At this year's Comic-Con, Fringe cast members and producers made it clear that season three would focus on the alternate universe in which Olivia is stuck.

But star John Noble recently made it clear to TV Guide just how heavy this focus would be: every other week will rotate between the worlds, as the actor says: "This is a great experiment - it's like two Fringes."

On the September 23 season premiere, fans can expect answers regarding Olivia's fate in the "wrong" universe, Noble added. He told the magazine:

"You'll see a massive episode set in the alternate universe, with our Olivia escaping from the place they put her in. Anna [Torv] does a really amazing job."

Prepare for more alternate versions of your favorite Fringe characters than ever before.
