The Ring-Spirit ignores the intended offense. It's a weak attempt at an insult, and he'd much rather focus on the gratification that the pharaoh had agreed with him on a death sentence.

"About time! I killed him and it didn't take." That's unnatural, right? People die when murdered, that's how it works. And ok, so maybe the Ring-Spirit doesn't exactly die when killed either, but that's him. He's supposed to be special and unnatural.

He decides against mentioning that his Item leaving Shadi's 'care' hadn't been fully left up to Shadi. Then it occurs to him they might have been calling his former host the 'unstable narcissist' and he's not sure how he wants to handle that.
