Black Butler season 5 episode 11 recap

The episode kicked off with Ludger and Sascha looking forward to the events unfolding. Interestingly, Sascha observed that Ciel had sensed their presence. Ludger wondered if it was due to the boy's unique lineage. Sascha, on the other hand, felt it was because of the boy's Faustian Contract with the demon, which made him closer to death.
Meanwhile, Tanaka was engaged in a duel against Grete, who was astounded by the man's ability to move without making a sound. At that moment, Mey-Rin shot through Grete's hat, which prompted her to escape. Mey-Rin then joined Tanaka, who was convinced he wasn't young anymore. In the meantime, Tanaka noticed a flare in the sky and realized Ciel had changed his route.

As such, they followed the signal. Elsewhere, Diedrich and others found the military train. On Diedrich's orders, the Phantomhive servants got the train moving. Finnian arrived at the scene with Sieglinde, with Ciel, Sebastian, Tanaka, and Mey-Rin following him. The party was about to move when Wolfram arrived. The butler aimed his gun at Sieglinde, but he was actually targeting Grete behind her.
Wolfram successfully killed Grete, who wanted to eliminate the Emerald Witch. Moments later, Wolfram got shot by Hilde, who had somehow survived the previous tank accident. Hilde was about to shoot twice, but Sebastian arrived at the scene and killed her. Meanwhile, Sieglinde tearfully reached out to Wolfram, who was seriously injured.

The episode then delved into a flashback, revealing Wolfram Gelzer's past. Wolfram had always moved mechanically as military personnel. He followed orders without knowing the consequences. Moreover, he couldn't perceive any color, but only saw the color gray.
Then one day, he was assigned as Sieglinde's protector (or killer if things had gone haywire). Initially, Wolfram was rather annoyed by the task. However, one day, he saw Sieglinde draw a picture of him, carrying her in his arms. Wolfram found happiness that day and finally saw colors.

He swore to protect the girl from anyone who would try to kill her. Wolfram's reverie was broken by Sieglinde's cry, and he realized he was on the train. Meanwhile, the Phantomive servants performed a surgery on Wolfram to save his life.
Ciel wanted to save Wolfram because Sieglinde needed someone who would protect her in the external world, which had far more sinister monsters than the werewolves. Ciel Phantomhive also stated that he needed Sieglinde to stay alive as his insurance.
Sebastian wondered whether the boy truly needed insurance with him around. The episode ended with Ciel telling Sebastian that he was the one he couldn't trust the most.
What to expect in Black Butler season 5 episode 12? (speculative)

Black Butler season 5 episode 12 will continue the adaptation from chapter 105 and likely show Wolfram Gelzer's status.
The episode may also show the Grim Reapers continue their mission of collecting new souls. Additionally, the episode may show the return of a familiar character, key to the previous arc.
