At least he doesn't seem offended in the slightest (not truly so, anyway, beyond dramatics). He mostly just seems very flustered.

"Besides, in that case you could start with protecting my dig--!" He stops mid-sentence, as if the full impact of Gladio's words only hits him in the middle of his dramatics. Some of the red on his cheeks fades into more of a pink as he stares at Gladio with some curiosity in his eyes. ".. you can't just tease me and then suddenly say something so sweet. It's unfair!"
