So this theory is pretty bland and im probably wrong here but I thought id share it because it was bugging me

This regards the FNAF 4 room locations in security breach, the hole with the blob and the elevator/scooper sequence at the end of the Ruin dlc. I think that more than ever the room has a significance, more along the lines of maybe if there is more DLC for security breach it will be taking us to the Sister Location area.

With that being said, in the scooper ending of the game we see the costumes in the room where you basically discover the mimic. It brings me back to the discussion in Sister Location about it being 'Circus Babies Entertainment and RENTAL', keyword being rental. Maybe those costumes were some left behined from the rental program of the space? Maybe if it takes us lower into what could be the Sister Location we could be encountering alot more prototypes like what we can only assume what we saw. Theres so much significance I think in the FNAF 4 imagery in the game (the room, the bed picture, the family table) that can only point us more to Sister Location.

With falling down the elevator in what we can only assume is the main ending, it makes even more sense to point us to Sister Location. Also on a side note if the mimic is somehow Baby (being able to replecate voices and whatnot) it could be another pointing factor. Maybe the mimic was sent down to Sister Location as a prototype that was later tampered with, or maybe burntrap was the mimic and once combined with the blob in the cannon ending of the base game would signify the events to come.

Lastly, and probably the least of my thoughts goes to how the blobs main face is Funtime Freddy.

If this confuses some people or if this doesnt make any sense im sorry lol its just been eating at my head and I thought id share :)
