It's charming, really, to see Ignis blushing over something that was the most well-known secret in the Citadel for a time. The sort of thing that only drives home just how young he is here. Cor has seen and heard far more damning evidence than a blush. It's inevitable when the safe spaces were so few and so densely populated and adrenaline is the only thing keeping people alive day in and day out.

He has suspicions of where Ignis is going, there are few enough people whose relationships with him would warrant telling Cor about. So when he says Noctis' name he's not surprised but there is a flash of something pained in his eyes, there and gone in the span of heartbeats. Good for them. That they have found this place that, whatever else it may be, has given them the space and peace enough to let them care for one another is a comfort.

"Then I suppose Noctis and Gladiolus as well." He nods slightly, following the train of thought to its inevitable conclusion. "Prompto.... he and Noctis as well?" He's less sure if those two had something going on before the Crown City fell but it's more an uncertainty of if either of them ever said anything honestly about it rather than whether or not they acted on it. He'd been the one to put Prompto through an ever more intensive speed run of Crownsguard etiquette than Cor himself had gotten. Some marks are unmistakable, especially on such fair skin.
