The ravens Miss Treason keeps bring Odin to mind.

For him, the two birds were called Huginn (thought) and Muninn (memory) and he’d let them leave him every day so they could fly all over the world before reporting back to him with everything they saw and heard.

Good catch there.

I do so love it when Sybil gets to contribute useful and/or cool stuff

The Pink Pussycat Club has been mentioned in several previous books, so it’s not new. They even, canonically, have at least one male performer - a Mr Harris - on the books.

A ruby that hasn’t been cut and polished just looks like rough red stone. Ruby the troll may well be made of ruby.

Same for Jade. Grey on the outside, vivid green inside.

Mr Shine sticks out because he seems to be made of cut, polished gemstone quality diamonds. That’s new.

Sam loves his family. Now, we see how much.

There’s a polite way to get that information, and a rude way to get the information. Mr Shine is rarely spoken of, and when he is it’s done in particular ways. You’re right when you say Vimes needs the information, but that statement is still true.

A troll would know the polite way. Vimes doesn’t get the distinction, and barges through into the rude way because he doesn’t know. He’s seen the way trolls communicate with each other sometimes (which is a lot of blunt questions, and often letting anger out to play for physical emphasis) and missed the part where this isn’t one of those times.

They’d have to.

Troll genitalia may not correspond exactly to human genitalia (we have no idea what a baby troll looks like...are they born like human babies are born, or do they hatch from geodes like eggs, or what?) but trolls are having children somehow, and there’s nothing to suggest it doesn’t involve sex at some point. They’re certainly not doing what golems are doing and constructing themselves from scratch - trolls are born, not built.

I don’t think the issue that Detritus (rightly) raises with Vimes has its roots in Vimes dealing with more dwarfs than trolls. As far as I can tell, Vimes’ interactions with the two species seem to be about equally frequent.

Where I think this has gone wrong is that Vimes has observed the way trolls speak and interact with each other (which IS noticeably forthright and even outright violent when seen through human eyes...this has been shown many times, usually by Detritus himself) and made a very simple assumption that the same unspoken rules must also apply to him. Unfortunately, he’s wrong on that. It’s a bit like how seeing two black guys throw That N-Word around casually with each other has very different connotations than it does if a white guy tries to join in?

Normally, Detritus would be willing to let things slide a bit. Probably says something to himself or to Ruby that’s like

“It’s Mister Vimes, and if he don’t always get it then at least he TRYING...”

But Detritus can’t let this one slide and pretend it’s a conversation between two trolls where one of them happens to be a bit thick. Not this time. This is too important, he’s been rubbed too raw by the simmering tensions and he just doesn’t have the emotional space for Humans Not Thinking right now. If this was a conversation between two trolls, even a really thick troll would know not to cross that line and disrespect Mr Shine that way.

Even Brick, with his brains leaking out his ears, knows better than to disrespect Mr Shine that way.

I mentioned it because I’m willing to bet that it (or something very like it) is what members of the Watch are telling themselves.
