They also appear to be in a state of despair, either hunched over and crying or, in one case seen in one of the rooms while travelling the vents, banging their head against the wall in a suicidal manner. They will move their heads to look at Henry when he comes near to them.
The first time Henry encounters them will be in the Archives, in which they are all stuck in some position like statues, gathering in front of the Bendy statue. If Henry returns to the room with the statue after pushing the first book, all of them vanished in the blink of an eye.
The next time Henry sees them, one will walk around the walkway in the balcony above in the lounge, having an emotion mixed between in sorrowful and frightened matter as it laments about being hunted down constantly by someone and hopelessly desiring to go home, before wandering back off-screen.
