The chapter contains a detailed walkthrough for the second portion of the bonus episode of Life is Strange: Before the Storm. This part focuses on the events taking place in the attic, as well as getting there in the first place.
Entrance to the attic.
Having talked to Chloe, Max needs to get to the attic. The entrance to the attic can be found behind the door shown in the screenshot.
As Max is not the tallest one in the bunch, she needs to prepare herself some assistance in reaching the entrance to the attic. Your first platform will be the CRATE located on the left. You'll have to MOVE it.
The crate alone isn't enough. You'll also have to get the stool from the bedroom of Chloe's parents. The stool is by the closet.
The last thing you need to stack, are books. You'll find a bunch of them on the bookshelf by the stairs. Pick them up and place them under the entrance to the attic. This will enable Max to reach the hatch.
Once Max gets to the attic, she'll make a photo of the decoration. To get further, you'll need to PUSH the old chair.
Max will enter a new section of the attic. To proceed, you'll have to look at the old desk first. This will unlock the option to PULL it.
Once you've moved the desk, you'll be able to PULL the closet.
Then, you'll have to move the desk again. This will open to way to the old refrigerator, which will also have to be moved.
Having moved all the furniture Max will be able to reach the amulet. TAKE it.
Max will look through the window. Chloe, who's playing outside, will notice her.
