With O'Neill, actions speak louder than words. He's bitching because he is well and truly pissed at the situation, but he hasn't turned against Gibbs. And I'm glad I'm not the only one who liked Yu. I know that Michael Shanks quit during season six because he felt trapped in the role of Daniel. I wish they would have let Yu take him as a host during that undercover mission they sent Daniel on. Michael Shanks could have gotten to do something interesting, and Yu would have gotten more screen time.
