Also scions either go through a job change when new jobs are released (Thancred, Alisae), or a new NPC with that job joins the scions sometimes (Estinien, Yugiri) or we have an ally of that job (Gosetsu). If the next job released -IS- BLU (still big IF), it would be likely that Alphinaud would either demonstrate BLU-like abilities soon (like Alisae did with her Aether sword), or a new BLU NPC will join the Scions. This is because the Scions sort of represent the prototypical FF cast party made up of different classes.
