I watched the show during it's first season. Then missed most of the 2nd and 3rd seasons. I do know that the Zhaan died and they picked up some new cast members. What I cannot believe when I happened to catch one of the more recent episodes is that Cras(sp?) is now part of the crew and even friendly with Crichton. I just need to know how that happened? I have been getting the dvd's. But, they are only up to the end of season one.
