Episode one: Awake
As soon as you trespass the old mill, there'll be an RV(That's right, it's Frank's RV) in the premises. You can spot that RV pretty easily. Go to the other side of that RV and you'll see the option of writing the graffiti.
The second one is done near the entrance of the Firewalk concert that's going on. Near that entrance, you'll see a saw to the right (a bit) of the entrance.
The third graffiti is located in Chloe's room near the door. You'll see a unicorn poster near the door which can be ripped off. After you rip that off the wall, you'll get the option to draw the third graffiti.
The fourth one will be done in the garage, inside David's toolbox. After you take the socket wrench form the toolbox, you'll be given an option to draw the grafitti in the toolbox.
The fifth one can be done on the building near the parking lot. Go to the right side of the entrance of that particular building and you'll get the option to do the graffiti.
The sixth one will be done on a poster in the dressing room where Rachael will ask you to get the belt from her bag. As soon as you enter the dressing room, you'll see the poster of the play on a door. Go near it and you'll get the option of doing graffit on either Nathan or Rachael.
The seventh graffiti can be done in the train you'll accompanying Rachael with. As soon as you move the small crate to sit down with Rachael in the train, go behind the place where you moved the crate from, and you'll see the graffiti place where there'll be a writing to your left.
The eighth graffiti can be done on the statue on the park. Just go near the statue and look at it, and you'll be prompted to do so. This one is pretty easy to spot too.
The ninth graffiti can be done in the junkyard after Rachael leaves and gets angry. You'll be prompted to smash everything you see. But, to get this graffiti, you fist have to smash the sign board that's present and then smash the paint box near the sign board. The paint will spill on the sign board and you'll get the option of graffit on the sign board.
The last graffit of episode one is done in her dreams after she finishes smashing the junkyard. In that dream, you'll see the poster of the Blackwell's play. You'll have to look at the poster first and then move the poster. After that, look at the bottle below so that you'll get your marker to do the graffiti. Once you get the marker, look at the spot where you moved the poster and you'll get the option to do the graffiti.
