For better or for worse, Hythlodaeus is not actually aware of the extent of thoughts going through his friend's mind, and takes the glare and dismissiveness as the usual sign that he hit close to the mark. He picks out a change of clothes from the wardrobe, sitting down on the bed to pull on his socks first. It's certainly a deliberate ploy to annoy Hades.

"It was good, was it not? You called it passable, which is praise when it's coming from you."

He disappears into the bathroom again to put on the rest of his clothes and brush his hair, and emerges some minutes later, looking quite content about having warm clothes again. Bliss.

"Shall we go? 'Tis not far, just down the road. They do wonderful pastries."
