I would have guessed "To the ends of the Earth."
B5 used the "key" or "pivotal" episode titles for its seasons.
Signs and Portents
Coming of Shadows
Point of no Return
No Surrender, No Retreat
Wheel of Fire (frankly I always wondered why he picked THIS one for Season 5)
His first unfilmed "arc" script was "To the Ends of the Earth" and could very well serve as giving one a good idea of what the FIRST season was mainly about --- looking for a cure for the plague, while also being an episode that shows you a hint of what the REAL Story is going to be. (Signs and Portents did this for B5).
My money would be on that title for S1 name.
