The Butler, Escorting is Chapter 145 of the Kuroshitsuji manga.
Blavat complains about the rough drive to Scotland Yard while Sebastian and Ciel silently listen. He then asks Ciel how it feels like to have gone from being an earl to a serial killer. Sebastian asks Blavat the same as he was a famous fortuneteller and is now a prisoner; Sebastian also remarks that, despite everything, Blavat does not seem to be bothered by his situation. Blavat claims that it is part of his job, and Sebastian replies that he did not know that a fortuneteller's job was to risk their own freedom by protecting cult leaders and accusing innocent people.
Blavat insists that his prediction has been right though: a star, drawn away from its orbit by a collapsar; a star now lost in the dark. Sebastian mocks him that he only gathered people's information in advance and presented them as "predictions." Blavat admits that while his "divinations" were a ruse, he really knew that Sebastian was "different" the moment he saw him.
Then, a police officer yells at them to be quiet, but Sebastian only tells him a "poem," and right afterward, the police officer and his colleagues are attacked by snakes. A tree falls down on the road right in front of them; the carriage goes astray and loses a wheel before crashing.
Meanwhile, at Phantomhive Manor, Undertaker asks "Ciel" if it has been a good idea to let the servants go. "Ciel" then explains to him that he and his twin never properly fought in the past and that he is ecstatic to finally have this opportunity now. Tanaka serves "Ciel" tea, and "Ciel" wants to know why he did not leave with the other servants. Tanaka only says that he has served the Phantomhives for two generations.
Also heading to Scotland Yard, Fred Abberline ponders about why Ciel went as far as to steal his brother's identity as, in case of his twin's death, he would have inherited everything anyway. He cannot find a plausible answer to his question, can only rule out that Ciel most likely did not do this for the money, before his carriage arrives at the location where the prisoners' carriage crashed.
Fred cannot believe what he is seeing and asks Blavat, who casually sits on the fallen tree, where Ciel and Sebastian are. Blavat tells him that he does not know where they are before he is led to another carriage and Fred sends out a search party for Sebastian and Ciel.
