Yeah I think they're awesome. I was a bit out of place for Perona to fill in the role of Zoro's mentor helping him, but I guess it would sorta ruin the whole dynamic fof the scene for Mihawk to come barging in and he probably sent Perona in his place.
I think Zoro and Mihawk's dynamic is quite awesome, in that he's been trained by the man he's actually going to have to beat to claim his title. And I just wonder if Zoro will actually kill Mihawk in the end? … Also Sanji with the Transvestites. Very funny stuff, but he also has come to respect them deep down I think. I wonder if they've taught him to overcome his chivalry and treat female enemies as any old enemy?
