Shirahoshi looked quite distressed when she left with Jimbei. I think that Luffy was beaten by Jimbei, seeing as a jet kick was blocked with minimal effort by Jimbei, though if Jimbei were better than Luffy, the punch to each other shouldn't have had the same effect.
I think that in the climax, when you don't know who's going to win, (jimbei v.s. Hody/Hodie/Hordy) Luffy will go like 'jet... pistol!' and blast hody away like it's no one's business, but one thing I don't like is that he always uses his adapted jet/balloon attacks... I always liked it before 3D2Y when luffy aways used it as a finisher... and no/minimal strain on luffy's body when he uses such a technique really is unrealistic.
Even though Oda and Mitsutoshi are friends, the manga toriko has more technical terms and one piece just brushes by them... I bet there will be no explanation for the pill, either. He just thought, 'a good way to make a battle is a weak guy takes some pills,' but he couldn't figure out how the pills would help exactly...
I was about to use the world medicine instead of pills but pills sounds more blunt and sinister.:flaw: to Oda for mistakes in this arc, like the 150 km one!
