Kilika : After the scene in the temple, and with the summon Ifrit learned, backtrack to the main village of Kilika: the woods should be simple to navigate with the Ochu out of the way. Simply head along to the dock at the southern part of the village and you can leave the island.
S.S. Winno : After you regain control, be sure to examine the chest for a Hi-Potion , then go east and out of the room to find O’aka again. As before, he’s requesting you donate him some money to give you a discount on goods in the future. They’re cumulative across the game as you give them out so give him what you can.
Head up to the main deck after kicking O’aka in the gil-sack and speak with Yuna, found near the bow. Also be sure to loot the bridge on the way for the Al Bhed Primer Vol. V . Go find Wakka and Lulu next: they’re found towards the starboard side of the ship, up the stairs, and go up there several more times - these latter times are optional, but elaborative.
Anyhow, also head to the deck of the ship. (Note: You may want to save before this! It’s a one-time (for now) chance to learn the Jecht Shot , invaluable for the upcoming Blitzball tourney!) Examine the bumpy-looking blitzball and there will be a brief scene. When directed to, press X and a direction on the D-Pad depending where the message on-screen appears. So if it appears at the top, press up and so on. Doing it correctly earns you the Jecht Shot, a great Blitzball skill, and a great aid for obtaining some stuff for Wakka in the late-game.
Anyhow, there will be some more scenery before reaching Luca. (God, I love Luca.)
