Hilda spots the blush from a mile away. She's been trained in the art of teasing and learning when it's working is a necessary part of the art. It would be an absolute lie to say that a small part of her isn't a little bit pleased about being able to draw that kind of reaction from him.

Fortunately for him, there's more important matters at hand. "Would I be this upset if I was calling you a poorly sculpted statue?" There were better insults if she were trying to accomplish that.

"I saw you fight a wild boar. I didn't think you were out of shape, but I didn't think you were this fit." She hasn't forgotten his outrageous lie (?) about being an assassin. Even if Altair's physique added to his story, she still isn't fully convinced.
