This page of our guide to Life is Strange True Colors contains a description of Part 6 of Episode 5. It covers the events at the bar and the ending of the game.
The meeting at the bar
Alex will enter the bar, all bruised and battered. Everyone will be shocked by your condition. You tell the truth right away, you have no control over it, it's a plot point you can't skip.
Steph will trust you and stand by your side as long as you have given her the rose before.
Duckie will be on your side if you came to him during the festival and made him feel better. This will improve your relationship, and you will have his support.
Eleanor will be on your side if you didn't tell Riley about her illness at any point in the game. If you did, Eleanor will think you're dishonest and untrustworthy.
Charlotte will be with you if in Episode 3 you didn't take away her rage and let her deal with her suffering on her own.
Pike will help you if in Episode 4 you took away his fear and didn't sign the affidavit.
Ryan won't believe you if you didn't build a relationship with him and didn't give him the rose. This will infuriate his friend.
Even if everyone turns their backs on you, you'll prove the truth. Alex will go inside Jed's head, she'll talk to him, and force him to confess his guilt.
After the bar scene, you go to the apartment. You need to go upstairs to trigger the final ending.
If you gave someone a rose before, that person will show up at your apartment. Steph will tell you that even though she wants to leave, she can stay for you. Ryan thinks he can leave, even though he wants to stay and he's counting on you to forgive him.
When you get to the roof, you'll meet your brother. You will talk to him and you will have to make the final choice. You can stay in town or leave. There are actually 6 endings to the game, we've described them on a separate page of the guide.
