Not in the habit of gossip, no, or really going into any detail at all about what he does in his personal time. That Kate and himself are not terribly covert in their affection towards one another is a moot point, if it hasn't been observed by Glacius (which is fair enough, when he may have simply never come across them bidding each other goodbye before work).

"The blame can't fall entirely on you. I could have made my own introduction." It isn't how the individual looks that kept him from doing so, after all. Ignis observes the transformation to a far more familiar form with quiet, muted interest and none of his previous (however brief) wariness, and with no hesitation shown he takes the offered hand in a firm, polite grip.

"A pleasure, I'm sure," he says with a quick smile. "My apologies for any offence caused. I was entirely unaware of your particular talents."
