Since tonight is a repeat, I will ask old questions about LOST. Does Charlie have the sickness that Danielle referred to OR is Locke drugging Charlie? Is the mole Libby or Locke? Could Jack and Desmond be real brothers? Did Locke have the same spinal injury as Jack's wife? 
I heard that Jack wakes up in the next episode and he’s about to go into surgery to fix that woman’s spine. From that episode on, Lost will be just one big ER clone, with the cast turning over 100% within 2 seasons.
