Batman: Viral antitoxins... for a plague that doesn't exist. But if the virus is carried through, say, stray dogs and cats, the plague will blanket Gotham within weeks!
Roland Dagget: Days, actually. You know how many strays there are in Gotham, Batman? Three-hundred-thousand. Imagine if even only a tenth of them carried the virus. Not only will this little bottle make me a hero, it'll make me a fortune as well.

Alfred Pennyworth: But I thought you'd grown quite fond of her. And I'd assumed the feeling was mutual...
Bruce Wayne: It's not that simple, Alfred. She's in love with Batman.
Alfred Pennyworth: Oh, dear. These modern relationships are entirely too complicated for me.
