"Origins?"
According to the Phase II boards, "Origins" is no longer the title of the Cadet Kirk and George Kirk story, but will be entitled "The Protracted Man."
The PII episode is based on that David Gerrold story, of the same title, that wasn't filmed for the original series.
Okaaaay...
...but having read the above synopsis, I'm having a hard time seeing how these two stories mesh... A & B plotlines, one (plot B, obviously) as a flashback? Seems messy and convoluted...with all respect, of course. It'll be interesting to see how it's done...gonna be tricky, that's for sure!
