Stevie wanted to come to the Academy because of the famous 'Truly Devious' murder. She is a detective and is determined to find out the truth behind what happened
Larry and Stevie walk to the place where Hayes was seen last and found out that he is dead. Nobody knows how he died or how long ago. Stevie, being a detective, is committed to find out what happened.
Stevie thinks that she has found out who's killed Hayes and plays a truth or dare game with the possible suspect to back-up her theory. She finds out by what is being shared that she is correct and that Ellie was the killer.
After knowing that Stevie is sure Ellie is the killer, Ellie escapes from the Academy. Nobody can find her, despite hours of searching on foot, in cars, and even in helicopters.
