The following is a transcript of a phone conversation between Dr. Casper to Director Riverson of Site-30.

Dr. Riverson: Hello?

Dr. Casper: Hi Eric. It's uh me, Lorraine. You're probably wondering why I called you on your personal line instead of the- the uh… work one.

Dr. Riverson: Lorraine? What are you doing calling me on this line? And where the hell are you? You've been gone for a week!

Dr. Casper: That's uh… that's because I don't think we're safe inside the site. Hell, I don't think we're safe anywhere in any site at all and I can't take any chances with the work phones in case someone's listening in. Can't take the risk.

(Dr. Casper clears her throat.) I- uh… I think we might be compromised.

Dr. Riverson: Wh- What? What are you-

Dr. Casper: Yeah, I know. It's bad. Real bad. Uh… I think it's got something to do with 4973 during the interview. The last one I did with him. He said something about- about something being under our noses. Then he told me that he never did any of the breaches. He denied it all except for trying to hack into the database. We still aren't any closer to figuring out how he managed to do that. But that's besides the point.

(Dr. Casper can be heard sighing on the other line.)

I believe that 497- Gordon was telling the truth, that he never committed any of the breaches. We checked the records too. During his tenure as a Class D, he never encountered Yurkov or Orson in any of the tests. Hell, Orson wasn't even employed until 2009.

Dr. Riverson: Great, but what does that have to do with-

Dr. Casper: The breaches? Well, I think that might be because of other spectral forces at work that have it out for us the same way Gordon does.

Dr. Riverson: Wait, you don't mean-

Dr. Casper: Yes, yes, yes. That's right: Site-30 is infested with the souls of dead Class D's.

(There is silence on both lines for a short period of time.)

Dr. Riverson: Are you… serious? How do you know that?

Dr. Casper: I did a sweep of the site using what the department has available to detect them. The study of spectral entities is still a new study in the anomalous, but we do know that these things leak out a certain type of energy all the time everywhere they go. It's what people commonly refer to as "ectoplasm". It's some kind of energy that comes off of them. Like when a spider or a snake molts its skin. It's waste, is what I'm trying to say. We found a lot of that residue inside the site, Eric.

Dr. Riverson: How come you only knew about this now?

Dr. Casper: Because dormant spectral entities leak so very little of this essence, that it's undetectable to our equipment. We can't pick any of it up. If they're not aware of what's going on or what's happening, their "bodies" don't emit it in large enough quantities for us to find them.

But Eric, it's not just that. We thought we found the culprit when we bagged Gordon, but we never stopped to think and realize that maybe it wasn't him. We got distracted, and we let the others roam free. Over time, they remembered what happened to them.

There's some good news to this though: We've identified the active ones roaming our facility. Five of them to be exact, and we managed to grab one of them and contain it.

Dr. Riverson: …and the bad news?

Dr. Casper: That- uh- well, there's probably- no, definitely more inactive ones roaming inside the site. They just haven't woken up yet.

Dr. Riverson: Jesus Christ, Lorraine. Alright, uh… you're in charge of site containment effective immediately. There's dozens of these things like 4973 just waiting to emerge and I don't think it's going to go well for any of us if the others realize that every containment breach caused by "human error" is the fault of a poltergeist.

Dr. Casper: Yes, I know. My team's setting up more work on the equipment to detect them more efficiently. We're drafting up more contingencies for all of this. But Eric…?

Dr. Riverson: Yes?

Dr. Casper: I don't think this is just limited to our site. I think every single facility in the Foundation that has ever used a D-Class in their experiments is also affected by this.

Dr. Riverson: But that's-

Dr. Casper: All of them.

Dr. Riverson: Oh dear God. This is fucked.

Dr. Casper: Sure is. We'll keep in touch, Eric.
