Re: parallels could have had a character from ds9
I think he's looking at it the other way around, DS9 character appearing on TNG. Sisko getting over the loss of wife earlier and getting command of the Enterprise after losing Picard to the Borg and requesting Jadzia to be on the Enterprise as the Chief Science Officer and Data as Chief Operations officer and Second Officer.
Did I happen to mention, did I bother to disclose, this man we're seeking with a mole on his nose, I'm not sure of his clothes or anything else, except he's Chinese. A big clue by itself.
