To get this trophy, you pretty much have to let the Origami Killer walk free and have none of the clues tie to him. Play through the game (perferably on your second playthrough) with AUTOSAVE on, starting from Hassan's Shop chapter. You cannot use chapter select at all, so you must play from the designated chapter to the end. Also, you need to make sure the following events occur in the following spots. 1) Hassan's Shop - Don't do anything at all and stay in the back of the store. 2) Fugitive - Just wait when you get to the street, making sure you don't get away. 3) Manfred - Make sure you clean up all the evidence that were there, which includes the following: two phones, magnifying glass, whiskey bottle, shot glasses, bathroom door (if you use), window in the office, front door, the ballerina, and the glass case Lauren leans against. 4) On the Loose - Make out with your friend, forgive them afterwards and then escape. 5) Trapped - Get out the car yourself. 6) Face to Face - Don't get the medicine for the man. 7) Killer's Place - Stay where you are and wait until the scene ends. 8) Old Warehouse - Fail the sequence on the conveyer belt and rescue Shaun with Ethan.
