Still can't believe Mark though Lucas was only need for one episode. It's crap.
That being said, I love how adamant Lucas was about Nathan going home. I think part of it was as a means to calm Haley down, to give her some peace, but I think part of it had to do with the fact that he knows it's the truth. That he known his brother, knows how strong he is, how much he love his wife and kids, that he would do all he could to get back to them. His faith in Nathan, his want for him to be okay is such a stark difference from his feeling towards his brother at the start of the show. So even though we go no LN or LHN it was nice scene to show how full circle things really are with LHN.
