Re: When exactly did Marla McGivers die?
How can "Space Seed" be retconning anything that wasn't "conned" to begin with? It's my understanding that a retcon only occurs when something that was firmly established is changed, not when something is "changed" that was never specified to begin with.
Otherwise one could argue that everything that occurs in "The Cage" is a retcon because none of it was yet established. I don't think that's how the term was intended to be used.
It seems Wikipedia is supporting my understanding of the term.(citation needed)
It was the best of Trek, it was the worst of Trek...
