Maybe that mystery person was the missing sister? Just a hunch though (⊙…⊙ )

I got a feeling its the father that escaped

Buuut the mystery guy showed up even before the father escaped. The father escaped after she called the institution. I’m so intrigued thoughhhh ヽ(`Д´)ﾉ

Omg thats true akgcitxutcicy I CANT EVEN RIGHT NOW
(╯°Д °)╯╧╧

Yeaaah i’m freaking out lol. I really can’t wait for the next chapter (๑•ㅂ•)و✧

Their body is also slim unlike the father who's bulky

I'm also thinking. Especially the size and hight match with the missing sister. Also when their father said his daughter is just like him. I think he knew that his daughter is faking and will come to rescue him. Maybe she is psycho. Maybe she killed their dog. Just guessing.

Thats wild, but it makes so much sense

I don’t think she killed their dog but I think that moment was one of the things that made her lose her mind. Even after they were rescued, she’s become like a different person. (╯°Д °)╯╧╧
