More trivia for The Expendables 2
Question: When Maggie asks Barney if he still thinks about Billy after his death, he says "We keep it light until we have to get dark. Then we go pitch black." What exactly does Barney mean by this?
Answer: "We keep it light" refers to their mood. They joke around and tease each other and have fun. "Till we go dark" is when they get serious for killing. "We go pitch black." Meaning as dark and brutal killing machines as possible.
