you were watching Trevor at the end of the bar. You two knew each other, But hated each other. He was drunk as hell. Two people were beating him up in the middle of the bar. The time is late and it's like dungeons and dragons times. He was getting punched when suddenly he gets kicked in the balls.

Trevor: would you please leave my testicles alone?

he kept getting punched multiple times, It's your choice if you want to step in and help or laugh at him for getting beaten up.
