You found me! Congratulations! You don't know me, but lets keep it that way... All you need to know is that there's something far worse out there, and that disk is the only thing keeping it in, and I want it to stay HIDDEN, and SAFE. Here's what I want you to do...
There's an elevator under that old animation studio. Right below Hampton's office. Take it. Take it down to the deepest level it can go. Don't be intimidated by the scale of it all, it's not too difficult to navigate. In Sector 47C, there will be an office space. The cubicle farthest to the upper right-hand corner is the one you're looking for. The disk is somewhere in there. Find it, and leave the place before it crumbles, or worse, before you set something loose.
I know this is a bit of an undertaking, but if there's anyone I'm confident in, it's you. You and Rachel are the only two I've seen who've encountered Alex more than once and Survived. Speaking of, Bessie will be down there too. If you can, avoid her. I'll be seeing you. -Hyde
