On this page of the Disco Elysium guide, you will find a walkthrough for the Prove your authority to Titus Hardie quest.
The goal in Prove your authority to Titus Hardie is to prove that you have authority - Titus is the leader of the Hardie Boys group.
The task can only be performed on the 2nd day of the investigation, after completing the Interrogate the vigilantes quest. During it, you will have to pass a difficult Authority skill check. You can make it easier by:
- Doing the autopsy and finding the bullet (Find the bullet before you get fooled);
- Doing a side quest for Joyce - The Jam Mystery and linking Hardie Boys with drug smuggling;
- Completing Open apartment door for Evrart side quest;
- Mentioning that Evrart told them to cooperate;
- Discovering that 8 people participated in lynching (there are only 7 people sitting in the cafeteria);
- Warning Hardie Boys of tribunal carried out by mercenaries (Joyce's info on the lynching quest);
- Finding a witness (The smoker on the balcony and Interview the Sunday friend quests).
Passing the Authority skill check will make Titus reveal information about the woman who was allegedly sexually assaulted by a mercenary – this triggers the Speak to the assault victim quest.
