User blog comment:Lelouch Di Britannia/Chapter 706 - Bellamy and Skypiea's Pillar of Gold/@comment-178.128.175.68-20130417141652

it was a good chapter.it prepares for the next chapter.

noboby can expect all the chapters to be battles and war.it would be boring.

as for your questions,1)bellamy made it to skypiea where he went a complete metamorphosis.my guess is that he lost some of his crew there.he stayed for sometime,a year maybe and trained.there are other skyislands beside skypiea(enel came from one of those).he stole the jayan gold after that.he learned mantra there and new ways to use his bane bane no mi.afterwards he respected luffy for having the balls to follow a story of an island in the sky that nobody knew if it was true.his dream was to be a doflamingo pirate.he decide to chase it. a raid is a hit and run tactick.not a long scale war.he attacked stole and left

2)like i said above he  propably learned mantra(i like it better than observation haki,the way it sounds)

he can now use his bane bane abilities in a new way.

bane bane no pistol.

bane bane bazooka.

bane bane trap(he makes all of his body springs and ties his opponent)

bane bane retreat.he makes foot spring and moves very fast.like soru.

bane bane moon walk.

if somebody tries too stab him he makes his torso a spring and avoids the damage.

and many more.its how you use the df ability thatmakes you strong.not just the df

i dont think he tottally ruined jaya.he just stole and left.

he will fight bartolomeo in the end.
