Both Jacob and Nemesis/Smokey call eachother friends. Nemesis to Jacob in The Incident:"I'm going to find a loophole my friend". Jacob to Hurley in LA X: "I was killed by an old friend who grew tired of my company". Since when do friends kill eachother or go to great lengths to prove the other wrong. You guys think these guys got along at one point in time but had a falling out of epic proportions? Or is it just a figure of speech, like Caesar or John McCain?
