Snatch and Grab
B went searching for women he felt would be worthy of being married to his brother. His first stop was a gathering of the royal families at the city center. He drove around and noticed three beautiful princesses that were talking to each other. B immediately stopped his van, shot the nearby bodyguards, and instructed the princesses to get in his van. He escaped during the chaos and confusion. He then arrived at his brother's house and let him have his pick.
Opportunity
B saw the princesses. B took the princesses.
Author's Note
My stories are based on the Mahabharata PDE. At one point in the story, Bhisma kidnapped three princesses for his half brother Vichitravirya so that he could continue the blood line. They eventually let one of the princesses go because she was already in love with another king. I tried to take a modern approach, hence the van and shooting.
