I have yet to see anyone talk about it, so I'll talk about it here lol. I'm rewatching the backrooms (hello everything must go), and I'm noticing that there are wind chimes regularly (and I think almost always, if not always) accompanying Dr. Mary Kline in scenes she's in. This seems relatively harmless, or maybe it's not notable, but I feel like it has major implications given it's been confirmed that the movie is a continuation of the YouTube series.

I think it needs to be addressed that in every single video of the YouTube series, we only hear wind chimes accompanying one person. The mysterious Ivan Beck. Someone notoriously associated with the establishment of the backrooms. Generally speaking, we don't actually have a lot of information about Ivan Beck. He has an eye injury, he had a hand in the initial door to the backrooms opening, he theoretically used to work for the government. There's the belief that he's seeking a way into the backrooms (possibly after finding one of the two tapes that clipped back into reality, either the initial Kane Parsons tape or the unnamed girl's tape), and that it may have the key to curing what may be dementia, given the rooms propensity for "remembering" things.

All that to say, wind chimes are associated with Ivan Beck. This is a generally agreed upon fact. So why are they accompanying Mary Kline of all people?

That, I'm not sure of. There are many theories as to what's up with Mary's mother. A popular one is that Mary grew up in the backrooms, and perhaps that's the reason why she ended up in an institution. Because let's be honest here, ASync has a track record of "disappearing" employees who disappear into the backrooms, who become liabilities. Marvin in particular is The Example. Upon disappearing into the backrooms on an exploratory mission. What is days or weeks for Marvin is two months outside of the rooms, and as a result they fake Marvin's death. So this particular theory isn't unlikely.

Similarly along with this theory, we see Clark descend into madness during his time in the rooms. That's another popular theory, that maybe her mother left the backrooms a little less same, and when she leaves making a fuss over a fantastical neverending liminal space, one where she raised a child, of course she gets committed.

So what are the implications of this particular theory (which for the purpose of this post and for my own personal theories, we're going with the Klines living in the backrooms)? I think it is VERY worth noting in terms of this theory that the backrooms were pitched to the government as a way of conserving space. There were plans drawn out for endless apartments and neighborhoods and stores and whatnot, all built into the backrooms. There are many neighborhoods in the rooms, we see many houses and interior design similar to what would be found in houses.

Though this can be attributed to the room "remembering" these places from people. Kane fell into the backrooms, and the room we see in the girl's found footage is confirmed to be the layout of Kane's home growing up. The hotel front in one of the episode of the YouTube series, though I can't remember which atm, is a hotel irl, which I also can't remember the name of. In the newly released Everything Must Go, we see signs from Cap'n Clark's furniture store (which leads into the beginning of the movie where Naren Warne is separated from his group by Pirate Clark, which puts Clark finding the backrooms BEFORE everything must go and the tape at the start of the movie). However, I think there are greater implications to this, especially considering the theory that Mary was raised in the backrooms. Her mother says something along the lines of "they're everywhere", which could be referring to still lives or the bacteria entities, which I think is the main point people pull this theory from. So I'm going to circle us back around to the living situation and intentions of building society in the rooms.

I think the wind chimes accompany Mary because she was the first experiment to see if life is sustainable in the rooms. Ivan Beck is the driving force behind the rooms, believing the rooms hold the key to stopping his dementia and returning his memory, as mentioned above (or at least this is my personal belief. I'm a big fan of MrHunteru's lore compilation and theories). However, to secure funding they need to attempt to execute their initial proposal. Do I actually believe that's the reason? Realistically, no, but until the movie is released to streaming, I have the memory of a goldfish and also I don't have the mind for semantics of theories like this, so that's what we're going with right now. I'll leave the fine details to the experts. Now there are about a million theories and possibilities as to WHY the wind chimes accompany Mary, but idk, this is the one I'm going with. I do think my theory here may mean something or be a possibility, ESPECIALLY considering in the credits, there are special thanks given to Ivan Beck.

Possibly that upbringing is an experiment by Ivan Beck or Async, though I'd think Ivan Beck would have had a personal hand in it given the wind chimes accompanying Mary. Or maybe the mother is someone who stumbled into a nullzone with her daughter, or while she was pregnant, etc etc, and Async was aware and didn't retrieve them. I think this theory in particular is interesting and maybe viable because at the end of the movie, Mary zones Phil out, and we hear wind chimes as the camera pans to a demolished home, which we're led to believe is where Mary is raised.
