Marinler

Marinler is the het ship between Brad Boimler and Beckett Mariner from the Star Trek: Lower Decks fandom.

Season 1
SECOND CONTACT

Mariner while inebriated and thus not inhibited is being very friendly if not teasing to Boimler about his recording of captain's log, for his part Boimler seemed to have kept quiet about Mariner wounding him with a contraband blade while drunk, even if during the episode Boimler does accept captain Freeman's mission to spy on Mariner for any offenses his ultimate choice to not report anything to the captain, based on Mariner taking his side even when furious with him, laid the foundations for their much more intimate and close relationship they will enjoy during the series.

CUPID'S ERRANT ARROW

Mariner is paranoid about Boimler's new girlfriend, while the text of the episode motivates her erratic behavior as being related to past trauma with a friend of hers, this particular episode is rife with themes of jealousy and romance, Barbara Brinson the new girlfriend in question was deliberately paralleled with Mariner at the climax of the episode with Barbara's paranoia being explicitly romantic, the episode ends with Boimler and Mariner walking off-screen together with Mariner commenting positively on Boimler's worth as a romantic partner.

TERMINAL PROVOCATIONS

Mariner and Boimler go to a concert together wearing matching shirts Brad made for them. Afterwards, she expresses to him that she's happy that they spend time together, and that he's actually not as annoying as she previously thought; Boimler reciprocates that sentiment.

After defeating a corrupted computer core, Boimler reaffirms that he enjoys working with Mariner. She then reveals that she stole the keys to the Captain's Yacht; the episode ends with the two running off to hang out.

CRISIS POINT

The episode saw Boimler discover Mariner's secret, that she is captain Freeman's daughter information they both decided not to share with the rest of the crew, nearly immediately afterwards Boimler had a personal interview with the captain, sensing his distress the captain encouraged him to say the first thing on his Mind which Brad revealed was Mariner, fearing her secret was out Freeman interrogated him further with an erratic and stressed Boimler blurting out he found Mariner both “hot” and “nasty” before running away in terror.

NO SMALL PARTS

Coming off of the revelation of the previous episode, Boimler decides to tease Mariner about her secret. He inadvertently ends up revealing it to the whole crew, sparking tension between them, as Mariner decides to compete with him for a promotion, desperate to reclaim her lost anonymity. Their bickering, however, is cut short, as the USS Cerritos is attacked by the Pakleds.

During a skirmish with a Pakled boarding party, Boimler confesses to Mariner that she's his best friend, and that he doesn't want her to leave for another ship. She berates him for getting too personal, but not before smiling to herself at the revelation. The two make their way to the bridge, where Mariner takes command. However, the Pakleds end up overpowering the Cerritos. When all hope seems lost, the USS Titan—commanded by Captain Riker—arrives just in the nick of time, and drives away the Pakled ships. Mariner and Boimler exchange a quick glance, relieved.

Mariner and Boimler are later seen chatting in the bar, the latter maintaining constant eye-contact. Boimler thanks Mariner for mentoring him throughout the season. Annoyed by Boimler's attitude, she asserts that they can hang out without her being his mentor. Boimler counters this by saying that this is what she wanted, to which she replies that her target moves. Boimler then declares that he'll no longer be obsessed with promotion, and that he'll start appreciating what he has on the Cerritos. The two are then interrupted by Captain Riker; he commends Boimler for his bravery, and asks Mariner to buy him a drink. It is revealed that Boimler was offered a promotion to the Titan, which—unbeknownst to Mariner—he accepted.

The episode ends with Mariner in her bunk at night, flooding Boimler with angry voice messages, threatening and screaming at him for leaving and ghosting her.

Season 2
STRANGE ENERGIES

Mariner's first scene in the premier of this season dealt with her feeling abandoned by Boimler, with her specifically choosing to not save a holographic Boimler in a simulation, her lamenting she now spends all of her time with her mother now which doesn't feel the same, the holographic Boimler trying to find excuses for his real life counterpart "maybe you intimidate him" which arguably apply more if they were talking about a romantic relationship than a friendship.

KAYSHON, HIS EYES OPEN

In Episode 2 of this season "Kayshon, His Eyes Open", Jet who is sent in to replace Boimler is constantly compared to Boimler by Mariner, despite the eventual understanding Jet and Mariner come to and the sexual tension between the two, Jet recognizes that Mariner would rather have Boimler in his place once Brad is back on the ship and gracefully bows out. Boimler's part of the episode arguably sees him lose his dream job on the Titan with an interesting lack of bemoaning on his part with the most probable explanation that he at least is back with his friends especially Mariner since the whole scene of his return focuses strictly on him and Mariner.

AN EMBARRASSMENT OF DOOPLERS

Episode 5 contains the strongest hints towards Marinler, perhaps paralleling the episode 5 from the previous episode, besides the two of them being assumed to be a couple again Mariner's plan to sneak into the after party is literally just to be Boimler's date (Boimler getting in through pretending to be his clone who serves on the Titan) the emotional high point of their plot this episode is when Boimler chooses to spend his night with Mariner and apologize for his departure to the Titan instead of attending the party where he hoped to advance his career.

THE SPY HUMUNGOUS

WHERE PLEASANT FOUNTAINS LIE

Episode 7 sees Mariner outright inviting Boimler to eat together once they would have arrived on Earth and in the main plot her working behind the scenes in an good intentioned but overly-controlling manner to make sure Boimler does not get put in more danger than he can handle, this episode which also sees a blatant theme of sexuality (albeit in the Billups plot) features a fight between Boimler and Mariner with the two of them in suggestive poses at time.

Personal Logs
""Personal log, Stardate 58001.2. Had some trouble today with a collector ship but whatever, the big news is Boims the betrayer is back on the Cerritos! You know the real winner here is Jet. Truly, I mean it can take years for me to let someone get close, truly, I was going to make his life a living hell. Now, Jet's free and I can focus my energy on being pissed that Boimler abandoned me to go the Titan! You know what feels like order is restored, everything just feels right. And yeah, I mean maybe I sort of missed the purple jerk, but that's like one percent of one percent of the anger. Okay! Whatever! Shut Up! Leave me alone. Boimler has a lot of work to do to get back on my good side. The best part is, he KNOWS he messed up. figuring out creative ways to get back at him is going to give me life.""
