Okay. Fake chest. He rolls his eyes, looking in the direction of that 'mysterious' laughter. But then it sort of clicks in his mind that illusions are powered by magic, and that no one in their trailer should be capable of that sort of magic at the exact moment. He looks to the chest again, running his hand through it's image just a few times to be sure, but it's really not there. It takes him about two seconds after that to stride to the bathroom looking round for his brother.
