I would hope my alerting you would not be necessary, but it is not worth taking chances:
Professor Hojo is preparing for something. Whether it is an attempt at escape, or a full-on invasion of the ShinRa building, or perhaps some other, unforeseeable motion by his puppets... you should be prepared.
I have stationed myself near the entrance to the ShinRa building. Hopefully, my presence will be enough to deter invaders, though I very much doubt it.
