TDK spoilers
Highlight to see.
I was just wondering if I am reading too much into this, but when Lucius and Bruce are talking about the new suit, this exchange (or something similar) takes place:
Fox: "The separation will make it more vulnerable to knives and bullets."
Wayne: "All I care is that it'll hold up to dogs."
Fox: "It should do fine against cats..."
Is that like a less subtle Joker card? A possible hint for the next film? And, yes, I am thinking Catwoman...
