I'm using a few of the FFX-2 guides that I think were written for the Japanese version, so I don't know if they are correct or not.
They tell me, after I'm done with the chocobo mission that I should head back to Mi'hen road, and I'll see Clasko and Hikaru standing next to each other, and if I 'choose the first option, I can get them on board Celcius.' ?Well, I believe Hikaru=Calli, because it doesn't make sense any other way (they say Hikaru where it makes sense that it should be Calli all throughout the strategy guides... soo...).
So after I completed the chocobo chase mission, I return to where I met Calli like it says, and... Clasko isn't there! ?I can talk to Calli, and she boards the ship, but no Clasko!
I don't think I talked to Clasko at all before the mission, so maybe that's my problem? ?Where would I have talked to him?
Also, it says to go to the Nagi Plains as the next step. ?It seems like Nagi Plains=Calm Lands? ?Cause they say the Monster Arena is there so... ?Maybe it's a specific place in the Calm Lands though?
Okay, I found him in Mushroom Rock Road, he runs off saying he's gotta find his place in the world. ?Too bad I did this after I did the chocobo quest and got Calli on board Celcius... now to do it before.
Sweet! It worked. Sorry for not looking harder before I posted this up, thought I'd never find him though.
