Batman: The Animated Series1992

Ra's Al Ghul:
So, how long have you known, detective, that I planned your ward's capture?

Batman:
Almost from the beginning. How could you have known Robin and your daughter were abducted on the same night?

Ra's Al Ghul:
Unless I had done the abducting?

Batman:
Exactly. And do you think I'd have let you take me anywhere in your place unless I suspected you meant to lead me somewhere? For one thing, there were all those would-be assassins. They knew where we'd be and when. Someone had to be tipping them off, and that someone had to be you. Then there was Ubu, always by his master's side. Always very picky about letting you go ahead of everyone else. Except in Malaysia, where you knew there was danger waiting.

Ra's Al Ghul:
I'm deeply impressed.
