So, the first attempt to save the village and take out the Witch’s Cult was met by some mishaps, such as the time-consuming misunderstanding that led to a confrontation with Ram, the killing of villagers before evacuation was complete, Emilia taking the field of battle, putting herself at risk, and oh yeah, Subie getting possessed by Betelgeuse.
But when Julius and Felix killed him, he died and came back just like he always did, without any twists due to his possession. And fortune not only smiles, but beams on him, as he wakes up right in the middle of the planning phase, allowing him to casually introduce the new information he gleaned about body-snatching, the traitor in their midst, and Ram.
His new plan revolves around convincing Emilia to go along with “Crusch’s plan” to evacuate the mansion and village, including Emi-tan herself. She agrees, because she believes the plan put before her, while not entirely or even partially of her own making, is the best plan as far as she can tell.
So she’s put on a wagon with some enthusiastic village kids, and sent off to safety, while Subie and the knights capture the traitor and take the metia he was using to pass information to the cult. It’s important to note Subaru himself wore the recognition-blocking robe Emilia threw at him, so she had no idea he planned all this.
Suffice it to say, thanks to learning the lessons of last week’s ‘dry run’, everything goes off without a hitch, as Subaru once again confronts a Betelgeuse now weakened by a lack of fingers nearby. Subie also allows Juli to cast a spell, Nect, that lets him see with his eyes, allowing him to see the unseen hands and cut through them.
This achieved one of Subie’s secondary objectives: to properly make up with Julius. He is, after all, a crucial part of the plan and why, when the episode ends, it looks like the end is near for the Sin Archbishop, and very good for Subaru, who has once more learned from his past mistakes, put pride aside, planned carefully, and relied on and trusted in others.
This is how he has truly become Emilia’s knight.
