Dumbass, indeed. An amused sound comes out of him, more a huff than a proper chuckle, while imagining the scene in his head. Even Guts can have a little mirthy laugh from time to time! There were a lot of loudmouthed idiots he's met on the battlefield, so he knows exactly the type she's talking about. They never really lasted long, did they?

"You look pretty different from the elves I know. Should've guessed from the ears."

Honestly, he far prefers this scrappy fighter type of elf to the bugs.
