and -- a couple of fevers of unknown origin at boston municipal that the infectious disease docs can't figure out. that's all we've got on the log. they've probably got some atypical strain of lyme and the boston doctors have just missed the boat. mister scott -- jimbo. we're trying to figure out how you got this disease. it's important, so try to help me. you work at an animal facility in san jose -- jimbo's eyes are blank. he's dead. i don't know. that's why we'll need a post. go very carefully, very slowly. maximum sharps precautions. sweat drips off boston doctor #3's face, fogging his visor. he starts to make the first cut, but his hand is trembling too much. don't let your eyes leave the blade. ever. and you'll be okay. doctor #3 cuts deep into jimbo's ribs but no matter how slowly he cuts, the sharp edge of the scalpel seems too close to his fingers. pull back to reveal they're doing the autopsy in a plastic tent using negative pressure suction pumps. as the pumps whir. cut to: it's as if they swallowed a bomb and it went off inside them. i don't know if it's motaba but it sure looks like what gillespie described. intercut with: too many. the medical staff didn't know what they were dealing with so they didn't take precautions. they're scared outa their minds. julio gazes through the glassed-in walls at the half- dozen pathology residents and nurses, peering at him with worried expressions. he spins around in his chair so he doesn't have to see them. that's just the beginning. patient zero -- this guy jimbo scott -- worked in an animal quarantine facility in san jose, california. that's probably where he picked it up. probably the whole place is infected by now and is gonna have to be nuked. it gets worse. jimbo here takes a goddamn plane from portland to boston. the plane stopped in chicago. two hundred and eight people on the first leg, and christ, something like two hundred and fifty on the second! if this guy was infectious, by now the whole country's been exposed. and gillispie says there's no treatment for this mother, nothing to do but pronounce people dead. what are we supposed to do, robby? christ, what the hell are we supposed to do? i don't see anything about his coughing. -- that's thousands of people -- -- this whole hospital is buzzin' with rumors. it's gonna hit the press real soon. what are we gonna tell them? gillespie's the only one who can tell us. robby has mixed emotions: the last person she wants to involve is her ex-husband. got it.
