This page of our guide to Life is Strange True Colors contains a description of Part 3 of Episode 5. It covers the visit to the family home and a meeting with Alex's dad.
You will spend this part of the chapter in your family home. You'll wake up moments before your father and brother fight.
Gabe will show up again. It will remind you of another traumatic day that changed your life.
Alex isn't feeling well. She'll hold on to her plushie, just like she did years ago.
You need to turn the music on. At this point, you have no other task. Simply let Alex get into the song and pretend that nothing's happening.
Alex will wear headphones so she can't hear the argument. This won't be enough, unfortunately - you'll have to repeat this sequence to make the same events happen that did years before.
Visiting the apartment
This time, you can move and control Alex's actions. There are many objects in the apartment that you can examine. Look closely if you want to delve into the history and learn everything about those times.
When you're sure you're ready to proceed, approach the door and touch the handle. This will trigger another cutscene.
It's going to be a lot worse this time. One of the biggest traumas of her life will replay before Alex's eyes. Upset, she will throw the necklace she got from her mom at her father. He'll take it, close the door, and Alex will be left alone with her older brother.
Another burst of emotion will end this part of the episode.
