Turn 12 clear cutscene question...

I think he was talking about Summoner?

I took it the same way. Sometimes I'll do consolidated translations of important lines - for that one, I have:

It is said that there was once an art that allowed someone bathed in the scattering essence of a fallen primal to recreate its power.
I am not [completely/wholly/perfectly] a primal, but what strength remains me I give unto you ... that you, too, might protect that which you hold dear.

Likewise, I, too, thought it could imply that we might see them harness the Phoenix-egi one day as a last-resort.

One one hand, they plainly said that no one can know about Phoenix, lest inevitably somewhere the misguided will summon it in hopes of seeing its restoration of the realm completed (with disastrous and antithetical results). On the other hand... in an all-or-nothing scenario with no (or trustworthy) witnesses, it could come in handy. It would also create a kind of "full circle" moment for one (or, hey, both, why not) of the twins to finish off a nemesis with a Phoenix-egi dash through the chest a la Louisoix to Bahamut..

Not going to lie, it was one of the first things I imagined happening to Elidibus when I saw Alisaie creepin' on him and Urianger in Gubal.
