The Enemy Within - episode #5

Here's some background information on The Enemy Within...  Richard Matheson wrote the script and his original ending was even more provocative that the one filmed with Spock & Rand! As is well known, in the finished episode Spock hinted to Rand at the end that she might have liked some of the brutal Kirk's attentions and Rand acted like a team player in response, rather than slapping the Vulcan. Here's the original script:
It's beginning to look to me that they changed it to make Spock a bit of a villain so as not to make Rand appear like a lady really into S&M abuse and so on. Here's the site from where I sourced this: ENEMY WITHIN BACKGROUND MATERIAL

Finally, here's a link to a YouTube video which re-edits scenes from The Enemy Within into proper order:


It has also come to light that some scenes in the finished version of the episode were edited into a slightly wrong order. For example, I always thought there was something off about that scene where Kirk is told of the transporter problem and "if this should happen to a man..." and Kirk starts to say "Oh my G.." - the article link above and the YouTube video explain why it seems off.
