Star Trek episode "The Immunity Syndrome"

"The Immuity Syndrome"

Season 2, episode 18.

The Enterprise battles a giant space amoeba!

Spock "felt" the death of the 400 Vulcans on the Intrepid just like Obi-Wan Kenobi felt the deaths on the planet Alderaan.

How often do they come across "something I've never seen." Answer: every episode. They have no idea what it is but they go in anyway, even knowing that the Intrepid was destroyed by it. They figure out a way to destroy it. Just another "Thing-in-space-we-have-to-destroy" episode.

SIDEBAR: "Probe will hit in 7.3 seconds." It takes longer to say the "point 3" then the "point 3" lasts, doesn't it? Then it is said again: "contact in 18.3 seconds." I know they are trying to be anally scientific like when Spock computes ETA at something like 5.2 hours. But that's okay because "point 2" hours is appreciable time. "Point 3" seconds is not. You can't even see the "point 3" as it rolls on by the chrometer.

SIDEBAR 2: Mr. Kyle was a helmsman in Sulu's place--how many episodes was Kyle in? I looked him up at StarTrek.com and it says later on "Twenty years later he was a commander and communications officer on the U.S.S. Reliant."

Season one, episode 29 (remember, this numbering is from the CBS.com website I am watching them on)
