The Mugiwara tend to grow/power up after every major fight. Some simply add a bit of smarts/versatility to their method of fighting while others add whole new moves. And i think after the fight against Moria, all of them will be itching with the desire to improve in order to prevent a repeat of events.
However, i have to ask whether Luffy's desire will be hindered. i.e. will he not think as hard about powering up based on that fight as he would've done based on the fight against Aokiji. Especially considering that he not only had a victory but he also (as far as he knows) escaped the fight unscathed.
In contrast you look at Zoro and Sanji. The last two concious and you have to think that right now. They're beating themselves up over their inability to protect the crew. I think less-so for Zoro as he took the damage but in a way, i think he'll want to get to a level where by he'll want to be able to take that damage any time and even prevent Luffy from ever getting that damaged.
Would it be wrong to speculate that the growth coming out of this arc would be;
- the rest of the crew
Or am i simply considering this too heavily?
