That mentioned, Star Trek: Decrease Decks isn’t contradicting this reality in any respect, and once we flashback to Marnier’s time serving on the USS Quito, she and her fellow officers are all sporting the grey-shouldered Starfleet uniforms seen within the Next Generation movies from First Contact onward, and within the final three seasons of Deep Area 9 (seasons 5, 6 and seven, beginning with the season 5 episode “Rapture”; which aired shortly after First Contact’s theatrical launch).
Canonically, which means that Starfleet used the grey-shouldered First Contact uniform from roughly 2373 to at the least 2379. We all know Mariner has been on the Cerritos for a few yr, however that she was serving on the Quito in roughly 2379 when that ship made first contact with Galardonians.
However, how lengthy did Marnier serve on the Quito? Possibly for longer than we expect.
Within the new flashback scene, Mariner is rocking a completely completely different coiffure, and naturally, the grey-shouldered Starfleet uniforms of the 2370s. Relying on how lengthy Mariner has been a perpetual Decrease Decker, this scene might happen virtually wherever from 2373 to 2379. We all know it (most likely) takes place throughout or after 2373 (due to the uniforms) but additionally as a result of Mariner’s buddies are speaking about Information’s brother (Lore) teaming up with the Borg, which occurred within the TNG episode “Descent” within the yr 2370.
Assuming this scene occurs post-2373, comparatively talking, the crew of the Quito gossiping about Information having an evil brother who teamed-up with the Borg is type of outdated information. This scene is made stranger by the truth that they are saying “Did you hear what occurred on the Enterprise?” If everyone seems to be sporting the 2373 uniforms, and gossiping in regards to the Enterprise, the reply to that query ought to be “Sure, I heard it crashed right into a planet. After which, they constructed a brand new one which saved us all from a Borg invasion.”
