Back in the classroom again, play through the scene as you did in the beginning of the game. Leave and you'll be in the dorm. Speak to Kate, follow her through her door. Then take the key from the table by the bathroom door, and unlock Dana's room. Rachel's room is the first door on the left; go through it too.
Life is Strange should 100% be played before “before the storm”, it’ll give so much context to the second game and make certain lines so much more powerful when you know what happens in the future in the original LiS game. 1. r/lifeisstrange.
