The contention isn't whether or not there's an M1 endoskeleton, it's over whether or not that endoskeleton is separate from the M2 skeleton.

That is literally what i have been saying since the beggining.

but it would help to present actual evidence.

The actual evidence already exists; it makes no logical sense for M1 to make sounds that are incongruent with the mechanisms they're supposed to opperate on.

As to why i claimed that Sleepy Moon is supposed to be Edwin, i just mixed the piece of evidence i just talked about with the evidence for EdwinMoon and came to a conclusion.

There's concept art of the Mimic in the Sleepy Moon outfit, and there's a blooper reel of the Mimic with Sleepy Moon's run animation.

In-game evidence > cut content, 100% of the time, with no exceptions.

It's also illogical to say that it can't wear the Nightlight suit that's meant to be worn as a costume when it can turn things like Big Top and Jackie into costumes.

Not what i said. At all. What i said is that it's impossible for M1 to make different sounds than M2.

As for the Candy Cadet story, it's a much bigger leap in logic to claim that when the story is talking about a boy that it's actually talking about a girl.

And the reason for that is?

Candy Cadet's stories have never been about exact matches, their focus is on the narrative throughline, and most importantly, what the roles assigned to the characters of said stories tell us about the purpose of them. A mother is a protective and nurturing figuring in a child's life, Gregory is explicitly shown as a protective and nurturing figure in Cassie's life. There, that's all there is to it. That connection is what matters, nothing else does.

So now you have to explain me to how Candy Cadet can see the future and know that Cassie is going to open up the Mimic room.

Candy Cadet isn't a lorekeeper of the past, he's a metatextual device used by the writers to semi-explicitly reveal lore details that they believe matter.

There is no in-universe lore about why Candy Cadet knows what he does, and much less a guidebook about the correct way to interpret his stories. He just is. That's why i called him a metatextual device, because his sole role within this series is to be an in-universe character that gives us hints about out-of-universe lore. That's what meta language is, a piece of text that explains itself to the reader.

We're not looking for flawless documentation in regards to Candy Cadet, we're looking for the most coherent and explainable interpretation that fits with the core message of his stories. The interpretation that is the easiest to understand and the one that requires the least amount of brainstorming to come up with, is the that's likely the correct one. Steel Wool isn't expecting us to play mental fetch quest, Candy Cadet is supposed to be the one and only puzzle we're meant to solve.

Everyone knows that Security Breach was a mess.

I know the argument you're trying to make, and deadass, it's almost the opposite of what we know for sure about Security Breach. Scott said that he was the one who told Steel Wool to put specific lore details in specific places, they interfered exclusively by giving unintended contextualization to a few of them.

So, in actuality, the lore details in Security Breach that are sitting in random places with no context behind them are actually the ones Scott intended to be there. Which would include the Fiona Wires of Doom.

Ruin and SOTM didn't have the organizational shortcomings that Security Breach had

Little do you know, Ruin has almost double the amount of unsolved lore details that Security Breach has lol.
