On the JBA Headquarters Part 2 level, go into Emile's room and start hacking the safe by his desk. You will hear Emile talking to someone from the doorway. Hide into the wardrobe. After they have finished talking, whistle at Emile. As you whistle, move closer to his bedroom. Lead him inside then hide under the bed. If done correctly Emile will go to bed and sleep like a ghost. He will make no breathing sounds, will not put the bed cover over him, and has one hand on his heart. Note: This may require a few attempts.
