At the end of the scene with Paul, Daniel says to him, under the grasp of a hand shake, "if I travel all the way up there and I don't find what I'm looking for, I'll take more than my money back. Do you understand?". This is the first threat against a human muttered by Daniel Plainview, and it's also, rather ironic, foreshadowing(seems like everything is, eh?). Daniel is proving in that scene that he will take a human life to achieve what he wants. Nothing can stand in his way, and nothing will phase him.
