What is the Rot? Why is the Rot?

Spoiler Warning and Holy Wall of Text Batman Warning. I got WAY too into questioning the turbo-cancer here, hopefully my rambling makes sense.

So, the Rot is… weird, from a biological standpoint. Really weird, if you stop to think about it. It’s most frequently described as some variation of cancer, and it certainly fits the criteria for it. Caused by damage to DNA? Check. Multiplies uncontrollably? Check. Comes in both benign and malignant forms, one stationary and the other mobile? Big fat check. Heck, even the Rot cysts eating other creatures kind of fits, according to some research I’ve done – there are apparently cancer cells that will eat other cells, which makes sense in hindsight since cancer cells are cells that have lost important genetic restrictions, which may include whatever lets cells identify other cells as “do not eat.”

(I ain’t a biology whiz and I’m doing research on the fly while getting my thoughts out here, so take whatever I say about biology with a grain of salt)

So, Rot is clearly cancer of some kind, right? Case closed. Except when me and a friend of mine were talking Rain World theories on Discord, she brought up some interesting points that got me thinking.

First point: Rot cells obviously mutate in a way that affects FAR more than just cell replication and termination. Some of the cysts can HEAR. As far as I know, cells in the body do not hear sounds. They communicate via chemical signals and maybe, MAYBE react to temperature. Hearing involves complicated, specialized sensory apparatus to pick up on vibrations in the air. Even if you simplify it and say that it’s only vibrations, that’s STILL a multicellular thing, not a single-cell thing. It’s something that took millions of years to evolve on Earth, if not billions.

And while Rain World’s timeline goes on for long enough that it those kinds of mutations might happen eventually, Rot cysts have the ability to hear pretty much right from the start – because even the Proto-Long-Legs react to your presence like the Daddy Long Legs do, and the Rot in Spearmaster’s campaign, where Pebbles has recently contracted it, reacts the same way as it does in later campaigns. It’s already able to hear.

As far as I know, cancer just means the same cell duplicating over and over again. Are more mutations possible with each division, as errors are made in the DNA during splitting? Probably. But not to THAT extent. There’s no way a lump of cancer somehow mutated the exact complicated genetic blueprint needed to grow organs, at least not without outside interference.

Second point: Cases of Rot are way too consistent across the board. Now, we don’t have a huge sample size to work from, but from what we see from both Pebbles’ Rot, and Hunter Long Legs, they’re… pretty similar. Hunter Long Legs is basically a mobile Rot cyst. They move the same way, seem to grow the same way (starts as a growth inside/on the body before eventually freeing itself from whatever wall/flesh it grew from in some capacity and moving elsewhere), they have the same senses, and they even eat the same way, via something like phagocytosis (how white blood cells “eat” invading organisms via engulfing them and breaking them down in a sac in their main “body.”)

Now, this doesn’t tell us much, because cancer, when it does emerge, is pretty consistent in symptoms/what the mutated cells do once they start replicating. It’s pretty much the same regardless of whatever organism the cancer is happening in. But what ISN’T consistent is what causes the DNA error in the cancer cell in the first place. IRL, cancer can be caused by all kinds of things – smoking, radiation poisoning, being out in the sun too long, drinking deadly chemicals and whatnot, anything that damages DNA. But in RW, the only time we ever hear Rot talked about, or see it present, is in the context of an iterator having f*cked up while mucking around with DNA. Pebbles was trying to create an organism that could change his own genome, and No Significant Harassment created Hunter as a messenger and probably mucked something up in the process in his haste to get them to Moon.

This doesn’t mean that there aren’t other causes of it, of course, we’re working with a sample size of two in an apocalyptic world with who knows how much potentially DNA-damaging stuff around, but… that’s still awfully consistent.

So, combining these points and everything we know to be canon, Rot is:

an organism that lives inside another organism

Until a certain condition is met, it cannot harm said host organism.

Once said condition is met, it goes out of control, wreaking havoc on the organism’s systems and mutating, giving it sensory capabilities and an appetite

Said condition is apparently someone messing up when re-arranging genomes, in yourself or others

It is widespread across multiple different species, at least iterators and slugcats but potentially other species as well.

Once you have a bad case of it, it is apparently NOT CURABLE. Pebbles tried everything he could think of but apparently exhausted all of his options by the time of the Survivor/Monk campaigns.

So, with all the context FINALLY laid out, here’s my wild theory: Rot isn’t a cancer. It’s a symbiote turned parasite. Specifically, I believe it’s a symbiotic microbe that lives inside the cells that make up every other creature in Rain World, and is held in check by a specific gene that all species share, and altering or getting rid of that gene causes it to go berserk, taking over and eventually mutating the host cells.

