Square let us redo quests on different classes.

Shhhhhhhh.

We don't talk about timelines and quests. You can cook something for X, but X is now the ex X. But ex X is still the X because X was the X in the time period which you completed the quest even though that time period is long gone, despite you completing it now.

While you can do content X many times (Titan), the story for content X (gather stuff for dinner before fighting against Titan) you do only once.

Also ex X always happen after X in the story (You have to defeat the first summon, so the beastmen have a reason to summon a stronger version)
