He became the King of the Ice Nation upon her death.

This comes in the wake of Clarke (Eliza Taylor) learning from A.L.I.E.

The Earth strikes back in season 4.

Its an unbeatable foe.

There are not enough life boats.

The Earth is the ark.

How do we move forward?

In true Clarke fashion, that will be her trying to get everyone on board.

There will be some very different reactions.

Clarke owns her power, Rothenberg noted.

She saved the world last year.

Kane [Cusick] and Abby [Paige Turco] as well recognize that.

They recognize theyre dealing with someone special.

Its her time to do it again.

Thats especially true for Raven (Lindsey Morgan), who was taken over by A.L.I.E.

Its not the same Raven, Morgan said.

She got the A.L.I.E.

upgrade, so shes definitely a Raven 2.0, but its even better than that.

She went through an evolution.

Shes not only stronger [because of the knowledge A.L.I.E.

left behind], but emotionally and spiritually, shes been to hell and back.

For Octavia (Marie Avgeropoulos), Lincolns (Ricky Wittle) death still weighs heavily.

Youre going to see Octavia take a really dark turn, Avgeropoulos said.

Octavia is going to go ahead and do what she does best, which is killing people.

Shell be back for sure.

I love what that character reveals about the world and what that character means for Octavia.

Luna (Nadia Hilker) will be back as well.

She was a breath of fresh air, Rothenberg said.

I loved the total 180 from everyone we met from around the world.

As fans will remember, Luna is a night blood someone who possesses the ability to take the flame.

As of now, theres no new commander, the City of Light is gone, A.L.I.E.

is gone, but the flame still exists, which will play into the new season.

Ultimately the flame is an important thing, Rothenberg said.

We realize the flame is a political artifact as well.

Whoever holds the flame has power.

Though the flame still exists, Lexa (Alycia Debnam-Carey) will not return in season 4.

But it was too dark even for me.
