"Maybe."

For now, that was all he could say. Levi suspected there was a good chance, but he'd prefer to be wrong, since it might pose a difficult choice: following such a passage could lead them to a number of important discoveries, or it could send them directly into a nest of titans. In any case, Levi had no intention of lingering. If the area turned out to be overly expansive, then they would need a full squad to investigate it thoroughly.

From dubious experience, Levi was quite good at keeping his bearings underground. Past the cells was a narrower passage that headed roughly southeast, toward the center of the courtyard. Levi lead the way. Initially, the dingy crypt was silent save for their muted footfalls, but then he heard something ahead. Breathing — there was no mistaking it. Levi stopped for a second. The breaths were fast, rattled and heavy. Once he was certain Mikasa heard them, too, he motioned forward with his chin.

They came upon a seated titan. It was stout and pear-shaped, neck crooked severely to one side so that its head could fit with one flabby cheek wedged against the ceiling. The breathing was constant and husky, like an excited dog's. It reached toward them with one bulky arm, but could do nothing else. Despite its overall girth, the titan's legs were grotesquely small, bent inward and seemingly useless. Levi stared at it. Sorry. Repulsive. If only he could gift wrap it to Hange instead of cutting it up.

Actually…

"Leave it," he said. "It isn't going anywhere, and if we come back with more men, it could be a specimen."
