How we cite our quotes: All quotations are from Batman.
Quote #1
SUGAR BUMPS: You look fine.
JACK: I didn't ask.
Jack Napier is a little full of himself. And by "a little" we mean that he is so full of himself that he's overflowing. There is no room for anyone else in his conceited egosphere. And if you think his vanity is bad now, wait until you get a load of Joker.
Quote #2
LT. ECKHARDT: Giant, menacing, supernatural form. Kind of like a bat.
Batman appears only at night, which makes people unsure of exactly what he looks like. And like with many things unknown, people begin exaggerate his appearance until he's something supernatural in form.
Quote #3
[JOKER goes from almost crying to laughing hysterically after seeing his own face.]
At first, it seems like Jack Napier is upset to be permanently disfigured by the acid bath. Then he seems to enjoy it. Does Joker think he looks better as, well, a joker? Or does he decide he just has to own it, and the rest of his "career" as a homicidal criminal is him making the best of his new face?
