The fourth season of Star Trek: Lower Decks is getting close to the end with the release of the penultimate episode this week. We have the first images from the episode, but details are so far being held back.
Lower Decks Episode 409
Today Paramount+ released a set of images for episode 409 but they did not release any other details, not even the title of the episode. It appears that there is a concern about anything spoiling the episode. At New York Comic Con last weekend, showrunner Mike McMahan talked about his concerns over leaks for episodes 9 and 10:
“The last couple of episodes for this season are a big swing and I am really proud of them and I cannot wait for you to see them. We held them off [from the press] because I don’t even want a breath of what happens in them to get out. And it just feels like the ultimate Star Trek, the ultimate Lower Decks.”
We don’t have a synopsis for the episode, but in his NYCC TrekMovie interview, McMahan specifically highlighted episode 409 when asked if he has a favorite episode for the series:
“For comedy, I think the first “Crisis Point” might be my favorite. But for heart, I think this upcoming episode 9 is my favorite.”
The one thing we do know is episode 409 arrives on Paramount+ on Thursday, October 26.
Outpost scientists!
A couple things can be gleaned from the images released, including how the episode features the return of T’Lyn. Another thing that can be seen are some Federation Outpost Scientists, like the ones that had a recruitment booth set up in the Lower Decks season 3 episode “Reflections.”

Interesting, though Paramount’s own mobile press website leaked the title over a week ago (it’s since been removed).
OH WOW, yeah, good call spoiler tagging that haha. Very interesting!!
Thanks! BTW, I hope these eps deliver as promised, but man, give me a break on the secrecy hype. I seriously doubt anyone is trying to break the internet to find out in advance.
I really hate spoiler culture, can we just go back to the days of the title and synopsis for every episode was released before the season starts.
Agreed!
Well, it came about because of all the leaks that did far worse. By the late nineties we all could find detailed plot synopses for DS9 and Voyager episodes months before they aired.
I would prefer that to knowing absolutely nothing. But that’s just me.
Looking back, I absolutely regret reading spoilers about Trek movies and episodes before they came out. And I would hate for something I made to not be presented the way it was intended, and spoilers create preconceptions which color how we go into a viewing experience. I wouldn’t want someone to spoil a plot point for me without being asked, so I try to practice some self-control to hold myself to the same standard.
I wouldn’t tell anyone spoilers unless they asked and I like to know ahead of time in case something that negatively triggers me comes up and I end up having a panic attack and miss the rest of everything. I went into The Last Jedi not knowing anything, got negatively triggered within the first thirty minutes and spent the whole rest of the movie disassociating so I don’t remember a thing after that point. If I had known ahead of time I could have been prepared for it.
I dunno. Mike McMahan is recommending fans avoid the internet until after they see the episode.
I wonder if the rumors of the story having to do with the Kobayashi Maru test is true? Still i hope the last episode of this season is at least 40 minutes long as they don’t have much time to finish the story regarding the unknown ship unless they rush it and finish it in 20 or so minutes or the story is continued through out S5 as well.
Where’s Ransom, why isn’t he in the conference room photo
Mariner is not in also.
Yeah but we know she is in the episode.
Why so serious?
Typo: “the return of the T’Lyn.”
T’Lyn is awesome, of course, but I don’t think she needs the definite article.
The T’Lyn is right up there with The Sisko.
CAN’T WAIT!!!! 😃
Hype is good, but it’s also a path to disappointment. We’ll have to see how this week goes.
It will probably be all about why Mariner is the way she is and feature someone who’s a warped reflection of her.
