Re: Should Illia and Decker have survived ?
^I'd actually want to see how the events of "Yesterday's Enterprise" would have played out had the timeline not been erased by Enterprise-C.
What roles would our other heroes (Sisko, Janeway, etc.) have in the dark future? What about Worf and Martok, who clearly would not come to know the Federation as friends or allies?
