Scott took inspiration From "THE THING," for the sister location.

If none of you seen "THE THING" ultimate in alien terror, I suggest checking this link out: https://youtu.be/17gCRKvA7dk?t=10m47s The signs are all there. 0-0They're faces open up referencing the heads spitting apart from the movie, and now this new animatronic shows up. Compare it to the teaser's sentence."Theirs a little bit of me in EVERY BODY."This is just a guess at this moment, but I think Enard (hoping that's his name) infected these new animatronics some how, the same way the "thing" infects humans in the movie.This new animatronic looks like the head from that infirmary scene, it has tentacle's that feel unsettling compared to cells tail, and just for the cheery on top, if there infected, they can tear themselves apart and create a abomination so hideous you won't be able to see people the same way again. (or in this case a animatronic ever again). If that's the case for night 5-6.Could explain the reason, why its out of order in there first place.Imagine a THING ANIMATRONIC.
