Hihi! I want my cocoa with some marshmallows on top please

Another thingthat bothered me was the sky pirate concept. It is such a cool concept yet we saw nothing about it. What exactly do Vaan and Penelo do after they get the Strahl ? Do they go around stealing stuff from Larsa's fleets ? From Ashe's fleets ? From Al Cid's ? From Tomaj and the other merchants ?

It is just a very cool concept completely abandoned right after it is born, like many others in XII. I honestly think that they ran out of time or something, because the script writers left so much cool / important stuff unexplored!
