"Thirteen" focuses largely on Lexa and on Polis. We know that Semet is outraged that Lexa is not calling for war against the Sky People, but how many others feel as Semet does? Either way, we are very worried about Lexa's fate right now.
Lexa: My fight is over. Clarke: No, I won't accept that. Lexa: You were right, Clarke. Life is about more than just surviving. Clarke: In peace may you leave the shore. In love may you find the next. Safe passage on your travels until our final journey on the ground... May we meet again.
