Delusions of Strength

Illusions Of Force is the fourth chapter in the fourth volume and the seventeenth chapter overall.

Summary
The trainees are now practicing hand to hand combat. Eren and Reiner are sparring together. Reiner charges at Eren with a wooden knife and Eren flips him almost effortlessly. Surprised, Reiner asks how he can do that. Eren replies that he's had practice with a local big kid he used to play with as a kid. Eren also voices his concern about practicing fighting humans. Reiner says that it's better to be prepared.

As they finish their conversation, they both see Leon who is slacking again and avoiding the instructor. The two confront her and Eren ends up trying to practice with the wooden knife on her. As Eren rushes, she sidesteps and trips Eren, who lands face first in the dirt. Going for another round, Annie grabs Eren's arm and disarms the knife. Tossing the knife to Reiner, she tells him it's his turn. Hesitant, Eren reminds him that it's a soldiers responsibility. Reiner charges and Anni takes him down easier than she did Eren. Curious, Eren asks her who taught her to fight, she replies that her father did. Annie agrees with Eren about hand to hand combat, thinking that it serves no purpose. Using other trainees as examples, she tell Eren that their score depends mostly on their aptitude with 3D Maneuver Gear, the rest just about claiming privileges inland. Taking the wooden knife, she runs at Eren and easily gets past his guard. Eren attempts to flip her as he did Reiner, but she reverses it and pins him to the ground with the knife at his throat. She reveals that her father made her learn these moves and the she no longer derives any enjoyment from playing soldier, with that she drops the knife and walks away.

In the cefeteria, Eren overhears Jean bragging about his techniques. Annoyed, Eren asks Jean why he is honing his titan killing skills all in an effort to get far away from them. The argument seems to be dying down until Jean sees Mikasa. After that, he grabs Erens collar, causing the situation to escalate again. Eren uses the technique that he picked up from Annie, which catches both Jean and Annie by surprise. The sound of Jean hitting the ground causes the instructor to come to the cafeteria. Fortunately, they are able to get back in their seats before he sees the reason for the noise. Asking what happened, Mikasas answers that it was just Sasha passing gas. The instructor tell her to show some self-restraint which causes her even more embarrassment. Eren comments that, had they been caught, it could have cost Jean his opportunity to join the Military Police. Jean replies that he fears their score will never be settled. Eren suggests they fight during combat training so it can be passed off as innocent sparring.

The next day, Eren and Annie notice that Jean is working unusually hard all in an effort to overcome Eren. Eren asks about his form when he mimicked her throw. She replies that it was a train wreck, but offers to teach him. Not wanting to be beaten up by her again, he turns her offer down. She offers again, and tells him that he doesn't have to hold back.
