The cave wants that, too.

Well, the cave can go jump in the frigid waters of the arctic as far as James is concerned, which he's also aware is an utterly ridiculous thing to think, but then again so it the idea that the cave could want anything. But again, Raju has no reason to lie, and James is trusting his experience in this.

But when the rumble comes again at Raju's almost-question, and he rephrases, James is suddenly suspicious. If the rumble is caused by lying, or even lying by omission, then what about Raju's question wouldn't have been entirely truthful itself? Is it just that, because he knows what causes that reaction, feigning otherwise is the issue, or is it perhaps that he knows James lied about his death because he's already aware of the truth?

So James is silent several seconds, only refraining from pacing himself because Raju is already doing so, before he finally decides to just ask. "Has Francis told you?"

He's not sure how he'll feel about it if he did, but that's problem to figure out later, depending on the answer.
