So,I recently rewatched the trailer for Security Breach,and when the Glamrock Animatronics (Besides Glamrock Freddy) are shown off,Ballora's Music box Crumbling Dreams plays. I had this thought. 'Why Ballora's Music box in specific?' Then,I realized. Chekhov's Law. It states and I quote: 'Every element in a story must be necessary, and irrelevant elements should be removed. Elements should not appear to make "false promises" by never coming into play.' This must be intentional on Scott's part. If you remember back to Sister Location,you can take a look at the Animatronics Blue Prints in the game. And in Ballora's,it states that she was made to distract parents. This is huge. And this box's lemotif plays when Glamrock Chica, Roxxane Wolf,and Montgomery Gator. And this actually gave me some new insight about the line from the trailer. The line 'You will do as I say! You will bring me what I want! And if you fail me,then you will,BOTH of you,BURN!' Might not be talking to Vanessa and Gregory,it might be talking to Gregory's parents. Maybe whoever this is forced them to leave Gregory behind in the mall. It is most likely Montgomery under the influence of Glitchtrap,or Montgomery by himself,as in one of the teaser images for Security Breach,we see that Montgomery's green room is in horrible condition compared to the rest,most likely a result of his aggressive nature. But then again,this is just me rambling on about something I noticed.
