There's a great scene in the HBO Chernobyl series where Valery Legasov is challenged, "Please, tell me how an RBMK reactor core explodes."
Legasov replies, "I'm not prepared to explain it at this time."
In the moment, it pushes back on the "tell me right now", yet it implies that given time, he would have an explanation. Later we learn there's more implied in that answer than just not having it ready at hand.
