Lexa wants the Sky People to join the Coalition and become the 13th clan. Some like the idea, while others are weary. Clarke and Lexa come up with a perfect solution: travel the twelve clans after a meeting in Polis. It'll give them time to relax after going through so much, time to prove once again that the SkaiKru is a good ally, and time for Lexa to be among her people. Will the Sky People successfully join the Coalition? Will Clarke and Lexa ever have peace and quiet?
