anna12600 asked: Hi, I was just wondering about the other nations from the ark- are we going to see them, have they survived,etc. ?

Are you referring to the other stations of the Ark?

Because all of the nations unified into the Ark many years ago – and cross-polinated. So, the Ark was comprised of 12 different stations (from different countries), but once they had joined, the population merged together. #LongLiveUnityDay

If you are asking what happened to the other stations…

Camp Jaha is “Alpha Station” and the smoldering wreckage discovered in Ep 204 was what was left of “Factory Station” and “Mecha Station” crashed into the water (as seen in Ep 113)…

Some of the other stations (names never revealed) exploded during the risky and violent earthfall.

Did any other stations survive?

Well, that sounds awfully like a spoiler.
