Why is Daniel talking to Armand? Why did he text him? He has no obligation to. Agreeing to see him sometimes is not the same as agreeing to keep him fully in the loop. Why did he tell him about this at all? Louis can make fire, maybe he'd know better. Surely getting over his current sadness-anxiety-anger about Louis would be a thousand, a million times more sensible than exposing this to Armand, even though everything about him as already been exposed to Armand, so it might not really matter.

Demonstrate it, like he's demonstrated all else he can do, to Daniel, on Daniel, chthonic psychic tentacles in his brain sifting every cruel thought and revolting teenage scam, controlling his body, controlling his mind, transforming him, feeding him to repair him like a fucking broken car who needed an oil change, and Daniel is going to say, what, yeah, sure, test this on me, I trust you not to go all the way, I trust you to stop, even without Louis there to demand you let up before it's too late? I trust you, and the ringing in my ears right now has nothing to do with terror?

Sure.
