Attack On Titan - Season 4 - Episode 12 - Guides [English Subbed]

Summary :- Yelena admits to Dot Pyxis that ten months ago, she secretly met with Eren Jaeger, requesting that he apply pressure on the military to act. She suspected that left to their own devices, the military would debate and put matters off until it was too late. Not even the other Anti-Marleyan Volunteers were aware. Onyankopon tells Hange Zoë that Yelena was the one who organized them, and friends who doubted them tended to die "accidental" deaths.

At headquarters, Dhalis Zachary is killed by a bomb placed by Jaegerists hidden in the military. Around a hundred soldiers openly defect in support of Eren, many of them from the Scout Regiment. Knowing that Eren's followers want to connect him with his brother Zeke, Pyxis tightens security to use Zeke's location as a bargaining chip. Hange believes that Zeke planned for this eventuality, so they want to look into Yelena's placement of Marleyan prisoners in certain lines of work.
