Why are alisaie and alphinaud in Dawntrail?

[KazukoHimura]

I mean they should be. But the twins in Dawntrail are just souless husk with their names

What happened to Alisaie's sass and brashfulness? And Alphinaud with his political knowledge and experience on nation states had literally nothing to say about Tural

What happened to their friendship with the WoL? They didn't even bother checking on us, or even each other, Krile, Erenville, etc. after the first dungeon. As someone who has had both RP and RL friends do shit like that, it honestly freaking hurt. For a game about the power of friendship, they seem to have dropped the ball on showing one maintained.
