The other week, I dreamt that one of our number had died. A terrible battle, back in my world, and she'd sacrificed herself so that the rest of us could survive.

She was in the video our Conductor had given for the incentive. That's at least two.

Worlds where everything was the same, but where she might have lived. Or where I may have died.

Only one of the other girls I remember managed to never fall, but... she also remembered every timeline.

But the interloper wasn't her.
