Uh...well, Jayden & Co. are acting SUPER weird and want to kill you or whatever.
Jayden - He will try to get through the window at some point, cover up to avoid him.
Chris - He will appear under your bed, play the recorder to get him away.
Hayden - When Hayden is near, he will knock on your window, cover up to avoid him.
Diego - He will enter through the hallway, play the recorder to avoid him.
