Question: Why exactly does Penguin die? He just falls into his "moat" and comes out bleeding and dying. He wasn't hurt by the bats too much. He made reference to there being a "toxic" lagoon earlier in the movie, so are we to assume the water is polluted by toxic chemicals? And if so, how can the penguins swim in it without being hurt?
Question: When Selina/Catwoman has Schreck cornered, she says that him, the Penguin and Batman killed her leaving her with only six lives left. I understand that Schreck "killed" her by pushing her out a window and that the Penguin "killed" her when she fell through a greenhouse, but how could Batman have killed her? She landed safely in a truck filled with kitty litter after she got knocked off the roof, so that can't count.
