This was no real broadcast order, the show was syndicated worldwide and stations ran them in whatever order they chose. For example, in NY, the premiere was followed the next week by "Dragon's Doman," the penultimate episode of the season.
No, I'm going by production order, the order on the video releases. Specifically, I was talking about "War Games," which showed Koenig firing first, followed by "The Last Enemy," where he does the same, but agrees with Bergman who says "shoot first and ask questions afterward, that's not really your style, is it John?" Granted, the "War Games" scenario was an illusion, but apparently what Koenig was very much about to do until he got a glimpse of the possible repercussions of that choice.
Man, I know too much about that show...
