WARNING: SPOILERS FOR 'THE 100': BITTER HARVEST ARE AHEAD.
At the end of the last episode of The 100, 'Bitter Harvest,' we had quite the big reveal. First though, let's sum up basically what happened in the episode.
The last of the Mountain Men were brought before Commander Lexa and Clarke. Raven also delves into the code of the crashed Ark to try and find something on the request of the ruler of the City of Light. Her name is Ally and Thelonius brought her back to the settlement with him.
At the end of the episode though, we discover that Ally is a computer program who has the ability to dull pain by reworking pain receptors in the brain. She reveals that the reason she wants Raven to let her into the coding of the Ark is because her original creator was working on a second version. She was escaping to space because of something Ally had done, but she was building a second version of the code. However, they find out that there isn't a second version of the artificial intelligence on the Ark.
That's when Jaha drops the bomb: there was a thirteenth station they don't mention at Unity Day celebrations. One they had to blow out of the sky, called Polaris. The end of the episode shows Murphy being tortured for information about the key to the City of Light he was carrying, along with a pod saying Polaris visible. This obviously brings up a lot of questions.
So Many Questions
Why is Titus so eager to torture Murphy for answers when something belonging to Ally shows up? What do the Grounders know about it that they aren't mentioning? Why do they have the pod for Polaris?
We know that when the world ended, there were those who went underground (the Mountain Men). One question has always remained though: if the atmosphere was so toxic, why are there Grounders? I have a theory.
Skaikru are able to survive the atmosphere because of repeated exposure to more radiation in outer space. If someone came down from space after a little while of being up there, they might be able to then survive the atmosphere. Maybe the thirteenth station contained the ancestors of the Grounders. Maybe that's why they seem so fearful of the City of Light symbols. They know what they did, and tales have been passed down from their ancestors.
I know what you're thinking though: they fell from space, how did they survive? Well others were injured when the giant Ark came down from the sky, but the ones coming down from the thirteenth station may have had the keys from Ally that they swallowed. Perhaps their brains were rewired and they were able to survive. Maybe not everyone DID survive, but enough to pass on the tales.
Whatever it is, I'm sure we're all going to be looking forward to seeing what the next episode of The 100 has in store for us. Check out the promo for 'Thirteen' below:
