Black Butler season 5 episode 12 recap

The episode commenced with Ludger and Sascha collecting Hilde's soul. While looking into the documents, Sascha was amazed that Sieglinde Sullivan and Wolfram survived their fated death. At the same time, Sascha was intrigued by England acquiring the inventor of a new type of poisonous gas. The Grim Reapers become impressed by humanity's growth.
Yet, Ludger thought a war was the most likely outcome, given how things had gone. Sascha was thrilled by such a prospect, and thought Sebastian might agree the same. At that moment, William and Grelle arrived. Sascha handed the documents to William and said he could take over. William could sense that something big might happen soon.

Sascha also asked them about the moving corpses, referring to the Undertaker's deeds in the Public School Arc. William said he was still investigating it. After they left, Ludger and Sascha talked about the "Seceders." It was also revealed that those who kill themselves were punished to become the Grim Reapers.
Seceders were those who got tired of their jobs as Grim Reapers. Sascha said she could understand them since she was a human once. However, she liked being a Grim Reaper than a human. Meanwhile, Diedrich escorted Ciel and others to his mansion in Germany. His butler, Heinrich, escorted them inside and had the servants tend to their wounds.
After settling into the mansion, Ciel discovered that Undertaker had met Diedrich few days back. Apparently, the Undertaker lamented Vincent Phantomhive's death. At the same time, he oddly commented that the Earl was still alive. Ciel couldn't understand who he meant.

Meanwhile, Wolfram Gelzer had recovered from his injuries. Sieglinde visited him, along with Ciel and Sebastian. Wolfram apologized to his lady for everything he had done. However, Sieglinde felt she had also betrayed him by trying to leave the village and abandoning him. Hence, she forgave his actions. The next day, Ciel bade goodbye to Diedrich and left Germany for London.
Wolfram and Sieglinde were wowed by London's fresh air and vibrant sight. Meanwhile, the Phantomhive servants headed for the Townhouse first, while Ciel and Sebastian escorted Sieglinde and Wolfram to Nina's tailor shop. The episode ended with Sieglinde dazzling Ciel and others with her new hairstyle and appearance.
