire the weapon?
Basically the same thing with Vulcans. Vulcans show their emotions all the time, it’s just almost always mild irritation and impatience.
