Batman: The Animated Series1992

Dr. Bartholomew:
It's time we had another chat, Batman. Now, tell me about this supposed gas again.

Batman:
I've already told you. When the gas is put into Gotham's water supply, the entire city will be affected. [Standing up] Why won't you believe me?

Orderly:
Easy.

Dr. Bartholomew:
Well, how could such a complex plan be implemented without attracting attention? I think this plot is just another delusion. And deep down, you believe so too. Otherwise, why come to Arkham? The one place where costumed delusional personalities can receive compassion and help?

Batman:
I didn't come here for help! I came to find the criminal behind all this.

Dr. Bartholomew:
Really, Batman. As if a criminal could run an outside operation from in here. Jack Napier? Harvey Dent? Pamela Isley? Or, as you call them, the Joker, Two-Face and Poison Ivy. We keep them all under constant watch.

Batman:
They're not responsible for this madness. There's only one criminal twisted enough to come up with such a scheme: The Scarecrow.

Dr. Bartholomew:
Professor Crane? What nonsense. I saw him this morning in his cell. He's probably asleep even as we speak.
