After Trek Cadet Training episodes 3 and Chaos on the Bridge review

We continue with our Cadet Training episodes from After Trek. This week we will take a look at TOS episode "The Devil in the Dark", TNG episode "New Ground", and, DS9 episode "The Sword of Khaless". How do these episodes relate to Star Trek Discovery's fourth episode "The Butcher's Knife Cares Not for the Lamb's Cry". During our second half, we will discuss the William Shatner Documentary "Chaos on the Bridge", the story about the tumultuous early years of Star Trek The Next Generation.
