The gears in the trailer are actually making me kinda nervous cause? We saw the missing record in the music department, we ended the chapter next to a ton of dolls, and now gears? What's next, a room full of poisonous ink? Meeting Joey or finding a sequel to his book??? ?????
It’s unlikely there’ll be a sequel to The Illusion of Living, considering it’s kind of an expy of The Illusion of Life or The Animator’s Survival Kit, very real textbooks rather than novels. As for the room of ink, though, I figure we’ve already seen that. Bendy himself chased us away from it. :P
I do think that we’re being led through departments linked to the six representative images, though – in chapter 2, there were various framed images of the same music note that called for the record, and like you pointed out, there was a missing record on the Music Department board. In addition, at the end of the chapter, we seem to have entered the merchandising department, as signalled by the plush toys and the framed image of the plush Bendy. I figure we’ll be seeing the intended subject represented by the gear, too – probably whichever department was in charge of keeping things running in the studio (and perhaps in the Ink Machine itself).
What’s curious to me is that we’ve only actually seen one animator’s office, and that’s Henry’s… and it could hardly be called an office, tucked away in a hallway right next to a staircase. We might assume the various locked doors in Chapter 1 were the other animators’ offices, but that makes Henry’s office stand out all the more due to its positioning.
I’m concerned about Susie and Alice. Part of me suspects that as soon as we get an answer for what happened to her (or both of them), we’ll have our leading theory for what on Earth these toons are, on top of the humans-turned-ink-monsters one we already have. Maybe it’ll support that theory. Maybe it’ll blast it out of the water. (My money’s on the former, but I’m hoping for the latter.)
