The 100 returns with some ferocious story lines and even more vicious opponents in the third season. “Wanheda: Part 1” provides a great introduction of what is to come this season (or at least in the next few episodes). “Wanheda: Part 1” is set three months after the terrible disaster at Mount Weather in the season two finale. Things are not so copasetic on the home front. The ark survivors have built their own camp called “Arkadia” and they continue to search for the other drop ship and possible survivors.
