"Ed, you were all going to die anyway. Now you'll have a second chance to live in a future full of wonders you can't even imagine. I'd still like to see where you and I could go." ― Pria Lavesque to Ed Mercer[source]
Pria Lavesque is a Human antique collector from the 29th century who traveled to the year 2419 through a stable wormhole in order to capture the USS Orville and sell it at a high value in her own timeline.
Main article: PriaThe Orville responds to a distress call from a Vega Mining Consortium mining ship Horizon trapped in the gravitational pull of a star. Captain Ed Mercer sends a shuttle to rescue its pilot, Lavesque.
Safe aboard the Orville, Lavesque joins the crew for a drink and flirts with Mercer. Suspicious of Lavesque's motives, Commander Kelly Grayson and Lieutenant Alara Kitan raid her quarters, finding a box hidden under her mattress that cannot be analyzed by the Orville's scanners.
Later, the Orville is rocked by enormous ripples of a dark-matter storm. Lavesque convinces Mercer to let her guide the Orville to safety, which she secretly accomplishes through the aide of advanced, 29th-century technology worn on her wrist. With the Orville's communications array knocked offline, Mercer sets the ship on path towards a Consortium outpost.
Waiting for the ship to arrive at the outpost, Lavesque spends time with Mercer in the holographic simulator and sleeps with him.
The ship arrives at its coordinates, only to discover the destination is a stable wormhole exiting to the 29th century. Meanwhile, engineering discovers in their computer network the obscure box that Grayson and Kitan found in Lavesque's room. Lavesque reveals herself to be a time-travelling antique collector: she commandeered the Orville in order to sell the ship to alien collectors from the future.
Using the device worn on her wrist, Lavesque pilots the Orville through the wormhole and contacts her potential buyers. However, Grayson is able to restrain Lavesque while Helmsman Gordon Malloy guides the ship back through the wormhole.
Her technology is confiscated and Mercer confronts Lavesque directly. Mercer informs her that the wormhole will be destroyed and Lavesque will be eliminated from existence by a permanently-altered timeline. Lavesque refuses to apologize and says Mercer "will always be that messed-up guy who can't get over his ex-wife." Mercer orders Lieutenant Bortus to destroy the wormhole and Lavesque vanishes.
