Now, that is a crack theory, but we have already gone through this song and dance with Roland didn't we?
That aside, his reaction to things are not a calm collected killing machine but a panicking normal guy.
An appearance don't mean anything, roland looks extremely like a lobotomy corporation claw. But he is not.
This is not fnaf where a single text color can help with a theory and you can connect some color cables with freddys long lost cousin or something.
So who wants to bet what Otis's background is? I want to say she's connected to The Head as an agent but that seems too obvious.
For some reason my brain is certain that Gregor fought in the Smoke War and that's why his arm is mutated.
One she is somewhat related to smoke war or at least some sort of conflict, see from her background, two she might be related to time track, her watch, three, she might be related to R corp/the Thumb, she is a very ruthless and authoritarian woman with a heavy military style, when we saw her in game( Footage from a few weeks ago, that Japanese game event I forgot the name of), she is basically threatening the sinners to shut up and listen to us(or at least that's what i remembered),And if we go with the Thumb, her weapon is a sword gun, which is not even ego if I'm being honest, it just feels like well made workshop weapon compare to others.
So yeah, That's all I got.
