Maillol has to think hard about this, and strain bruised portions of his mind. What was Asmodeus's will? He said not to enchant Keltham. Did He really convey exactly that, when He spoke not at all in words? It's hard to blank out all of your own guesses about what Asmodeus could be planning, what Asmodeus could have intended, to ask what Asmodeus meant, when what you need is to hear what Asmodeus told you to do, and the concepts and bounds set around it were neither your own nor mortal at all.
"I'll authorize it," he says. "Make sure you tell Keltham exactly what you're going to do, get his permission for exactly that, do exactly that, no tricks, no games, as if Keltham could read your own thoughts down to the depth of your soul, and don't assume that Contessa Lrilatha already knows that, tell it to her anyways." Maillol is writing down those instructions, even as he speaks, they cannot be entrusted to memory.
