well it might end up as following:
1-BB is back with his new nakama and they will thank luffy by taking down magellen
2-or jimbei coming back with ship then tell luffy to hurry which could be :
2-1 someone will stay behined either mr.2 or (mr.3 << most likely)
2-2 Mr.3 will make a cell of wax which will be really funny to have magellen in jail xD
2-3 luffy defeat magellen <<< really hope not since magellen is just too awesome to loss to a rookie :)
3- magellen need to go to the bathroom XD
i know most of them are weird but i just wanna say them anyway
