Alright, we've established a fair number of Daniel's persistent character traits. He's manipulative, he's well spoken, he's determined, he's hard working, he's caring, he's resentful, he's very good at deciphering character, and he's, above all, an oil man. What is an "oil man"? Well, that's up for you to decide.
I will be skipping through the movie much faster at this point, focusing only on key character moments and pivot points, along with scenes which contribute to the other parts.