Yeah, I did watch Parasite Eve let’s plays as a kid, why do you ask? Anyway, hear me out here.

There is precedence for single-celled organisms living inside of other single-celled organisms. They’re referred to as intracellular endosymbiots (hopefully I got the spelling right there), and the most well-known one is probably the mitochondria. The powerhouse of the cell is thought to be descended from some bacteria way, WAY back that was engulfed by a larger cell and not only survived it, but BENEFITED from it. Since then those ancient proto-mitochondria and eukaryotic cells have mutually evolved to be dependent on each other. So it’s entirely possible for something similar to have happened in Rain World.

However, I don’t think it happened NATURALLY, here. Because something that’s able to take over a cell entirely and begin wildly mutating it is NOT something your average cell wants inside of it. There’s a VERY high chance of extinction if you do that. Which means that of course those funky bio-tech loving Ancients either took a look at a wildly dangerous cellular parasite and went “hmmm we can use this” or made one themselves.

Why did they do this? Who knows! Currently, I’m tied between “they needed a better powerhouse for the cell to power the various weird adaptations they’re building into various creatures,” “there was some sort of disease that this parasite gave immunity against and they wanted to make use of it,” and “it gave their creations massively powerful regeneration factors that made them much easier to maintain.” Possibly it was all three. Whatever the reason, the Ancients either found or created this parasite, and put it into their creations’ cells, hoping to reap the benefits.

Well, they got the benefits, but they also got a microbe that hijacked the cells and harnessed their pre-existing DNA blueprints to build organisms disguised as great big blobs of cancer. Which is not exactly ideal, but hey, they just had to figure out a way of keeping the cell hijacking from happening! And the way they ended up going about it was to alter the thing so that so long as there was a specific DNA sequence in the cell, it laid mostly dormant. All the benefits, none of the risks – so long as that specific string of genes remained intact.

And then BECAUSE it was so beneficial, they spread their artificial symbiote and it’s genetic reins throughout ALL of their creations, from the smallest pipe-cleaning slugs to the iterators. Which meant that as their purposed organisms replaced most of the original ecosystem, they spread the symbiote as well. Thus making it possible for pretty much ANY creature on the planet to come down with a bad case of the Rot. And with the iterators, I wouldn’t be surprised if this symbiote is tied to their self-destruction taboos. Try to cross yourself out? Well, it’s gonna maybe happen now, but it’ll be a slow painful death as you’re eaten alive from the inside and all your own parts turn against you, so was it really worth it?

And they never told their creations this perhaps even actively hid it, because why tell them the cause of the main deterrent to them mucking with their taboos? They might find a way around it. The iterators were left ignorant of how Rot works, and because of this they never figured out that Rot HAD a cure after all: rebuilding that genome that reins in the symbiote. Because why in the name of the Void would they repeat the same mistakes that gave them Rot in the first place, and potentially make it worse?

Let's talk a little bit about Mahiru's boyfriend

This post is alternatively titled "Mahiru's Boyfriend Probably Had An Eating Disorder And I Am Very Sad About It So Now You Get To Be Sad About It With Me" but that felt a bit much in the bold title font so I'm trying to tone this down at least a little bit :')

So I was reading this wonderful post earlier (you should too btw it has a LOT of interesting information), and as I was going through the food section something clicked in my brain. Pieces of information that were drifting aimlessly before quickly came together for me and I almost wish they hadn’t because oh boy is it depressing.

Now, nothing I’m about to say here is explicitly stated - but I do think it is strongly insinuated, through the MVs of both ‘This Is How To Be In Love With You’ (TIHTBILWY what an acronym wow) and ‘I Love You’. I am aware that the latter video has a lot of metaphorical imagery, but I still think some of this imagery can be taken in a literal sense to reinforce ideas established in TIHTBILWY.

TW/Trigger Warnings: discussion of eating disorders (anorexia, bulimia, etc.), discussion of suicide and suicidal thoughts. Please take these into consideration and stay safe!

credit to iaobug’s transcribed images from ‘This Is How To Be In Love With You’ used below btw!

Now I’ve always had an inkling this could be possible, but I didn’t realise until recently there was this much evidence supporting a little idea of mine dancing around in my head.

But First, Some Quick Definitions and Criteria

First things first, I think we should briefly clarify what an eating disorder is and what eating disorder I think Mahiru’s boyfriend most likely had.

