After Sango re surfaced he looked at her and asked him if he wanted to know how she stood under for so long, he nodded as he was honestly curious, yet was shocked to find out how she was able to.... this girl had fucking gills. Well he was technically right, at her cheating. As he can't really grow gills. He was more curious as to how she could breath on land, maybe she had lungs and gills, so she could do both. he saw her look down rather sad which made him look around not quite sure what to do. He would hug her but considering that neither of them had clothes on, he pat her head. "Don't be sad? They are very pretty gills."
