Doc, Warren and Kuruk decide to take a drug-induced journey for a spiritual experience and travel into the dam on an alternate plane. They want to get into the dam, learn what's happening, and stop the attack. So…it's "medicine" time.
It was hard-fought, but they protected the dam. Kuruk and her group decide to stay. And Doc clearly wishes he was staying, too. (Doc and Kuruk sittin' in a tree… fixing dams and fighting Zs. Or talkers. Or all of the above.) What's next, team?
