Everything We Know About The 100 Season 4 So Far
Will Lexa make another guest appearance?
Unfortunately, no. The Flame is still around, which means that her spirit is still with Clarke and the others to some extent, but Lexa herself won't be back this season.
But here's who will return...
But on the positive side, Rothenberg also revealed that after their fates were left up in the air last season, Roan and Indra will both return, with Zack McGowan upgraded to series regular. Luna will also return, with Rothenberg praising the character as a "breath of fresh air" compared to the ruthlessness of the 100.
Not everyone will survive
Rothenberg describes this season as "The Earth strikes back," because the imminent irradiation of the Earth, which Clarke discovered in the season finale, will be the "big bad" of this season. Rothenberg called the Earth an "unbeatable foe," and that the conflict of the season "becomes not trying to stop it, because it's not stoppable, it becomes how do we survive? There are not enough life boats. The Earth is the ark." He said that not everyone can survive, so the characters will have to decide who will survive, and whether they deserve to survive after everything they've done.
Water will reportedly be a problem for the 100, as the radiation starts to spread, as well as electrical storms. The SDCC sizzle reel included footage of a huge electrical storm that Jason Rothenberg said "wouldn't happen until the end of the season."
Clarke struggles with leadership--again
According to Eliza Taylor, Clarke will struggle with whether to tell everyone that the world is going to end in six months, but presumably she will eventually, since the theme of the season is reportedly deciding who lives and who dies. Raven, according to Lindsay Morgan, "wants everyone to know because she believes in sort of crowdsourcing the answer."
Octavia will take a "dark turn"
Marie Avgeropolous said that after Lincoln's death and killing Pike, Octavia will be in a very dark place.
Raven has an A.L.I.E. "upgrade"
Raven has always been a bad-ass character, but apparently after she forced A.L.I.E. out of her mind, she adopted some of the A.I.'s characteristics, which left her smarter and stronger than ever.
"She's been through so much. Raven's just evolved. She's in a whole other place now. Raven's done it all. She's like, 'I've been to hell and back and frankly it was kind of boring. What else do you got?'"
Bellamy has not been redeemed
After Bellamy's abhorrent actions last season, I was afraid that all would be forgotten once he admitted he was wrong in the finale. But luckily, we can trust The 100 to remember what this character has done, as Jason Rothenberg said "not to expect Bellamy's redemption anytime soon."
And in the context of the imminent apocalypse, Bellamy might not be a top candidate to get on one of those lifeboats. According to Rothenberg, "Bellamy doesn't think he deserves to make it through all of this," and many of the other characters might agree at this point.
Bellarke won't happen anytime soon
In the same vein, Clarke isn't going to get over Lexa and jump into Bellamy's arms right away. According to Rothenberg, she will move on eventually, but it will take a long time to heal.
"And I can say, as the voice of Lexa - the person who created that character - that Lexa would want her to. Lexa would want Clarke to be happy again. As I think we all would want the people who we love to be able to - not forget us - but to move on and find happiness."
And since Clarke is bisexual, she could easily end up dating a man next, although Rothenberg won't name any names (at this point, I'm pulling for Roan).
Everything is in disarray
Technically, there is neither a chancellor nor a Commander at the beginning of season four, so all the leadership positions will be up for grabs.
Presumably, either Abby or Kane will take over as Chancellor again, but you never know. And as for the Commander, the Flame is still around, waiting to be implanted into a Nightblood. There will reportedly be a search for more Nightbloods at the beginning of the season, and we'll meet at least one (or will it just be Luna?).
