His immortality back home is a problem. [The thoughts and questions that flood Ignis right now- he feels both somewhat excited and a bit on edge.

If he kills Ardyn here, would that mean the end of Prophecy back home?

Of course, he doesn't voice this because he doesn't want to sound like some cold-blooded murderer. Well- not right now. Later, if he has to be, he will be.]

I will gladly join my dagger to yours if he ever shows up.

[And he won't even stab him in the back. He'll look him straight in the face.]

Yes, actually. Apologies if we were loud at times.
