On Day 110 of 2200, during the lifeboat launch from the dying ISV Resolute, Ensign Diego Vargas stepped through a hatchway carrying a wounded crewmate. He passed through the edge of a natural Nexus opened by the ship’s failing array. Two Diego Vargas stepped out the other side — both carrying the same crewmate, both with one continuous memory running up to that single step, both as physically real as the deck under them.
The Chief Medical Officer ran this reconciliation to settle, for the record, which man was the original and which the twinned instance. She succeeded. Then she sealed it. What survives the black bars below is everything except the answer.
Subjects
| Marker | Vargas, M. (Mateo) | Vargas, R. (Reyes) | Δ |
|---|---|---|---|
| Genome | █████████████ | █████████████ | NONE — IDENTICAL |
| Biometric baseline | nominal | nominal | None resolved |
| Memory index to hatchway | complete | complete | None |
| Memory after hatchway | divergent | divergent | Increasing |
| Cellular age | identical | identical | None |
By every test the ship could run on the day they emerged, the two subjects were one person measured twice. Neither presented as a copy. Neither presented as the original. The instruments did not break the tie because, to the instruments, there was no tie to break.
Differential Markers (emergent — post-fragmentation only)
The only separations the record found appeared after the junction, and widened with time:
- M. — processing latency 0.2–0.3 s slower under acute stress.
- M. — navigation solutions 0.05–0.10% off the sharper subject. Within every operational margin. Never once mission-relevant.
- M. — head shaved Day 127, at Diego’s funeral. Kept shaved.
- Divergence index: ~5% (2204) → ~30% (2220). Brotherly bond: maintained throughout.
These markers are differences that grew. They are not evidence of origin. The CMO records them here so that no one reading later mistakes a divergence for an answer.
Determination
The reconciliation reached a determination. The determination is stated in a single line.
ORIGINAL INSTANCE: ████████████████████████████████
TWINNED INSTANCE: ████████████████████████████████
— Sealed by order of A. Hassan, CMO. Not for disclosure to either subject. Not for the file. Not for command.
Addendum — Day 65, 2220
Mateo Vargas was killed at the Junction 44-F final stand, hull breach, instant. Six hours later the Chief Medical Officer offered the surviving subject the contents of this seal — the answer to who he had been, and who his brother had been.
He declined. The record preserves his words verbatim, at his request, in place of the determination he would not read:
“I am Reyes. Diego died in 2200. Today I watched Mateo die.”
The seal holds. It will not be opened.
Remember when we were Diego.
