What triggers her disappearance? You have to have reached that stage of the game where a new parasite stain infects the people on the Quarintine platform. She'll disappear after that, I believe. You have to have 100% buddy rating with her, though, to trigger it.

I don't remember the exact mission that she dissapears in. No it happens way after that. I had already finished the main-story and was just doing side-ops with Quiet and D.D. and suddenly Ocelot said that Quiet had disappeared.
