Wrong-o, after the Lete River, the characters that join your party will all be level 99 if you leveled up to 99. Locke being an exception since he left the party and came back. Everyone else is new. (Locke will catch up when you get him back in the WoR if you choose to do so).

The reason I put four characters (by the way) was because I insisted on getting Mog/Moogle Charm because I'm that damn lazy.
