Why are references to the sequel (FinalFantasyX-2) in this game's page? Move them (such as references to Paine, Shuyin, and other sequel-only characters) to that page. If you have to (such as for Belated Happy Ending), say that "it gets fixed in the sequel," but move the explanation there. Final Fantasy X and FinalFantasyX-2 may have the same continuity, but they have different trope pages for a reason. Fixing this alone would reduce the page size significantly (especially the character sheet, where links to character pictures are provided instead of displaying the pictures to avoid stretching the page).
