It occurs to me that there is a bit of a paradox in this episode that I never realized until now. The encounter between Edith Keeler and the truck occurred three times. The original unaltered timeline, the version where McCoy saves her life, and the final version (the only one we actually witness) in which Kirk stops McCoy from doing so.
In that version, Edith is walking with Kirk and mentions McCoy. He tells her to wait here and goes across the street. She would have been safe crossing with him, she waits long enough for the truck that kills her to approach. She then decides to go to Kirk and is hit.
But in the first two iterations Kirk wasn't there. So her reasons, both for being at that scene and transiting the street are unclear. So I have to ask: Why did Edith Keeler cross the road?
(Feel free to answer seriously or tongue-in-cheek.)
