After William Afton escaped from hell, Cassidy throwed a tantrum for the escape of William

Cassidy: “I will find you Afton...!!!”

But what cassidy was not expecting it was that William was going to have his payback to her and do the same thing as she did to him in the UCN

Cassidy: wakes up “H-huh..? Where am i...? And why i'm in a office!?”

Cassidy noticed that she entered in her own hell, her own UCN

Cassidy: “GET ME OUT OF HERE!!!!”
