Reynir can tell that Ami is happy, and relieved. She must have really been dreading this. And he knows his own reactions earlier had doubtless contributed to that dread. He wants to undo that, now.

And - oh, gods, Ami is... flying now, okay! Reynir's eyes go wide, but, honestly, she's got wings, of course, she can hover up off the ground! He just smiles at her, a little closer to his eye-level, now. When she calls him a flatterer he shakes his head, denies it categorically:

"No way! Flattering means it's not totally true, or I've got some ulterior motive, and c'mon. I'm not an ulterior kind of a guy."

More seriously, he adds:

"You're still you. I can tell."
