Before "The 100" Season 5 even premiered, showrunner Jason Rothenberg was already teasing the huge twist coming before Season 6.

Many fans are still reeling from the Season 4 finale twist, jumping Clarke's (Eliza Taylor) story forward more than six years. But apparently that's nothing?

Here's what Rothenberg told Entertainment Weekly about the Season 5 ending twist, when talking about the entire series end game:

EW: For many of the characters we've come to know since the very beginning, this is their third, or fourth, or fifth chance after surviving multiple apocalypses, evil A.I., and everything in between. With that in mind, have you thought about how you would ultimately want to end the series? How long would you ideally like The 100 to last?

Rothenberg: Well, that's hard to say. [In the five years of writing the show], I did have an end point in mind, and that end point has been reached, and yet we broke a whole new story wide open. When this season comes to an end, it sets up a whole new adventure in a way that surprised me. We do keep reinventing the show every year — every year is a new adventure, a new set of bad guys, a new set of goals for our heroes. So as long as we're blessed enough to make it... I think the twist at the end of this season is bigger than anything we've done in the past, let's put it that way. It could set us up for a long run.

Rothenberg teased something similar to Collider, when answering a question on how closely Season 5 looks to how he imagined it would look, if he got to this point in the series:

"...Every season, as I'm breaking, with the writers, the season that's currently being produced, I'm always thinking about what the next season is, so that we can begin to plant the seeds of what that might be. That way, the ending can take us there. And also, to keep it creatively interesting for me, I like to change it up, radically, every season. But we're beyond the point that I initially envisioned, as an end point, at this moment. That's fine. It's elongated, in terms of where the story's going now.

Wait till you see where it goes, at the end of Season 5. We're talking about a change that will make the last change look like nothing. It's really, really exciting, where it could potentially continue to go, and that's how we keep it interesting for all of us, and the audience, too."

Huh. What could he mean? There are any number of possibilities. Hopefully none of them are Jump the Shark moments.

"The 100" Season 5 airs Tuesdays at 9 p.m. on The CW.
