"If I walked all the way here to say no, I would've brought officers with me to arrest you. They don't care too kindly about those who sail the seas freely." David mentally smiled at Raine's (He had overheard the girl introduce herself as he arrived.) statement, knowing fully well that his family tended to have a stick up their ass 24/7. Why else would they all act so rudely? "I'm here to accept your offer, only on one certain condition." 
David briefly thought of how to make this trip more worthwhile. Would he demand a payment at each stop they made? No, he would be quickly sent away with that one. What about asking to be second in command of the ship? With only three people so far, that wasn't going to work out so well. Then, finally, an idea struck him.
David looked straight at the girl captain, and spoke clear enough for her to hear. "If this ship gets into any engagements with other pirates or ships, I wish to have a portion of the spoils set aside for my use alone. When I leave the crew, or if we find this treasure you speak of, I will take the spoils set aside for me. Is this condition acceptable?" David stood still, waiting for the girls reply.
