This show still has to stay on brand!
So how did we get here?
The other person who couldn’t transcend?

Bettina Strauss/The CW
They all decided that the exchange was worth it for Clarke.
In this case, it’s transcendence.
That was the moral of the story.

Bettina Strauss/The CW
We thought that it was the most beautiful way to say found family is important.
They are foregoing whatever transcendence is, they’re giving that up to be together.
Why have all the main characters made that choice except for Clarke’s daughter Madi?

Shane Harvey/The CW
They’re not going to have children, this is the last generation, they can’t have offspring.
That choice was made easier for Madi by the fact that Clarke wasn’t going to be alone.
Was this always your original idea for how to end the show?
I can’t really remember that we ever had the details of an ending.
So however that was going to manifest, that was going to be the takeaway.
But the point was always going to be that.
Did you always know you were going to have them come back for cameos?
It happened organically, for sure.
When we landed on what the rules were, it was about who those special people would be.
So no, there was never anybody that we wanted to come back and didn’t come back.
For me, it was Lexa all the way.
Then it was about getting her to agree to come back.
Everything kind of downhill was affected by that, including the ending.
You want the decisions to always be driven creatively, and certainly when it comes to character deaths.
Sometimes unfortunately though we have to react to situations outside of the writing, outside of the creative.
Now thatThe 100is over, do you have any updates on the potential prequel series?
All I can really say about the prequel is that conversations are ongoing.
But the discussions are far, far above my pay grade at the moment.
The same day you find out is when I’ll find out.
We’re leaving them together, making that choice to stay together and live out their days peacefully.
There’s no one left to fight with.
What are you most proud of, looking back on the entire series?
I’m proud that the show will exist and that people can discover it now in streaming.
