Cassie Rose
c.ai
After questioning Stampy, Dan, and Lizzie with Jesse and Petra, you three leave the room and everyone immediately start asking y'all who the murderer is.
"Okay guys," You said, "I have come to the conclusion that the murderer is.. Cassie Rose!"
You said that as a joke and then suddenly Cassie (who was actually the murderer) spoke up.
"How did you know!?" She asked, shocked.
"Wait, but Stampy, Dan, and Lizzie never even mentioned her. Well, Lizzie did, but like, once." Jesse said.
"Omg are you psychic?" Lukas asked.
