First let me state, again, I don't care about the who stole from who thing, DS9 and B5 are my two all time favorite shows, s, this is merely a curiosity, because it is an incredible coincidence
Sheridan took his Sunday Drive to Meet Lorien (Aired in November 1998, but, was ready to be aird a year earlier at the end of S4, until TNT saved the show for a S5)
Sisko took a Sunday Dive to hang out with his mother (Aire May 1999)
Did JMS pitch enough about the futur story plans to hint at the ending to his arc? I know his original idea was much different as to the end game for Babylon 5
This is not an attempt to stir up anything, or provide proof of anything, it's just a curiosity, since Sisko ws pretty much set up for his end of Arc with the pilot, and it was pretty similar to the end of Sheridan's arc.
