In chapter ‘Stormy Night’, follow these steps:
– Serve dinner for Todd and Alice.
– After an altercation that has Alice run upstairs, Todd will tell you to stand still. Instead, move and run upstairs to Alice’s room.
– Pick the option to RUN with Alice.
– Hide in the room on the right side of the hallway by the stairs by holding down circle.
– After a while, Kara will automatically leave and run downstairs with Alice. Press circle to open the door and complete the button sequence.
– Once outside, get on the bus – this ends the chapter and unlocks the trophy.
Note: You can also choose to lock yourself in Alice’s room and escape via the window if you found this clue in ‘A New Home’.
