“They want a second chance, and they’re going to fight for it.”
Below, Rothenberg teases the season to come and howThe 100might end.
The trick of that is you have to be consistent while being different, if that makes sense.

Are they dead are they alive, are they stranded?
Let’s talk about Clarke.
What made you want to give Clarke such a maternal arc?

Michael Courtney/The CW
To sacrifice the few to save the many has kind of been her thing from the beginning.
Well, when one of those few is your own child, you’re not going to do that.
And that’s going to be interesting all season long.
That’s a relationship that drives her in a way that nothing else has.
We’re putting them on opposite sides of a struggle.
She’s definitely sort of their queen mother?
She’s in charge and loves her people.
That’s a better way of putting it.
“Queen mother,” not “maternal.”
She feels that they’re the chosen ones, and they’re the ones who deserve the last valley.
They’ve survived hell and they’re not going to come out and settle for anything other thanthatreal estate.
What makesCharmaine (Ivana Milicevic)different from previous villains we’ve met?
I apply that word “villain” loosely to her.
She’s someone who, as a character, I think some people are going to root for.
What are her people like?
They want a second chance, and they’re going to fight for it.
With that in mind, have you thought about how you would ultimately want to end the series?
How long would you ideally likeThe 100to last?
Well, that’s hard to say.
So as long as we’re blessed enough to make it…
It could set us up for a long run.
The 100returns Tuesday, April 24, at 9 p.m.
ET on The CW.
