In January (Fringe spoilers alert!), consulting producer Akiva Goldsman said that a lot of the May finale would be set “over there.”

We also know the two-part episode will bring back Leonard Nimoy as William Bell - and now we know someone else that will be featured in the show's alternate universe.

Seth Gabel has landed a vital role on the Fox series, as he'll play a Fringe investigator Over There, sources have told Michael Ausiello.

Gabel’s detective will debut on May 13 (the final episode of the season airs on May 20) and might return on a recurring basis this fall.

“We’re trying to do the last two episodes as a singular event, a little bit more movie-like,” Goldsman said. “It’s really one big story. We’re approaching it like a mini-feature. It’ll have a singular narrative drive.”

Gabel has guest-starred on CSI and will appear on four episodes of United States of Tara this year.
