Once again I seem to have spotted a gap in the story. Not to say it disappointed me, I loved the dramatic evil Lionel Luthor (Earth 2) however while rewatching the earlier seasons, particularly seasons three and four in which it is shown that Lionel has a unique, terminal liver disease. It was not cured until Lionel and Clark switched bodies in season four's Transference with the help of the Crystal of Water. In Earth 2 if Lionel found Clark instead of Johnathan and Martha how would he have ended up regarding the liver disease. There are many ways in which he could have beaten it but many that would have put Clark off side and turned him against Lionel earlier.
