Batman: The Animated Series, Season 1

March:
[confronting Batman with a tranquilizer rifle] My new serum could be even more powerful than Kirk's!

Batman:
[after disarming March] COULD be? What do you mean?

March:
I needed to test it, but before I had the chance....

Batman:
[clearly surprised] You mean you HAVEN'T' taken it?

March:
Of COURSE NOT! The experimental batch was destroyed. I'll have to....

Batman:
Destroyed? How?

March:
I'd been working through the night. I was just completing the final combination. [remembers incident at his lab as he drops the beaker of mutagen upon Francine's surprise entry] Francine burst in. I was startled. You have to understand I was very tired, I accidentally dropped the beaker. The whole night's work, ruined! Francine never guessed what I was doing, she even helped me clean up the mess. All that....glass! [recalls Francine licking her finger after it is pricked by a small shard of glass] Oh, my Lord, Francine, the mutagen...it's in HER bloodstream now! [breaks down at his folly as Batman loads tranquilizer into a pistol of his and then gives March the formula paperwork]

Batman:
Is THAT what it's going to take? Your daughter's life, before you END this insanity?
