Keeping secrets from friends seems to be a theme of RPGs, but man as I run through FFX for the umpteenth time it really struck me how awkward it must be by the end of the game for everyone.
Lulu was keeping it secret from Wakka that Luzzu convinced Chappu to get into the Crusaders (where he then was killed). She along with the rest of the group kept Tidus in the dark about what was to happen at the end of the journey.
Auron was keeping it secret from Tidus and others that he is really dead (unsent). He also kept it secret from everyone that the whole journey was one big fucking sham and that one of them would need to become the Final Aeon if they were to defeat sin (and thereby become Sin, whilst Yuna dies), which seems to me pretty fucking mean spirited. I still can't see an advantage to him doing that, his nonsense about them needing to see this for themselves just rung hollow.
Tidus is keeping it secret from everyone but especially Yuna that he is actually a dream of the Fayth who will disappear if they kill Yu Yevon.
Yuna was keeping it secret from Tidus that she would die at the end after summoning the Final Aeon. She also kept it secret from Wakka that she was Cid's niece. Although that makes sense, Wakka was an asshole. And she was keeping it secret from everyone for the longest time that Seymour was a total asshole who killed his father.
Rikku was keeping it secret from Wakka that she was an Al Bhed. Also understandable with Wakka being asshole-tier.
Kimahri kept Auron's secret from everyone about being an unsent.
And gamers everywhere are left in the dark as to why Lulu would ever marry and have a kid with asshole dumbass Wakka. Maybe they both had the whole blindly following the teachings of Yevon thing for the longest time going for them?

So like if after the game ended they all sat down to dinner and talked, I think it'd probably be a pretty silent dinner. I mean it just seems like it'd take a little while to get past that shit, but maybe defeating Yu Yevon allows you to see what's important or some shit.
I'm thinking of other Final Fantasy games, but I don't know if the secrets-from-friends thing is as ever-present as it becomes in FFX. Most FF characters have secrets about their upbringing and past, and of course sometimes those secrets effect the others... but it seems like in FFX they all just happily keep shit that would like obviously negatively effect the others if revealed. Seems like a poor foundation for friendship.
