Let's play a game: Save the Ancients!

And ya know what? That is where telling them after the congruence in a way that it won't matter if it strands us comes in. Besides, if we leave behind a message in a bottle so to speak for them to find after we've gone back no harm, no foul. How can it strand us if we've already returned and the timeline is still in flux? Is there a chance our message in a bottle may not be found in time? sure, but it's better than being "hurp a derp, nothing we can do" with our fingers in our ears and our thumbs up our butts.
