For this achievement all of the fables are story related except one as long as you follow the right path!
When you go visit Beauty and beast at their apartment as your leaving you will be set with two choices you can either visit the butchers or the pawn shop first, you need to choose the pawn shop or else you will miss two fables and have to restart.
When you get to the pawn shop the first fable is story related and will unlock as you are talking to Jack, but the second fable you need to tell jack that you want to look around for a little bit. Now when you’re walking around the shop investigate the pin cushion which will give you the last miss-able fable.
All of the rest of the fables you will pick up naturally playing through the episode and your achievement will unlock in chapter 5.
If you get stuck on anything or want to see where all of the fables are I have included a video below with all of the locations in this episode.
