[Don and Terry arrive at the quarantine scene and discuss the situation with Lieutenant Havercamp]
Don Eppes: All right, well the FBI's focus will be on possible bioterrorism, where it started, a probable point of release.
Lieutenant Lee Havercamp: Yes, we'll need to do a vector analysis.
Terry Lake: To track the links between victims?
Lieutenant Lee Havercamp: Yes, and to predict the spread of the illness. The complexities of the calculations require the use of a high-level mathematician, and I've asked one to come in on this case.
Don Eppes: Actually, we deal with a top math consultant. We can get him on it immediately.
Lieutenant Lee Havercamp: I'd love to have him on board, but this is classified on a National Security level.
Terry Lake: Possible bioterrorism.
Don Eppes: Right.
Terry Lake: It'd take a month at least to get a new person cleared.
Don Eppes: Your guy's already got clearance?
Lieutenant Lee Havercamp: Yes, at the highest level. Here he is now. He's a professor from Cal-Sci.
[Charlie gets out of a car and approaches them]
Charlie Eppes: Don. Terry.
Terry Lake: Charlie.
Charlie Eppes: I didn't know you guys would be working on this.
Don Eppes: So, I don't understand, you just said we need someone with top clearance.
Lieutenant Lee Havercamp: Dr. Epps has clearance.
Don Eppes: He does? You do?
Lieutenant Lee Havercamp: Is there a problem here?
Don Eppes: You just never told me.
Charlie Eppes: I wasn't supposed to.
Don Eppes: Right. No, Charlie is my brother and-and he's the consultant I was just telling you about. I didn't realize...
[the victim's mother is shown being taken away on an enclosed stretcher, which cuts this conversation short, but Don and Charlie exchange looks]
