The cafe clock reads 2:14. Vesna has lived this same hour four times. Across the room, a man stirs cold coffee and smiles at her. His name is Calder, and he comes from a future that erases hers. He was sent back to cut one second out of history. She was sent to do the same to him. They both know it. Neither one moves. Whoever acts first, in the right second, wins. The loser's whole world just stops.

Vesna stops waiting. Under the table she thumbs the small device in her coat, the one that crushes a single second flat. She locks onto Calder's timeline and the air around him starts to ripple. But Calder was watching her eyes. Half a breath later, he triggers his own device.

Both devices fire at the very same instant. The two timelines slam together and cancel out. For one heartbeat there is no future at all, just a white, silent room with two empty chairs. Then a fresh clock appears on the wall, blank and waiting, ready to start a time that belongs to neither of them.
