LJones, there are two different reset buttons that people talk about here, and you're supposed to instinctually tell the difference without much context.
Literally where they fold time back altering reality is the first, or the other is figuratively where some aspect or widget is said, did, demonstrated, learned or expressed by a writer or producer in the script, and then next week it's as if whatever happened last week didn't happen, because the producers don't care and the actual writers don't know each other and have no idea what's happening next week or what happened last week when they wrote their week secluded in a bubble, unless they also happen to be a producer who is taking notice.
Examples...
Tom loves boats in 30 days. The ocean is the best thing ever to Tom, but he never mentioned the water ever again for the next three years.
Neelix needs nano probe injections for the rest of his life after he dies in mortal coil. Never mentioned again.
The cloaked Cardassian ship present during Caretaker, never mentioned again.
Janeway's lizard babies. Never mentioned again.
Naomi died and replaced with a clone, never mentioned again.
Prime Factors, Tuvok and the entire crew betray Janeway, break the prime directive, and a year later, Tuvok gets a promotion.
5 Equinox crewmen join the ships crew. Never mentioned again.
In Persistence of Vision (or Bliss?) Chakotay tells B'Elanna that he has always loved her, and then they make out in a dream. Never mentioned again.
In Alliances Janeway makes Alliances, and then shits on those alliances, and blames everyone else, and then acts like she didn't almost make friends with anyone, and that the universe is still against her for the next 6 years.
In The Chute Harry tried to kill Tom. Sure he forgave him in the episode, but there had to be some pee in Harry's coffee for the rest of his life, right? Never mentioned again.
In Remember B'Elanna is given the life experiences of another person, and a genocide. Never mentioned again.
Neelix deals drugs in Fair Trade. Never mentioned again.
Tom and Vorrik got married polygamously with B'Elanna in Blood fever. Never mentioned again.
This is both figurative and literal. Kes knows the Krenims temporal torpedo frequencies. Never mentioned again, until Seven figures it out herself after Anorax has altered the timeline hundreds of times.
Chakotay was given another persons memories and racism in Nemesis. Never mentioned again.
The Doctor and Seven had a baby in One. The baby fell in love romantically with Seven. Never mentioned again.
B'Elanna goes through a cutting phase in Extreme Risk... Although that connects with her flatlining fetish in Barge of the Dead and the attempt to mutilate her baby later on in Lineage maybe? Although after those three "moments" of mental instability, no one thinks to fix her brain or demote the woman? That's some bad captaining.
Dragons teeth. The Vadwaar were painted as a recurring baddie... They were mentioned once more a year later but never seen.
Memorial, the entire crew were given extra memories that were never mentioned again.
400 klingons were living on Voyager for weeks to months in Prophecy. The following week in Void no one mentioned that it had ever happened, or the omnipresent lilac musk.
Workforce, the entire crew were given new memories... It's possible that everytime they were all given new false memories that the new memories crumbled and faded instantly like in The Killing Game, but in an Episode like Remember, B'Elanna had her old memories side by side with these implants forever. Also in Killing Game and Workforce, it is a miracle that no one got preggers despite spending a month or longer as other people who were possibly less responsible about who they were boning and what precautions they were using while boning the wrong people.
...
The major trauma on the viewer from the figurative reset button used by the producers is all the guest stars who are part of the crew since Caretaker, who are only ever seen in one episode. 170 episodes, and only a handfull of actors were in more than three episodes of Voyager despite being claimed briefly as bestest friends or romantic interests.
"Sigh"
