Investigator

Ability

Each night, you must choose a player and an Agent role: you learn if they are this Agent role.

The Investigator wakes up and chooses John and the Analyst. John is the Analyst. The Investigator learns that this is correct, John is the Analyst.
The Investigator wakes up and chooses John and the Analyst. John is the Traitor. The Investigator learns that this is incorrect, John is not the Analyst.
The Investigator is malfunctioning. The Investigator wakes up and chooses John and the Bodyguard. John is the Analyst. The Investigator incorrectly learns that John is the Analyst.

As the Investigator your ability is very useful for testing the claims of other players. If a player tells you their role, you should check it that night to see if they’re telling the truth.
As your ability is very useful for destroying the bluffs of Subversive players, you will likely be a high priority target. You should keep your role a secret if possible, to increase the number of nights you have to learn information.

Each night, wake up the Investigator. Ask them to choose a player and an Agent role. Tell them if the player they chose is the role that they chose or not. Send them back to sleep.
