[Belatedly Aubrey realizes she implied Eren’s mindscape creates games. It doesn’t, exactly, but—well, has she played word association with Armin? When he panicked he made a foggy rooftop; when Eren did, buttons clattered and metal clanged. Endless walls rose around a dance floor. Aubrey herself seems to raise a quiet rot, maybe an icestorm—and a labyrinth of shadow.

[Never mind when Eren himself became an illusion. That certainly wasn’t his doing.... Was it?]

[She frowns, lost in that mental montage for a while. Graciously, the world reflects nothing.] It’s not the only one. [Nearly muttered, that. And yet Aubrey thinks the most dangerous things she’s done here haven’t needed a kick from the world at all.]

[Back to Reiner. Stay grounded.]
