Nobody can get into Overseer Olivette's terminal. The password might be corrupted. I can't make sense of this thing, and I've finally convinced the Overseer to let it go and allow me to set up a new terminal. Olivette probably was hardly even using the thing anymore. I doubt there's anything important on it.
