The Shrine

That was a fairly cold ending. First executing the President of the United States/Mount Weather and then executing all of the survivors. Complete genocide. Lincoln finishing off the President's son was pretty badass though.

I think it's clear that Jaha will be the main villain of season 3, and Murphy will become the major hero... I always liked his character, everyone hated him so much in season 1. I also think that by the end of season 3 Octavia will lead a faction of Grounders, and by the end of season 4 she will be the overall commander. I have no idea what's happening with Clarke, but I would really like to see Kane play a much larger role in season 3 than he did in 2, he was a great character in season 1.

i.e. that whole oh no Finn just slept with Clarke and then his fucking girlfriend drops down thing.. god awful stuff. I don't see Murphy being anything other than a tragic hero that ends up dying, but you can kind of get that sense about just about every character. Also the sea cucumber monster was pretty hilarious.

In the Foundation sequels, in a depressing moment, they return to Earth and find not even one bacterium survived eventual effects of the radiation device activated in Robots and Empire. Speaking of Asimov, he jumped ahead until after the human population had already gone into bunker-life. It would have been interesting to do a Children of Men style story that showed the destruction of human society.

There are four groups:
* The Prison Gang - They were in stasis for a while. It's uncertain what they're going to be, seem like assholes. I was hoping for a group a little bit different than other factions we've seen in the past, but they're essentially another faction of spacers. I'm a little disappointed at the moment.
* Clarke - much like she always is, a little more ruthless. She had to kill a couple of prison gang members who attacked her and Madi. This story is interesting, I wish they went more into survival stuff and building up a home, they basically didn't do anything, it focused not on the "How do we survive" plot but the "What are other people doing."
* Belamy's crew seems like the most interesting - they're doing the whole "people are there! Whew! We're safe. The sort of thing Hitchcock made famous where the audience knows the full extent of the danger that the characters are accidentally walking into.
* Octavia has become Underground Calisto from Xena Warrior Princess. This could be cool. So while the Prison Gang look like assholes that might be redeemable, Octavia's group are clearly much bigger, stronger, and more violent.

And one probable hypothetical group: Spacers rebel grounders living Underground, they're either quiet and collaborating with Ocatvia against their will, or in prison awaiting torture and possible execution.

My prediction of the season's plot:
1. Main Conflict: Who controls the great valley.
2. Main Antagonist: Octavia's faction is the new cataclysmic beast at the end of the tunnel. They're likely focusing on digging their way out of their bunker-layer.
3. Secondary Antagonist: Prison gang will have an evil faction, and a good faction. They'll struggle for dominance in a shaky alliance.
4. Alliances: Belamy and Clarke will reunite and align. Belamy and Clarke will team with whoever is the dominant faction is, and Murphy will go the other way while maintaining a shaky friendship with Clarke/Belamy. One in Belamy's group will join the evil faction out of some kind of irrational fear.
5. Escalation: Clarke and Belamy will not realize Octavia's group are murderous assholes, and try to get them out as a means to defeat the evil Prison Gang faction once they take over. They'll replace lawful evil with savage evil on steroids.
6. Climax: Octavia's group breaks free, totally anihilates most of the Prison Gang (both factions) and capture Clarke and Belamy who she thinks are allies; and this will either lead into the second half of the season if it's paced like season 3, or will lead into season 6 if paced like last season.
