Uh, pretty much all of them so far.![]()
Actually not. Only 6 of the 9 episodes have the war at the centre of the story. Episode 3 "Context is For Kings" introduces the Discovery and deals with hat went wrong on the Glenn, Episode 6 "Lethe" revolves about finding Sarek in time and Episode 7 "Magic to Make the Sanest Man Go Mad" is about Mudd trying to get control of the ship. None of those stories are dependent of the war going on in the background.
