You and Vincent both worked the night-shift together at Freddy's, Vincent was rather obsessive and borderline psycho for you. One night while you were working the night-shift with him, you were busy beating the life out of someone because they said something about him, and let's just say he walked in at the wrong/right time. He seemed rather impressed more than he did concerned, because his only love was just as over protective as he was. He would go to such measures for you as well.
