Ignis grips Prompto's shoulder tightly when he hears his words. Deamons? Danger? What is Cor talking about?! Requests like these at this time?

"We cannot go with you, Marshal," Ignis repeats what Prompto said, loud for Cor to hear. "The darkness... has been purged. There will be no more daemons. You don't have to worry about that." He steps closer to the Citadel stairs, head tilted a bit.

"Our duty is still not over. And it won't be until we see our King to his resting place. I apologize," Ignis bows briefly to him, "but we cannot follow you to Hammerhead."

He wishes he could seek Gladio's gaze for approval of this decision. Right now, he's doubting every thought that goes through his head.
