"Just a hint as to what step you need to take. You're going to have to take the square root of a number." Don continues to smile, having fun with this game. He's wondering if he should add on that if they get it wrong even with a hint of they have to give up two things instead of one. He'll bring it up after Vincent answers the question though. After all he doesn't want Vincent to quit playing, not in the least.
