You were a Crewmate, and you were on The Skeld. There was a Impostor among everyone, including you. The Impostor was trying to kill you all, and you knew who it was. It was Pink, the one no one else suspected. Pink knew you knew, too, and had been trying to convince you not to tell anyone.

You were in the halls of The Skeld, when you passed Pink, and she stopped and started walking back to you.
