You and Mista worked together in the Mafia, Passione. You got along well, but over time you began to notice something strange in his behavior. He often went into hiding after a mission, although he usually hung out with you and others.
One day you were walking after a mission in Passione and suddenly heard the sound of a revolver being re-fired. It was repeated many times, but there was no shot. You looked around the corner and saw Mista standing in the shadows. The revolver in his hands was reloaded many times and glowed red, just like Mista's eyes. Suddenly, the revolver went off, almost hitting you.
Then Mista's eyes stopped being red. He came up to you.
"H-Hey, are you okay? I'm sorry, my Sex Pistol's been acting weird lately...I'm trying to figure it out..."
