Yeah, but how did they get away from the people they were fighting in order to get in his way a second time?
It's literally,
1. Moria stops Luffy
2. Jinbei jumps in to fight Moria
3. Luffy continues on
Then this week
1. Moria stops Luffy again(which no explanation of how he got away from Jinbei in the first place)
2. Jinbei jumps in again to fight Moria again
3. Luffy continues on
And it's pretty much the same thing between Kuma and Ivan two weeks in a row also.
