The Cerritos confronts a rift distorting reality and the crew begins exploring the multiverse.
In the series finale, the Cerritos races to close the rift, which is spreading a Schrodinger possibility field with bizarre effects. Ma'ah and Malor seek asylum aboard while fleeing Relga, the sister of Bargh, whose fleet attacks the ship until Olly drains her shields and the rift destroys her vessel.
Unable to close the rift, Mariner builds a dam that holds back its destructive energy but leaves it permanently open. Starfleet launches a mission to explore the multiverse from Starbase 80, overseen by Freeman and her husband. Ransom is promoted to captain of the Cerritos and names Boimler and Mariner provisional first officers, Ma'ah takes command of Relga's fleet, and Rutherford decides to have his implant removed.
