Arkham Asylum was far darker than expected.

The experiments the Huntsmen found in here was sickening, and the water supply situation Batman had told Ruby about was currently being investigated.

Ruby watched the whole time the water was being tested, while Yang and Blake sat nearby.

"They get any of this into the mains?" Ruby asked as the officer stood up with the results.

"Yes, they did."

"Notify the water company," Blake said. "There's gotta be a way to isolate it."

The officer shook his head. "No, you don't understand. They put it all in. They must've been at this for weeks. Vale's entire water supply is laced."

"Why haven't we felt the effects?" Yang asked.

"Must be a compound that has to be absorbed through the lungs."

Ruby was confused. Batman had brought them here, and had stopped Crane. But clearly there was something here they were missing.

She hoped they weren't too late . . .
