Why Alphinaud and Alisaie are so well treated despite being just kids

[EagleDynamics]

Not exactly. The WoL and Scions become persona non grata. No blame was attached to Alphinaud by those in power. How Alphinaud himself felt may have been established in the cut scene. But the real perpetrator died at the banquet, and the main corrupter of the Crystal Braves warmly embraced death while performing a summoning ritual two expansions later.

its not that alphi is being blamed for the assassination attempt itself but he was still very foolish for creating a company which had people working for teledji and lolorito. obviously the traitors themselves are the real perpetrators but alphi couldve at least done something to make sure he wasnt hiring spies. being negligent has its consequences.

Literally half the party in XII are teenagers lol. Ashe is 17 in the prologue, 19 in the main game.

The claim being contested was that FF hasn't had a single main party character over 19 since FFVII. Half the cast would be greater than 0, no? If so, both XII and XIII stand as counterexamples.
