[Inside a military jeep, as Fomin and Bryukhanov prepare to meet Shcherbina...]
Fomin: It's overkill. Pikalov's showing off to make us look bad.
Bryukhanov: It doesn't matter how it looks. Shcherbina is a pure bureaucrat, as stupid as he is pigheaded. We'll tell him the truth in the simplest terms possible. We'll be fine. [Both exit the jeep] Pikalov!
[Pikalov joins in with Fomin and Bryukhanov to welcome Scherbina. Legasov is standing at a distance as Shcherbina, alone, is saluted by Pikalov]
Bryukhanov: Comrade Shcherbina, Chief Engineer Fomin, Colonel General Pikalov, and I are honored at your arrival.
Fomin: Deeply, deeply honored.
Bryukhanov: Naturally, we regret the circumstances of your visit, but as you can see, we are making excellent progress in containing the damage. [Pulls out his notepad] We have begun our own inquiry into the cause of the accident, and I have a list of individuals who we believe are accountable.
[Shcherbina reads through the note and gestures Legasov to join them]
Bryukhanov: Professor Legasov, I understand you've been saying dangerous things.
Fomin: Very dangerous things. Apparently, our reactor core exploded. Please, tell me how an RBMK reactor core explodes.
Legasov: I'm not prepared to explain it at this time.
Fomin: As I presumed, he has no answer.
Bryukhanov: It's disgraceful, really. To spread disinformation at a time like this.
[Legasov, in a tense situation, says nothing and looks to Shcherbina]
Shcherbina: [Notices Legasov and turns to Bryukhanov] Why did I see graphite on the roof? Graphite is only found in the core, where it's used as a—neutron flux moderator. Correct?
Bryukhanov: [beat] Fomin, why did the Deputy Chairman see graphite on the roof?
Fomin: Well, that—that can't be. Comrade Shcherbina, my apologies, but graphite...that's not possible. Perhaps y—you saw burnt concrete.
Shcherbina: Now there you made a mistake, because I may not know much about nuclear reactors, but I know a lot about concrete.
Fomin: Comrade, I—I assure you—
Shcherbina: I understand. [Points to Legasov] You think Legasov is wrong. How shall we prove it?
Vladimir Pikalov: Our high-range dosimeter just arrived. We could cover one of our trucks with lead shielding, mount the dosimeter on the front.
Legasov: Have one of your men get as close to the fire as he can. Give him every bit of protection you have. But understand that even with lead shielding, it may not be enough.
Pikalov: [grimly] Then I'll do it myself.
