[ Iorveth doesn't refute "idiot". He'd thought Astarion to be insincere at best, malicious at worst－ looking for an opportunity to twist Iorveth's arm and make him look, yes, a fool, which was a common turn of phrase back then. A man who would stop at nothing to drag Iorveth down to his level, whatever Iorveth had thought that to be.

So why the fuck did Iorveth enjoy acting a fool with Astarion? Must've been for the same reason that's just been articulated to him. He thinks about it briefly, sifting water over Astarion's bare shoulders with idle care. ]

I certainly didn't know it, either. [ A low hum, almost a chuckle. It's funny now, in hindsight. ] I'd assumed you just wanted to pull the rug out from under me.

[ "I will kill you if you laugh at me", another common sentiment that Iorveth'd infused into every single one of his glares. ] But I'd thought about it, even before you demanded it.
