Crowley might have protested if he hadn't been so shocked by the suddeness of it. By the boldness of it. Because it was incredibly bold of her to just grab him and essentially lead him down the road. He had been distracted by the wonderful attack on the tire of a passing car when she had grabbed him.
Shame she had to distract him, because he was quite pleased with what she had done. Especially since no one got hurt -which he shouldn't have cared about, except for that whole liking the human race thing.
Trying to ignore the fact that she was touching him, Crowley looked over to her and addressed her question. "You can do whatever you want and not get caught if you want to. But you have to really want to, and you have to use your resources." Like himself. He was a resource. Except that now he couldn't recall if Elle knew he was a demon or not.
Probably not. He didn't exactly broadcast such things.
