Cassidy Andrew Fritz Siblings

Cassidy, Andrew, and Fritz Siblings proposes that three of the Missing Children Incident victims Cassidy, Andrew, and Fritz were siblings.

Side Note: This theory is under AndrewGames.

Evidence[]

A FNaF 1 newspaper states that two of the five MCI victims were lured together. Susie, Gabriel, and Jeremy are all shown or implied to have been lured alone, leaving Cassidy and Fritz as the only pair that fits the description.
Cassidy is associated with Golden Freddy, while Fritz is associated with Foxy.
Foxy.exe is in almost the same pose as Golden Freddy's jump scare in FNaF 1.

Golden Freddy and Foxy share the same spot in the hallway in FNaF 2. The Big bites were done by Fredbear(bite of 83') and most likely ether Withered Foxy or Mangle. (Bite of 87')
Stage01, a minigame linked to Fritz, appears to take place at Fredbear’s Family Diner, further connecting him to Golden Freddy.
In Fredbear & Friends you can see Fredbear and Foxy standing next to each other
Under AndrewTOYSNHK or CassidyTOYSNHK this gives them motive because not only did William kill them but they're siblings too.
This could explain the many instances of foxy and Monty being related.

The parrels and connections may be coincidental rather than intentional.
Andrew may not exist in the Games continuity
Just because Cassidy and fritz were lured together it doesn't necessarily mean their siblings
Andrew is implied to have come from a family that doesn't love him or he was an orphan
Andrew said he hasn't had a friend in a long time it's unknown why if under this theory he would say that if he had both his brother and sister there.
- This could be explained under theories such as UCNDissent it would be because Cassidy is against his pursuit of vengeance.
