So, I'd been seeing the Ifrit was right all along! bit posted around, and I knew in ARR, at least, he specifically says he can't "smell the taint of another" upon us. I remembered ARR Ifrit dialogue being remarkably similar to 1.0 Ifrit dialogue, but it seems in some regards the passage of time has addled my mind, so here's a quick transcription of 1.0 Ifrit (with generic Companion text in brackets):
You avow yourselves blessed by gods, yet lack the capacity to summon them to your aid. (Rocl's note: He's likely talking about us introducing ourselves as being members of The Path of the Twelve)
To which do you kneel, mortals?
[I kneel to no primal]
Fools. Blind to the grace of those who would grant you protection and bless you with their fortune.
[Protection? Who protects me now then, eh?]
Your blindness is born of ignorance. I smell the taint upon your soul. Is it Garuda...or Titan? Perchance...Leviathan?
[Who the hell are those guys?]
Vex me not, mortals. The Paragon warned of the godless blessed.
There can only be one true god in this world, and those without cannot be allowed to roam unchecked.
Yet the Paragon has entrated that I spare you, and so I shall—on one condition.
Vow that you shall forsake the summoning of Another. Do so, and your sins will be absolved. Refuse me, and your soul will burn for eternity.
[What? You mean I can summon a primal!? But how?]


and 2.0:
Forsooth, thy frail mortal frame can serve as vessel to the blessing of but One.
Yet I smell not the taint of another upon thee...
The truth of thine allegiance waxeth clear─thou art of the godless blessed's number.
The Paragons warned of thine abhorrent kind. Thine existence is not to be suffered.


It's weird he can't figure it out 2.0 before the fight, but during the fight, specifically the end he references the blessing of Light. Garuda tries to temper us too, fails, is confused for a minute and then after we rip a Crystal of Light out of her and complete our six set smells Hydaelyn. It's weird to me it takes both of these Primals a minute to figure it out....

Also fun to note Paragon becomes plural after the Calamity :P