Here are some definitions:

Eating disorders are behavioral conditions characterized by severe and persistent disturbance in eating behaviors and associated distressing thoughts and emotions. They can be very serious conditions affecting physical, psychological and social function. (source)

An eating disorder is a mental health condition where you use the control of food to cope with feelings and other situations. (source)

And here are some brief introductions to several types of eating disorders:

The most common eating disorders are:

anorexia nervosa – trying to control your weight by not eating enough food, exercising too much, or doing both bulimia – losing control over how much you eat and then taking drastic action to not put on weight binge eating disorder (BED) – eating large portions of food until you feel uncomfortably full

Other specified feeding or eating disorder (OSFED) – A person may have an OSFED if their symptoms do not exactly fit the expected symptoms for any specific eating disorders.

(source)

Okay, so we have some basic information down, cool! This is not fully comprehensive but it will do for the purposes of this segment.

So what eating disorder do I believe Mahiru’s boyfriend had?

I’m not sure! The information we have is not conclusive enough for me to confidently pick an option. What I will say is most likely, and most common, is OSFED and the concept of the eating disorder cycle. People’s symptoms will often overlap with multiple diagnoses, or shift from one mode of behaviour (e.g. the restrictive eating behaviours found in anorexia) to another (e.g. binge eating and following compensatory behaviours found in bulimia).

Things are often not as clear-cut or black and white as we’d like to imagine.

Let’s move onto looking at the MVs, shall we?

This first music video has a wealth of information hidden in its cute magazine-style annotations and imagery - information that, when you look a little closer and consider the bigger picture, raises all the alarm bells in my mind.

Parts of ‘This Is How To Be In Love With You’ That Make Me Pause In Concern, In Chronological Order:

The Bread

Let's start off with a not very obvious one.

One of the first things we learn about Mahiru’s soon-to-be-boyfriend (which by the way this is literally the 2nd time he’s mentioned) is ‘wow he buys a lot of bread’. Insignificant on its own, I know, but consider this through my lens if you will: my man has bought 5 whole baguettes from a bakery. Not 2 or 3, but 5. Actually, on closer inspection there's even more bread of a different type at the bottom of that bag too. These aren’t store-bought, they’re fresh and will probably go stale in a few days. Pray tell, if the man is not eating baguette for breakfast lunch and dinner over the course of 72 hours... why did he buy so much fucking bread?

What comes to mind when I see this is binge eating. Bread is one of the most common binge foods out there; anything with high carbohydrates or high fat content, in fact, often due to its “unhealthy” or “forbidden” nature.

We'll just have a quick look at Mahiru's comment again:

"I thought to buy the same bread he did, but this is far too much for me to eat... ><

I forgot to ask how many calories there are..."

If it hasn't been established by now with the MV's aesthetic, Mahiru cares about her appearance. A lot. Her self-image and beauty directly ties into looking 'good' enough for others, so she can find the love of her life and please him with her looks.

If Mahiru is also calorie counting, this does not bode well for their relationship. I should probably speak in past tense, actually... Mahiru's own self-image behaviours made her blind to her boyfriend's self-image behaviours. There we go.

But I'm getting ahead of myself here.

So, We have an indication of binge eating behaviours. Remind me again what comes after binging?

The Jogging Hobby

Oh, that’s right - purging.

Excessive exercise is an indirect method of purging/compensatory behaviour found in bulimia. A more commonly known purging method is self-induced vomiting, but that's certainly not the only way to counteract excess calories.

So the jogging, while harmless in isolation, is starting to paint an ever-so-slightly worrying picture.

Again, let's take a look at Mahiru's comment:

"I had a chance to chat with him today, and he mentioned his hobby was jogging. ... I haven't exercised this much in ages... I'm totally exhausted..."

The only hobby (not hobbies but hobby, singular) that we learn the boyfriend has is this. Sure, there's one movie that he also likes... but that's it. There's not much else to him! So when the two most prevalent ideas attached to this guy are 'food' (in excess) and 'exercise' (in excess)... you can see where I'm going with this.

And by the way, the post I linked at the very beginning? Well, they worked out the location of where this running loop is, and judging by Mahiru’s position and direction it would suggest she’s already jogged about 5km and beginning another loop. So we’re looking at a jog ranging from 5-10km (or more)...

The Alcohol

Okay, here's a quick pop quiz question for you. Who is more likely to get drunk on the same volume of alcohol: a 5"1 woman, or an average height (5"7 in Japan) man?

In theory, it should be the 5"7 man on the basis of his height and size. Alcohol tolerance goes up the bigger you are.

So why is it that the boyfriend ended up blackout drunk, and Mahiru... didn't?

Let’s take a look at the comment:

“My first date at a bar, how heartpounding!

