The Butler, Going Alone is Chapter 187 of the Kuroshitsuji manga.
Summary[]
As Ada watches the wagon with the blood supplies drive away, she thinks back on last night.
After her conversation with Baldroy, Ada went to the cylindrical outbuilding to check up on the blood supplies. They had not even been able to collect half the amount the Aurora Society had demanded from her. If she cannot meet their demands, her employers will stop funding the Athena Sanatorium and her and her patients' lives will be in jeopardy. Baldroy had told her that he had a plan, but Ada did not know what he meant with that. Then, Baldroy arrived with two pigs he had gotten from a farmer in the neighborhood. He told Ada that he needed her help: She had to fill the bottles with the pigs' blood to make it seem as if they had collected enough blood. This ruse should buy them some time.
Ada protested as transfusing pig blood would be harmful to humans. Baldroy then promised her that he would make sure that the blood never got to their client.
Ada is pulled back to the present when Layla asks her if she is not feeling well as she looks a bit "grim." Ada replies that she is fine and adds that it is time for calisthenics before she goes to fetch her bugle.
Meanwhile, Baldroy is following the wagon with the blood supplies and watches the delivery man meet with two hooded men. The men thank the delivery man for bringing the shipment and then ask if Ada did as ordered this time. The delivery man affirms and shows them the numerous bottles with blood. The men wonder why Ada had a change of heart; after all, she had been whining and complaining before. And although the delivery men is ordered to load the boxes into the carriage, one of the hooded men stops him before he can. He wants to test the blood first.
The hooded man pours a clear liquid in a cup and then drops some blood into it. As soon as the blood touches the liquid, the man realizes that this is not human blood and throws the cup down in anger. The hooded men are furious that this "dwarf star" would bite the hand that feeds her. And as "the gentleman" ordered them to turn her into a "meteor" if she defied them again, one of the hooded men takes out a gun and calls out to the carriage's driver. However, in this moment, Baldroy shoots the driver. This spooks the horses who run off, and the men are left wondering what happened. Before they can do anything though, Baldroy shoots the hooded men in the head and grazes the arm of the delivery man who hurries away.
Baldroy then steps out of the forest and to the corpses. He apologizes to them, saying that he is used to jungle warfare. He did not anticipate that they would figure out the ruse so early; still, it bought them some time. Baldroy is about to return to the sanatorium when Layla stabs him with a knife from behind.
He drops to the ground, and Layla hovers over him, the long bloody knife in her hands. She scolds him for leaving the sanatorium without permission and tells him that he was a "naughty swine" who had to be punished.
