There is a distant part of Ignis brain that's registering everything Gladio's saying despite how the Shield is rambling. The rest of his brain is still taking in what's happening and trying to make him believe it's not some kind of dream. Perhaps he shouldn't be so surprised. After all, he'd gotten that scarf for Ardyn that allowed him to regain his sense of taste, but that seems to small compared to this.

Eventually, he takes a deep breath and just forces his mind to go still for a minute. It's then he really focuses on the fact Gladio is still rambling and he should do something about that. With a smirk stretching across his face, he throws his arms around the Shield and presses his lips passionately to Gladio's.

There. That aught to do it.
