After teasing the event for days, Olivia didn't make it all the way Over Here on Fringe this week.

But the Fox drama is building toward a major episode on December 2, as previewed below. Titled "Entrada," the installment will serve as "an unbelievable ending to the journey home" for Olivia. Don't just take our word for that. Listen to what the official Fox promo has to say.

Also included here: a clip from the installment, which features Olivia beseeching Colonel Broyles to help her escape. Her convincing argument? It's the only way to ensure peace between the two universes.
