Batman nodded once, confirming what Gordon said. "I've encountered Scarecrow and his Toxin before - that sounds like what you came up against," he told Canary. "Although he seems to be playing with different variations of it lately, several of them lethal."
He was curious about Crane's interest in Nigma, but Gordon was right - Crane was head of the Asylum. It wasn't all that unusual, just a little specific. Nigma's recent murder may provide the explanation though. Anyway, it wasn't the most important thing right now.
"I'll go over to Arkham and check things out," he said. "See what's happening there, and if I can find out what happened to Crane." He asked Canary, "You're coming with me?"
Looking at Gordon, he asked, "Have you contacted the police in Georgia and had them try to make contact with Crane's family personally?"
