Saving the relationship drama for next season? Though I wouldn't be surprised if the break-up gets confirmed in a single line. From Jennifer's expression when Mariner's back on the Cerritos, I'd say she knows that she was in the wrong, but she's also the only one who doesn't offer some form of reconciliation. The Lower Decks crew immediately apologizes to Mariner for not supporting her more, Freeman is ready to reinstate her into Starfleet at once, and Jennifer...just hides behind her drink. If she can't get over herself enough to offer an apology, then she's definitely not gf material.
