the virmire survivor goes to alchera after the SR-1 is destroyed. they never tell the alliance. but they sit, quiet, in front of shepard’s helmet, and they think about how easily it could have been them, how many times they’ve escaped death - and their breathing echoes in their ears.
maybe the ghosts of the normandy talk back to them. maybe they don’t.
but shepard finds footprints on alchera, and always wonders whose they were.
no there is no “one true origin” i don’t care how cute your cousland is with alistair
