Surprise! future missions!
At the end of episode Asteroid 685, after the anti-matter explodes, which should have powered the xray laser, that should have deflected the killer Asteroid, McLaren makes a significant comment. He says something like: "If we succeeded, why are we still here?"
I interpreted this as indicating that Bloom failed, that, either, her engineering was wrong, and the xray laser didn't work, as planned, or squeamishness over taking over the pesky soldiers all at once, and earlier, caused a delay that prevented the mechanism working.
I thought, McLaren thought, the Travelers would all die, if the xray laser rorked, and the future they came from was replaced by a different future.
Would the directorate still exist, in the future, if the asteroid was successfully deflected?
We know there were rogue travelers, who went off mission. Maybe some of them figured out how to send messages to teams which were still loyal, that looked like they were coming from the directorate?
Alternately, maybe criminals in the new future they created, figured out how to send them instructions that looked like they came from the directorate. If so their new missions might be to tell them to rob Fort Knox, and bury the gold somewhere their future masters could dig up?
Or maybe the big mission to deflect Asteroid 685 failed? If so the Directorate is still around. Good thing Bloom had them save Dr Delaney... However Delaney doesn't appear in any of the remaining episodes...
