Ed and his crew find themselves in a dangerous situation when they appear to explore a mysterious planet in this week’s Season 1 finale of “The Orville.”

According to the synopsis for Season 1, episode 12 of the Fox series, the Orville crew crash-lands on a planet from another universe while on a mission to investigate the origins of an uncharted star.

In the trailer for the installment, the Orville appears to be heading its way to the uncharted star when a planet suddenly shows up right in front of the ship.

“Oh my god! What is that? a surprised Captain Ed Mercer (Seth MacFarlane) asks.

“That is a planet,” Lieutenant Commander Bortus (Peter Macon) replies.

When Ed asks where the planet came from, Lieutenant Commander John LaMarr (J. Lee) confirms that “it just appeared out of thin air.”

To get answers to their questions surrounding the planet, Ed and John, together with Commander Kelly Grayson (Adrianne Palicki), Lieutenant Gordon Malloy (Scott Grimes), Lieutenant Alara Kitan (Halston Sage), and the Orville’s chief science officer Isaac (Mark Jackson) appear to have hopped into a pod to check out the planet’s biosphere.

Although the promo clip shows the crew having a rough entry into the planet, Ed, Kelly, Gordon and Alara are seen walking on the surface of the planet all in one piece at the end of the video.

Ed and Kelly also reconsider getting back together in the episode. But based on Palicki’s recent interview with Uproxx, it seems that the exes won’t end up rekindling their romance at the end of the season-ender.

“Here’s the thing, it’s the Ross and Rachel,” Palicki said of Ed and Kelly’s relationship. “It’s the Lois and Clark, it’s the thing that will go on for as long as it can, the will-they-won’t-they. And they’ll have maybe moments where they get together, they might have moments when they don’t. It’s that really interesting line that I know Seth is trying to balance in the writing, because you can’t go too far too soon.”

“The Orville” Season 1 finale, titled “Mad Idolatry,” airs on Thursday, Dec. 7 at 9 p.m. EST on Fox.
