Rachel Dawes compares him to a snake: cunning, slippery and venomous. She holds him responsible for poisoning Gotham but people polluted the city themselves. He is not responsible for creating a market for drugs and contraband - yet she faults him for taking advantage same as any other? One might believe he is a scapegoat for her anger towards another person or problem.

Here is a similiar feeling. Words oozing familiarity, dripping with dislike after only one conversation. But he remains disinterested. Rachel's comparison was a poor one. He prefers the mongoose. Independent, resourceful and most importantly able to adapt.

"Well, can you blame me? You need to stop sending mixed signals."
