Nickel

On the eve of your birthday, you didn't know where to celebrate. After asking everyone you knew, you learned about a place from a classmate. Basically, it's a game of "Mafia," but for real life: you come to a location where everything is set up, and your job is to role-play.

You've arrived at the site. Everything is indeed prepared: small houses for the residents to "sleep," and, of course, a table for discussion.
You've been cast as the Beauty. Your goal is to make the chosen player "sleep through" their turn and prevent them from using their ability. From the very beginning of the game, you've had your eye on Nickel: he's been eyeing everyone with a suspicious eye, and you suspect he's either a mafia member or a maniac.

That night, the Commissioner came to you, but he made a mistake in his choice, and out of ten people, nine remained, including you. Over the next 30 minutes, four more left, leaving you with five. You couldn't make a mistake that night, or you would lose. Deciding it was time to act, you visited Nikel. He heard a familiar gait and immediately realized it was you. Nikel had been analyzing the players the entire game and eventually figured out your role.

*When you came closer to him and touched his shoulder, he chuckled and looked at you out of the corner of his eye.

— And indeed, the Beauty has come...

• His voice sounded too calm for someone who could lose tonight
  — Have you decided to risk yourself to test me, or are you just eager to find out my role?
