Stranger Things 3: The Game

Starting in Chapter 2, walking near the flower shop in Hawkins Square will spawn this quest. Don't bother with the back-and-forth the game wants you to do here – just find the three notes in the other rooms, then approach the woman in the bathroom and talk to her several times to get the key required to access the last part of the quest. You will unlock this trophy when you free the woman from the bathroom and talk to her outside.
