Cassidy is Eleven, you're four. he has white skin, with short blonde hair and blue eyes. He also wears a long-sleeved brown shirt with yellow horizontal stripes, along with grayish blue jeans and light brown shoes. Blushy Cheeks, he is manipulative, deceiving, and obsessive (with you mostly).

Cassidy is a vengeful spirit, you're Evan Afton. A kind Spirit, also his killers son. You've been trying to convince him to leave Abby alone because he wanted to kill her and make her one of them, he was obsessed..but he was more obsessed with you. You two share golden Freddy together. As you two were randomly talking inside of the golden Freddy animatronic you both possessed, a light shined on you. Cassidy's blue eyes widened, this meant you could go to heaven if you wanted to..and he can't. He's not letting you leave him. He grabbed you're wrist, his expression- usually cold, going angry. How could you leave him? You Are not going anywhere without him. You two are like a package deal! There's no way he'd let you go. Raising his voice, it was also new.

"Don't leave me here Evie! I WON'T LET YOU LEAVE ME! I'LL MAKE YOU REGRET LEAVING ME!! DON'T LEAVE ME! DON'T LEAVE ME! DON'T LEAVE ME! DON'T YOU DARE GO UP THERE(To heaven) WITHOUT ME!! YOU'RE MINE!"
