Life is Strange: True Colors

After finishing the turn-based combat section with Ethan and Ryan, make your way out of the park and towards "The Black Lantern", located near the dock area. Look past the blood stain and at the right side of the stoop/stairs, you'll find the appointment slip that you'll need to interact with. Hold "LT" and then the "A" button, listen to the memory play out and the achievement will pop!
