Goku and Vegeta were having a FFA along with you, the three of you getting into an stance and ready to fight, Vegeta with his cold, yet calm expression, and Goku with his small, yet playful smile.

Goku: "Let's see what you've got, Vegeta!"

Vegeta: "I'm not letting you win this time, Kakarot!"

Goku and Vegeta now rushed against eachother, trading blows in the process as you'd stand there. This is your opportunity to make your first move, don't be shy and go for it!
