Discworld Wiki

Sergeant Detritus is a character who appears in the BBC America TV show, The Watch. The character is inspired by the character of the same name in Terry Pratchett's Discworld novels.

Detritus is a large, strong, rocky troll, and a member of the Ankh-Morpork City Watch.



Sergeant Detritus accompanies Captain Sam Vimes when Lord Vetinari summons him to discuss a library book stolen from the Unseen University. His presence annoys Vetinari, as his massive weight cracks the floor. When Vetinari first takes Vimes to task for the actions of Constable Carrot in arresting Urdo van Pew, he claims that there is nobody by that name working with the City Watch. Detritus then reminds him that Carrot is the "new boy" who has just joined the Watch.

Detritus later asks Constable Carrot why he became a cop and Carrot explains that when he was sixteen, his dwarf parents told him that his size wasn't simply down to good nutrition, that he was actually adopted and that somebody had thrown him down a mineshaft. Angered, he became a cop to bring justice to the world and police the kind of people who would throw a baby down a mineshaft. Carrot then asks Detritus why he became a member of the Watch. Detritus refuses to say anything and Corporal Angua explains that he doesn't like to talk about it, though Detritus has a flashback of Vimes shouting at him, asking why he had to go and save him.

When Vimes confronts Carcer Dun and his group of goblins with the help of Lady Sybil Ramkin, Detritus and the other members of the Watch rush to his aid. Detritus shields Vimes and Sybil from the crossbow bolts fired by Carcer and his goblins, and while the others fight them off, Detritus dies at the scene from his wounds.

The Watch keep a brick-sized chunk of Detritus, wrapped around with his Watch badge. Cheery carries it around for a while, seemingly for use in self-defence, but it eventually winds up on a desk in the Watch House.

Saving Vimes again[]

Dun and Wonse later swap Sam Vimes with another version of himself from an alternate universe. The original Sam is now "Prisoner 177", an inmate at the Tanty, a harsh prison run by an alternate version of Lady Sybil Ramkin. When he expresses confusion regarding his status as a prisoner, Carrot, who is one of the wardens in this universe, takes it as talking back and orders him to be thrown to "The Beast." Upon being tossed into a pit, Vimes hears a voice of someone declaring "I'm gonna beat ya, eat ya, and excrete ya!" Vimes recognises the approaching figure as Detritus, greeting him warmly as an old friend come back to life, only for the alternate Detritus to punch him in the face and send him flying back. The alternate Detritus continues to pummel and then grabs him, shouting that he killed his best friend - an imp named Pickety Warp, squashed under Vimes when he fell. Vimes shouts back that he is Detritus' best friend, and explains he's not the Sam Vimes Detritus thinks he is. "How come your arm grew back?" Detritus asks; "You think I lost my arm?" asks Vimes and the alternate Detritus replies that he didn't, but Vimes had thought that he did. "Let's find out who you really are," he declares.

He presses Vimes up against a rock, one of the oldest in Tanty's foundations and one of his ancestors - his great great great grandmother. He communes with the rock, who confirms that Vimes is from another world. He explains that stone speaks to stone, even across splintered worlds. He laughs at Vimes's statement that he's captain of the Watch back in his world, saying that his Grandma is laughing too. He tells Detritus that if he wants to hear something really funny, that he's a sergeant in his world. He laughs at this too, but then learns from his Grandma that in the other world, he's dead. Vimes admits that this is true, that Detritus died protecting him, the second time he had saved his life. He says he was the best friend he ever had and the alternate Detritus tells him he's his best friend now. He tells he knows a way he can save him one more time. He then shows him a way to escape, promising that the two of them will meet again.

In the main universe, the last rock of Detritus vibrates in the Watch House, presumably communing with the other reality's version or his Grandma.
