Summary:
Chloe had never thought that her happiness would bring about the end of the world.
-------------------------
Tempair stared at the near-perfect timeline through her burrow, her resolve weakening with every passing second. But she knew what she needed to do. She had tried every other timeline, every other option.
She had even tried talking to a past version of Marinette. Tempair had tried arguing for pulling random powered-up nobodies out of the timestream. With all their power, they could prevent Crimsonoir from fulfilling his wish. They could overwhelm him with sheer numbers, they could win! They could keep their happy ending!
But the alternate Marinette had been stern, just like Tempair’s Marinette would’ve been. And now Tempair was in a white void, with time windows all around her.
In front of the rabbit hero, a window to her happiest timeline. She placed a hand upon the circle, and dragged it left, rewinding the timeline, watching her past become an uncertain future.