Here is where I learned he’s the biggest lightweight I’ve ever met! ...or maybe I’m just really good at holding alcohol?

Whatever the case, blackout drunk him is so cute!”

Three possible options:

Mahiru really can 'hold her liquor'. Judging by her sheltered home life and general lack of adult life experience though, I'm gonna press x to doubt here sorry mappi.

The boyfriend drunk more alcohol than Mahiru. Also unlikely, as she calls him a 'lightweight' and I think she would've highlighted this in her comment.

He drank on an empty stomach. Alcohol absorbs way faster if you haven't had anything to eat beforehand. This, I think is the most likely scenario.

Here's a little more on the subject that I found interesting:

You absorb 20 per cent of alcohol into your bloodstream through your stomach and the rest into your bloodstream through your small intestine.

Drinking a small amount of alcohol stimulates your appetite because it increases the flow of stomach juices. A large amount of alcohol dulls your appetite and can cause malnutrition. (source)

What have we learnt so far?

So we’ve established some concerning behaviours here.

He eats in excess

He exercises in excess

He drinks in excess (on an empty stomach)

I’m actually going to move onto material from the ‘I Love You’ MV, but intertwine it with some of the remaining points from TIHTBILWY.

At this point the relationship has progressed, we’re moving into winter which brings with it the holiday season! Yay! Except not yay, because things are starting to look really bad for Mahiru’s boyfriend. We've gone from this:

To this:

The carousel was fine at first but now it’s taking its toll on him. Both of them have tattered clothes but Mahiru looks optimistic, whilst the boyfriend looks very distraught. His cheekbones are visible and overall he looks a lot less healthy. I guess this is a good time to point out how distinct and visible his collarbone has been this entire time by the way? He’s even bonier than before. Not great.

A lot of events occur at this time of year, such as Christmas (celebrated between couples in Japan as more of a lovers holiday) and new years. What happens a lot during that period of time? Food. Lots of it. This point in the year is not ideal for someone suffering from a worsening eating disorder. This is a period of time which someone would want to move very quickly from because they can’t see the end of it.

I think it’s time to read Mahiru’s comment from day 15:

“Happy new years! To celebrate, we went to a shrine.

Predictably, I already have my wish in mind.

May we stay like this until the end of time.

May nobody stand in my way”

She, on the other hand, is very happy for things to remain as they are.

Day 16 - AKA, Oh No Things Have Gone Terribly Wrong

This is where the narrative hits its climax and everything starts to snowball.

Now, we reach this scene where the boyfriend stops walking and breaks down. He kneels on the ground, digs his nails into it, and pleads for... something. Help? An intervention? A stop to this carousel that’s doing him no good and only making his health (physical and mental) worse?

He never speaks. It is a silent plea.

One that Mahiru misses.

Saying I love you but doing what I did, I know I have no right, crossed and covered in sin

My love, it scored an own goal, destroyed my love and me with its weight

Tell me, oh tell me why, can’t I just do it right

What did you do, Mahiru?

I believe that this scene and response:

Is directly parallel to this event:

As in, they’re the same thing.

One more comment to read:

He’ll be in for a big, delicious surprise once he gets home!

I’ve made SO many notes about his favorite foods, and practiced my butt off!

I can’t wait to see the look on his face when he sees it all.

Her love - her surprise buffet to cheer him up - scored an own goal, so to speak.

I don’t think I need to say much about this picture, or this scene. She’s giving him excess but that excess is literally driving him over the edge. The nuance is lost between them, and they both need different things from each other and they’re not getting it. Cake to rats, rats to cake.

They’re back on the carousel, spinning around and around with things never changing, no end in sight.

I want to end on this frame of the MV. You see the pole behind the boyfriend? It’s reminding me of rope, and of a certain visual at the end of the video. The juxtaposition of Mahiru forcing her ‘love’ onto him, and of suicidal ideation being the only way off this ride and his problems.

#milgram #mahiru shiina #analysis #long post #eating disorder tw #anorexia tw #bulimia tw #this is how to be in love with you #ai nan desu yo #I love you #daisuki #I DID THE THING and it's... long. and sad :(#this was a really interesting interpretation to write! it's certainly not bulletproof but I truly believe this guy had problems in life #and mahiru couldn't have changed that fact. did she help? not really! did things get bad bad? y. yeah. but! ...#...I have nothing uplifting to say here. her love was plentiful and well meaning but woefully misguided </3 #I genuinely care about this nameless character now... he looks so happy at the start embracing her and im certain in better--#--days between them they were having a great lovey dovey time!! ugH my heart it hurts.....#if there's typos it's because it's late and I'm tired LMAO
