One Room

You are in a room. On the floor is a closed trapdoor that only turns on when you are fully on it. In front of you is a bust of Dev with a loose hat. All around you, there are shelves of books and there is a book about Mentor Trevor right in front of you. What do you do?

Stand on the trapdoor.
Take the hat off of the bust of Dev.
Put the Trevor book next to a book on Jinx
Put the Trevor book next to a book on Sunny.
