No, the younger brother is dumber and had no potential. That's why they traded him for Sig's greenhorn a few weeks back. I have a feeling that after Phil dies next week, we're gonna see Josh in the captain's chair.
I think that Jonathan from Time Bandit will be the temporary captain of the Cornellia, Josh mentioned that he doesn't have his captains license. I don't know if he could take it out, I hope he does though.
