"I'm waiting, Battler-san~~~~! After all, your answers will either hurt or benefit. Like for example, a wrong response could do this," Erika said, completely ignoring Levi as if she underestimated him. As if she were demonstrating her superiority, a small blade of Red Truth appeared within the barrier and pierced itself into Armin's leg. though, the moment of sheer pain disappeared as the blade was just an illusion, a simulation.
"Oh, don't worry, that was just an illusion. But next time, it will be for real," Erika says while clapping her hands once like an excited child.
"....damn...you" Battler cursed in frustration, but knew there was no other way but to play her game to prevent any innocent deaths. "At least give me a description of your damn scenario," Battler said, hinting his anger towards her.
"Why of course. *This closed room has a door, window, ceiling, floor, four walls, and a chain to keep the door locked. Take in mind that the Decalogue is still in effect.* That's all I'm telling you," Erika only gives that much information, and as she said this, the barrier around Armin began to shift into an actual room in that description. Battler knew that to solve this closed room, he had to figure out a way for Armin to escape the room without breaking the illusion that it was a perfect closed room, which meant that someone could leave and enter the room without the need of using the locked door and the window.
