In which episode did Luffy say the following quote? I want to know in which episode Luffy said the following quote: 


  You came without fear. Don't have any regrets, no matter what happens.
  This is the duel you wanted.
It's from Episode 236: this is a clip from the episode at the scene you mentioned.

The context is the duel between Usopp and Luffy: after Luffy decided to buy a new ship and abandon the Going Merry, Usopp abandons the crew and challenged Luffy to a duel. The cross talk is between the two of them just before the duel began.
