Who do Craig Thomas and Carter Bays think they are, Shonda Rhimes?

The How I Met Your Mother creators and producers, who kind of dropped the ball with a fifth season that was all over the freaking place, says season six will change ... everything.

“We’ll be, from the first episode on, exploring a new saga for the characters,” Bays told EW. “There’s definitely going to be a big game-changing moment in [that] episode.“

Moreover, they say the new season of How I Met Your Mother will be more like early ones, less like the most recent one, and nothing we’ve seen before. Whatever that means.

So what exactly is the game-changing moment in question? Is guest star Rachel Bilson, who reprises her role as Cindy in the premiere, involved in it somehow?

“We’re taking a little trip forward ... to get a glimpse of a huge, huge day in Ted’s life," Thomas says. "It’s actually going to make it like a whole new story.”

"If HIMYM is a three-act play, this is kind of the beginning of the third act. [In it, there’s] going to be…a huge push that will lead us into the last big chapter.”

“And we’re going to have actual mythology,” Bays adds.

“There’s going to be a Minotaur ... a griffin. It’s crazy.”

Jokes aside, the duo is already planning the inevitable conclusion to their love story told in reverse: “We have an idea of where [the series] will end up,” insists Bays.

“We’re just going to have to ask the audience to trust us.”
