^Bassoonist hates Perona.

I do not. I like her new design, I just think the reasoning as to why she had to accompany Zoro is faulty.
Zoro needs some one to navigate for him. I think in Skypeia he took a wrong turn 20 feet away from where he started (or maybe it was Enies Lobby). That's part of his character; he is the absolute worst at directions. Having some one go with him only makes sense, especially if we assume Mihawk's Castle is far away from the Archipelago. Even Sanji, Ussopp, Chopper had help getting there; why wouldn't Zoro?
It's a VIVRE CARD. I don't see how Zoro could get lost with that, unless he lost it, of which Perona wouldn't have been any help for him anyway. Sanji, Usopp, and Chopper all probably needed the help of their islandmates. Chopper did for sure, it can be assumed with Usopp, and Sanji, well, I don't know. It probably just wasn't an offer he could refuse. lol. (they probably wouldn't let him take one of their boats away for good, I don't know.)
Zoro on the other hand didn't need Perona. Mihawk gave him a boat, and he had the vivre card. Add that onto the fact that Zoro is a very independent person and would not even begin to think of asking Perona to join him. Nor would he even know that he needed her help (if he did, which he shouldn't have.)
But whatever it can be ignored, as I said. Perona isn't joining the Straw Hats. She was just there to fend off the marines, like everybody else's islandmates were. I guess a character in such a small role doesn't need a good reasoning? =P
