Okay so this is just a theory.
When I hear sister location I think of a second restaurant. Like if you've heard of Everest and Summit high school. There sisters schools made because I think Summit had way too many students so they had to make a new school. Everest. So that's why I used that knowledge to believe Sister Location means a new Freddy Fazbear location that the owner owns.
Look at her style. It's similar to the toy animatronics. So I believe if it is a spin off and judging by Scotts choice of design I think it's set in 1987 but again just a theory.
Her microphone is just like Freddys and the balloons in the background means she's performing at a restaurant. Because well no one wants a creepy Animatronic in there Anniversary party.
Also as you can see she as a much more blocky face. Her face it cut down from the middle and sides which means her face might open. So maybe. Just maybe this makes me believe the metal exoskeleton might make a apprentice from FNAF 2. I'm not sure they do seem to be different modals but I can't rule that out.
Also if you zoom in on the nose you can see a reflection a springtrap figure which could mean he could make an appearance. Scott had said that he wanted to bring springtrap back but he didn't know how. Maybe he decided to bring him back into this game which means this could be part of the FNAF timeline.
Okay I won't continue but let me know your theory's and yeah. This is just a theory. Not actual facts.
Again just a theory
I don't own FNAF! All rights go to Scott! The creator of FNAF!
Don't judge.
