No Need to Rush the Revelation

In "Domino" from "The Orville," Admiral Perry betrays the Planetary Union by delivering the quantum weapon they developed to destroy the Kaylon into the hands of the Krill-Moclan Alliance. Having done so, he declares that he will return to the Union and turn himself in. Krill Supreme Chancellor Teleya however has other ideas, weary of him revealing the new alliance to the Union. The Moclans point out the Union will soon known anyway, but she destroys his shuttle to stop him from telling, even though she probably could have just had him imprisoned.
